Hunting with my Ar15/MSR

7/23/2015

8 Comments

 
     I love hunting with my AR15/MSR with a 16.5” barrel chambered in 5.56 NATO loaded with either 65gr sierras or my personal favorite 70gr Speers. I have taken lots of deer with those combinations and had never had any trouble recovering a shot deer.   I have not taken a few shots on some nice bucks because I thought they were just a bit out of range for the cartridges capabilities, at least as far as the self-imposed limits I placed on it.  I had also carried and used an Armalite .308 win and Armalite 300 RSAUM both being capable of taking deer at longer ranges but both very heavy to carry. I wanted a lighter gun that would be that would be flat shooting and still give me more energy on target at longer ranges if needed.

The 7mm Valkyrie/7mm VAR is perfect for this role, it’s exactly what I wanted, it’s a cartridge that fits in the in the AR15 platform (so I could keep it light weight and use more available components) that could shoot a heavier bullet but still be flat shooting. Where I deer hunt most of our hunting is in thick woods or swamps, located near Holcombe, Wisconsin it’s in the northern corner of Chippewa County in Northwest Wisconsin. We hunt tamarack and tag alder 


swamps surrounded by raspberry bushes so thick cottontails could not make it through without losing some fur. When we are not doing drives (yes, it’s legal in Wisconsin and part of our hunting tradition) we may sit in stands overlooking swamps or on the many irregular shaped farm fields and logging roads.

Looking out of Hoyts stand thick cover means you need to take precise shots through openings in the brush.

Looking down the side of my 40, that’s 440 yards of possible shooting, the 7VAR can drop a deer anywhere along that tree line.
  Most of the time I  can’t even see a deer past 20- 50 yards but we do have some stands on swamps about 200 – 500 yards across and on some  long straight logging roads. I prefer short light semiauto rifles/carbines for our type of hunting, it’s not uncommon to see several deer at a time and being able to have quick follow up shots on target are a real asset. Having a flat shooting semi auto allows us to make precision shots through the brush with fast follow up. Despite popular myths even a small twig will throw of the trajectory of any bullets.   Slow moving round bullets will actually deflect more than a fast moving long bullet.

  The 7mm VAR fit my requirements perfectly, with my 16.5’’ barrel and a 2x7x33 or an Eotech my gun weighs 7 pounds. It is  capable of pushing 120gr Nosler ballistic tips 2800 fps, 130gr Speer 2700 fps, 139gr Hornady SST at 2560 fps, 160 federal fusion at 2466 fps, 168 Nosler custom competition at 2425fps.   This is more than adequate for deer and Black Bear out to 400 yards or more with most loads.  This Carbine was built for my son Hoyt to shoot out of a stand.

  The 7mm VAR is for reloaders only and does not require anything too special to load if you buy brass converted already. Hodgdons Leverevolution has been giving the best velocities, CFE223 being second, with the 130 and up class bullets, H335 and 8208BRX have been great with the 120s and up. I also have a 20’’ barrel and the velocities have been consistently about 28 fps per inch faster, longer barrels will get even more velocity. Many loads have already shown SUB MOA capability with a few less than .5 MOA.

  The brass I use is made from 6.5x47 Lapua. It has a small primer and will give the best case life. It can be made from surplus .308/7.62 NATO or other 308 or 6.5 Creedmoor brass but it is much more work with lots of cases needing to be scrapped due to malformation when sizing. It’s just not worth all the work compared to the lapua brass.  

  Load data is being worked up for many different bullet, primer and powder combinations. We will have a complete load book eventually with a load to cover just about any practical use with real world data. All of guns are shot off the bench, they are not a test barrel locked in a vice. The data is also being shot in barrels 16.5” to 24” in the Ar15 platform.   We have shot Speer 110gr TNT up to Nosler Custom Competition 168gr which are both  super accurate even out of the 16.5” they are near one hole capable at 100yds. This could easily be a do it all hunting rifle for many people, from taking predators and varmints up to bear and elk. It will defiantly be the coolest gun in Deer camp.

  Others using the cartridge with heavier bullets will  load them longer (2.345’’)so they may (window) or cut out the front of the magazine,  ( there is a good video that shows how to do this) I prefer to only shoot bullets up to 145gr for deer  and load all of mine to magazine length or slightly shorter. The PRI 6.8 magazines work best, they are waffled and are much stiffer, just holding one in your hand will let you know it’s built to be tough. Cheaper mags can be used but they will not have the capacity due to the thin weaker construction letting the sidewalls bulge out. So far my favorite bullet has been the Speer 130gr with CFE 223 it has been super accurate with several groups less than 0.5in. The recoil is not too bad either, the 16.5’’ was built for my son Hoyt who at 9 years and about 70# says it’s about like his .410 shotgun with 3” heavy loads.

One of the Swamps we hunt over. Deer can come out under your feet or 300 yards away. Either way it’s in danger when you’re holding a 7VAR, flat shooting makes it easy to shoot in between the branches
Picture
  The 7VAR has exceeded my expectations in every way. Having standard factory load 7mm-08 performance in a semi auto gun that’s easy to customize and easy to carry are a big plus for me. Who can deny the power and long range capabilities of the 7mm-08.

  The 16.5” upper receiver and carrier is standard stuff from BCM, the hand guard is a Midwest Industries 9” carbine lightweight free float handguard. It will wear an Eotech 552 for Hunting.  Loaded with 130gr Speer BTSP or Sierra 120gr SP either will be deadly on deer.

  The 20” upper is a billet from Midwest Industries with a BCM carrier. The hand guard is a Midwest Industries Gen2 SS free float. It is by far my favorite hand guard. It will wear a Leopold VX1 2-7x33 scope.

  The lower receiver pictured is a Midwest Industries billet with a Geissele SSA-E trigger, it’s nice and I have no complaints other than the cost.

  Ace skeleton stock is by far my favorite light weight fixed stock. The foam is nice on the face when it’s cold.

  I use Simmons 6-24x50 whitetail classic scopes for load development. The cross hairs are a little thick but  I use  the 1” orange target spots with the little black diamond and can line it up perfect every time and the glass is good enough even on foggy days. For $100 you can’t beat it. 

  The Nikon 223 mounts work well and were a deal, $59 at Cabela’s on sale, the 2 piece Nikon are also working out well with no issues.

   Both are Cerekoted Magpul OD green, and have the large BCM gunfighter charging handle, they are nice when you have optics or are trying to use it with thick gloves. Midwest Industries low pro gas blocks.

  We look forward to hunting this fall with the 7mm Valkyrie and I’m sure there will be many others using it in the near future also.

First range trip with my 7mm Valkyrie

So my first trip with the 7mm VAR was pretty productive. My main goal was to collect data for future loading and get a feel for the cartridge. I provided the targets for the hell of it, since some of the ladder tests shot better than my 5.56 AR. So I am really liking the X-Caliber barrel.

Initial impressions on the powders are as follows. LeveReloution : Still need to test more, but so far I like it. 8208 XBR : Its reputation for accuracy was seen pretty early on with the. Even with the ladder test 140 TTSX wasn't terrible. CFE223: This is a powder that should be avoided on barrels longer than 20", although if you have a mild charge on a 20" barrel you could still produce the double pressure spike. Please reference String 11 and notice shot 10 has a double pressure spike that almost mirror each other.

I have attached a chart of Optimal Barrel Times for different barrel lengths. (If you would like the Excel file, let me know.) It will provide reference for the exit time for images Pressure Spike 1 & 2. So in theory you should be ok with a shorter barrel, something I would want to confirm.

Rem 7 1/2(Lot#986) seems to be the goto primer, as CCI 450 & Wolf KVM-223M would produce double pressure spikes. Even though the Muzzle Velocity of CCI 450(Lot#K16U11) & Wolf KVB-223M (Lot#1-10) were slightly better than Rem 7 1/2. Reference String 1-3, these were my primer comparisons. String 4 A & B were actually shot first, to sight in the rifle & initial function check / troubleshooting.

With the rifle I did have some issues, FTE & FTF. The Failure to Extract was from the bolt cycling too fast. I was using a standard Carbine buffer. Forgot to bring my H3 buffer which I think would have solved the issue. Lost 3 brass to cycling issues, necks were too badly damaged for me to salvage. But in most cases the brass was turned around in side the ejection port area, and as my firing went on, the brass would just sit in the ejection port area. Glad I brought my Bob Led Sled, which allowed me to finish the day out at a slower pace. The Failure to Fire could have been 1 of 2 possiblities, the Voodoo Tactical lifeproof coated firing pin and/or the Wolf primers. I suspect its the firing pin since I was able to get the round to go off once I removed the BCG and cycled the bolt open to close and moved the firing pin. Re-inserted and would fire round. Had this happen with I think 1 CCI primer, but I'm not sure since I was in a rush to shoot off the ammo.

Overall, I am very impressed with the 7mm VAR. I knew that there would be a couple kinks to work out, especially the buffer/gas system relationship. But the round paired with the barrel proved to be a wonderful relationship. I have not had the best experience with Barnes bullets with my other rifle, but glad to see that this will not be the case in this rifle.

Valkyrie Logo

Uriah's first design
This week I thought i would give some credit where credit is due. As has been talked about the Valkyrie has some founders that had faith in the idea and were willing to put up some cash to get it going. One of the founders is Uriah Walker.

Uriah basically took it upon his self to start designing the logo and I think he did an excellent job. We discussed a few things but it was all his doing.

His first design was good and I didn't think it could get better but he wasn't happy so he made a few changes.

Picture
By his second design and then the final i really loved where he was going with it. I wish i had half his talent for artwork but I will have to settle for my mechanical abilities. 

His design pulls all that I think is important in the Valkyrie including the 800 series bolt face. It also grabs the eye and will give good brand recognition in my opinion.

So lets all give Uriah a big hand for a great job with the 7mm Valkyrie AR logo.

7mm Valkyrie How  it came to be

6/17/2015

By Bruce Finnegan

This week I will go over how the 7mm Valkyrie came to be.

The Valkyrie is a group project from 15 of us on Facebook. I originally asked on the 68forum what calibers would be a good idea to put in the 270AR case the 2 overwhelming choices were .25 and 7mm. I did the 25 first with the .257 Bobcat and the results were way better than expected. I did some research and there really wasn't very many 7mm for the AR15. So i decided to give it a go. I wanted this round to be one of the ultimate hunting rounds for the AR15.

I did a rough design in Quick Design and made a couple dummy rounds. Quick load predictions were very respectable. I then started talking with Craig Black on FB about my ideas. He was really interested in the 7mm also. By now i had the first design pretty much down. Craig had the idea to go about sourcing funds for the reamers by bringing it up on fb and see if there were 15 or so guys willing to put up 100 each to get it rolling faster. We posted the idea and predictions and in no time we had the slots filled.

We called these guys the founders. The founders gave ideas and input. We all agreed the round was going to be geared toward hunting and one of the most powerful rounds to fit in the ar15 for hunting. Some of the founders sent sample bullets for me to put in dummy rounds. By now I was finding I needed to make a few changes to the case to allow it to run more bullets so I pushed the shoulder back some and trimmed the neck .010. This left about 42.5 grains case capacity and velocity predictions were still very good. More input was given and we decided to run with it.

Reamers were ordered and the first test blank was ordered from X-Caliber barrels. When the reamers arrived my smith and I chambered the first 7mm Valkyrie in a savage. It is easier and faster to build a savage barrel than the AR barrels. I made this one 26" because my plan was when done testing I would deep chamber it to fit the full length 6.5x47 Lapua case just necked up. In the mean time i also ordered 3 profiled blanks from X-Caliber a 24" semi bull for me and a 16.5 and 20" for Rick to start testing.

By now the data I was getting from the savage was meeting the predictions and surpassing some of them. I was finding it was going to shoot the 160 class of bullets very well which was a happy surprise because it was designed around the 140's. The AR barrels came in and were chambered more testing and we decided the chamber was good as it stands 10 more barrels were ordered for the founders that wanted to be testers and that brings us up to now. The tester barrels are shipping this week a little behind schedule but better late than never.

That is how The Valkyrie or as we call it the 7 VAR came to be. I have big hopes of it catching on but I am realistic that making this wildcat is a little harder than some so not everyone will want the challenge or work. I think of it this way for performance in anything you have to pay to play as in we pay some time to make the brass for it but when done we have a round that is a legitimate big game round to 500 yards or farther in an AR15 platform. With 140 and 160 class bullets it has 1000 ftlbs of engery to 750 yards so medium and under game caliber to 750 yards. 

thank you for reading

My Ultimate AR-15 Build

Here is my ultimate AR15 build. Since the 7mm Valkyrie is my second wildcat I have designed I wanted to build a rifle to show it off. There was a lot of behind the scenes work to get all the parts.

The first part was the custom engraved Side charging upper from Eisenach Arms with their Nib carrier and custom 7VAR laser engraved charge knob.  Jared and Josh Eisenach are in the Valkyrie founders group so I asked them if they could get the logos on the uppers and they were all for it. In a matter of weeks they put together a group buy and many of the founders got the custom uppers. A big thanks to both of them.


Picture

Next custom part that I just received is the billet lower receiver from Brandon Sneed at www.southtexasarms.net Brandon was putting on a group buy for his lowers at a great price so I contacted him to see if I could get the logo engraved on the lower and he said sure. Customer service like this is awesome and it is great there are 2 companies that will cater to us crazy guys that build guns. I ordered 2 of the lowers from Brandon and will be assembling a twin to this rifle in black with a tungsten coated barrel to sell in a few months.


Picture

The rest of the rifle is a collection of parts that I just like. Here is a list:

24” 4140 cmv X-Caliber barrel rifle gas in 7mm Valkyrie AR   manganese phosphate by my local smith, semi bull with .975 to gas block, .936 gas block and .812 to the muzzle not light but it is a shooter.

17” rail – from Johnathan Whitney

Syrac adjustable gas block with rifle gas tube

Cmmg lower parts kit from Brandon 

Geissele 2 Stage (G2S) Trigger

Ergo grip

Rifle buffer tube, spring and buffer from Brownells

Luth AR stock

Economy charge handle to fill the spot.

All Cerekote in Burnt Bronze.
I think all the parts came together vary well I have a few little accents I want to put on like black rail covers just to make things pop and a sling of some sort just haven't decided.
