Guys I give you the .277 Wolverine. This is a new round formed from 5.56 brass necked up to .277/6.8 and trimmed to 1.535 developed by Mad Dog Weapon Systems (MDWS) who is offering barrels and custom Hornady dies. I have been following it's development on the 68Forums for a while now and decided to put a 10.5'' barrel on order and obviously a set of the Hornady dies. The 16'' barrels are already in the hands of some customers and the performance is looking great. I'll post links to info and user findings for anyone that is interested until I can get my barrel and post my own testing. This will be my first cat and first AR pistol build, so far it's been a blast. More to follow over the next few weeks.

Specs wise this .277 wolverine looks very close to the 6.8 numbers..

Whats the benefit here of a one off barrel? Just curious..

Who is producing barrels?

Barrels are being supplied by ARPerfomance for the 16" and Mcgowen Precision is supplying a 8.2", 10.5", and 18" option as well right now.

For me the advantage was I was already planning a pistol build and collecting parts for a 5.56 or .300 and I already reload for 6.8 spc. I like the fact that i can get that little bit more bullet weight and energy down range without sacrificing quit as much vel. as I would with the .300. I've always wanted to play around with a wildcat and being this was uncharted territory it seemed a fun project. For anyone else it's really to each his own I guess but I do think my particular setup will make a helluva little fast brush gun for stalking deer and pigs. Plus it just makes for a sexy looking little round I think.

Meet the little family. A little comparison for ya. The empty caseings from left to right 5.56, .277 WLV, 6.8 spc
The loaded rounds from left to right 120gr. SST 6.8, 90gr. Gold Dot .277 WLV, 53gr. V-Max 5.56

Oh its all good, hope i didnt come off abrasive, was just honestly curious..

I have looked up a little on this cartridge thru those links, looks like a cool wildcat..You will have to let us know how it goes, and ballistic/chrono numbers...

You didn't come off abrasive at all mustang. Sorry if I did with my response, didn't mean to. This truth is though until I can get my hands on it and get my own testing going it really is just a novelty right now, however if I can reproduce what others have found with it which is close to my 6.8 with the recoil of a hot 5.56 then I think it will be a jam up little round especially for the wife. I really want to eventually do some suppressed testing to see if it can come close to the BLK suppressed performance, that could go either way I think.

Well I've already been piecing this thing together for a min. so not a whole lotta pics of little parts to ration out but here's the complete lower. Also unlike the 6.8 I can utilize P-mags with this.

I just found them myself this year, this was the first one I bought and after handling it my dad also bought one. The finish and machining are great and I really like the style and feel. The only drawback I have found if you can call it that is the tolerances are on the tight side which just makes for really good and tight fit to any of my uppers but out of 3 tried I did have to polish the takedown pins on one due to the rear pin was just uber tight.

Thanks UW, yep still waitin. It's killin me im ready to shoot! There's quite a few of the 16'' scout profiles getting out there now, some of their independent tests are showing some nice numbers, 90gr 2560fps, 110 2500fps, all the way up to 120gr 2226fps just to through out a few and it's still early yet.

I'm headed to the 68forums southeast shoot near Alto, GA the 6th so MDWS contacted me to let know it's gonna be really close on getting my barrel in time for the shoot. So he offered to send me his 8.2'' complete upper on loan to take to the shoot and develop loads until I get my barrel. I've only taken it out one time but so far I'm really impressed. Done a quick ballistic test that I wanted to share. 90gr Gold Dot at 100yds 8.2'' barrel. Slug still weighed 85.7grs

How reliably does she feed with PMags?

GaSwamper
31 August 2014, 10:26
UW she feeds great, not a single hiccup after about 100rnds so far. I even loaded some 110 Barnes TSX long and just knew they were gone give me trouble but didn't. Also noticed even light loads will cycle good, only one set didn't lock back after last round but these were really early in some load development. So far reliability gets the thumbs up for dependable.

Just got back from the 68Forums Southeast shoot in north Ga this weekend and it was a blast. The 8.2 Wolvie demo I took performed great and put a lot of smiles on some faces. Another member, that I recently found out is also a member here brought a 16'' scout Wolverine that he actually won the 100yd free arm one shot challenge to take home a new 16'' ARP 6.8 barrel. I competed with my 6.8 since it was open to the long guns only and got beat by the Wolvie ( by only inches in my defense) and was 3rd out of 14. I also came in third in the 3gun shoot with a borrowed Glock and completely skipped a shotgun target for a 5 sec. deduction. The WLV ate up the steel at 100yds from prone and off hand, prone I was able to put rounds on a 3'' pink steel deemed the pink lady at will, wrapped it around the beam. We got some good vids and pics comin, hopefully I get us some links soon. Now to send the 8'' upper back home so maybe we can get back on track with the 10.5'' barrel.

Hey that's me you're talking about lol. I've been a lucky guy here lately. First the 308 build parts and then the barrel this past weekend. I've been told to take the horseshoe out of my A$$. Yea the WLV stole the show that's for sure. But hey sometime all it takes is a few inches...[:D]

Also the WLV did pretty good at the 300m mark as well. It was still ringing steel at that distance. Drop was not horrible, I'm no expert calculating it but it was just a little over 2 marks on my viper 6.5-20x44 dead hold bdc scope.

I've personally been getting 2800 fps average with a 90gd and 1680 powder with .7" grouping at 100yds... I have also been getting 2675 avg from a 100gr Accubond with MOA accuracy at 100 yds using the same powder... Ive got .4" grouping with 22.0gr of RE7 that still pushes a 90gr GD to well over 2600fps

GaSwamper
17 September 2014, 18:18
I know the numbers are on the heels of the 6.8 in the 16" barrel with less recoil. The 8.2" was naturally a little snappy with only a linier comp, but nature of the super short beast, nothing too bad though. I was getting about 2300fps out of 90gr. Gold dots in the 8.2" but as you can see in the pics the gold dot loved this speed at 100yds. The 8.2 was fun as hell but I think the 10.5 I have coming will be great for this round.

100gr. Accubonds and 1680 really seem to shine across the board. I could actually get better numbers with these vs. The 90s without overgasing. But gotta luv what those cheap gold dots do to things they hit, definite man stoppers.

Well the man himself, welcome. Note that when the 8.2 was in my possession at was at the generosity of MDWS, I did not push any loads because quite simply it was not my upper to do so with. If any mistake on my part would have happened (yes they can happen)I wouldn't have been able to forgive myself. I stayed in safe zones with my loads, but 2400fps would definitely have been attainable. I expect the 10.5 " to give a nice boost.

I'm glad you enjoyed it, and thanks for providing the opportunity for others to shoot it as well. Your 10.5" should get to about 2500 safely with a 90GD if you play with some different powders.

Quick range test today before the afternoon bowhunt. Thrilled, numbers are on track and was shocked at a 100yd group I was able to pull off after a sight in at 50yds. This is a new virgin barrel btw. For a 10.5'' I really wasn't expecting it this tight. Rounds tested were as follows.
90gr GD, 22.8gr AA1680, WSR primers
Muzz. Vel.
2478
2476

Testing update. Several rounds im still developing but these two are done for now and happy with the results.
90gr Gold Dot, 23.0gr AA1680, OAL-2.14, Muzzle Vel. Av.- 2568fps
95gr TTSX 22.3gr AA1680, OAL-2.23, Muzzle Vel. Av.- 2539fps
The gold dots could be pushed faster but I like the 100yd expansion at this speed, the last test yielded a quarter size slug and retained 85gr of 90gr.. I fear any faster would fragment. The 95's also gave me .5'' grouping at 100yds.

Sounds interesting have you conducted and test fires? If not how far out for those?

I have inquired with JB's Firearms (JBFA) who is making the ammo and he seemed to think he can get it out to market in a couple weeks. JB's produces .300 BLK and 5.56 already and I'm sure more. I have purchased .277 WLV brass from him that was excellent quality. When the ammo hits the market I'll def. be testing out.

That's good stuff right there. You have a very nice hunting load.
