Poll: What Would be Your Next AR15 Caliber?

[Ura-Ki]

I have been considering a long action cal version of the AR platform! I really love the old wildcat 6.5/06 or the old 6.5/55 swed. A 7 mm rem mag might also be a really nice build!

If you go 7mm you'll find that ball ammo is more difficult to find; as for me, in the current political climate, I would take the money and spend it on heavier weight bullets for the 556, match grade triggers for my current rifles, improved optics or perhaps a Pro-shooter's course.

I am just about finished with my little CAR 15 build. I specifically went with the new M-4 pattern barrel in a 1/7 twist WYLDE chamber to take advantage of the new M851 ammo coming on line! Its a shooter now and can handle up to 82 grain hunting loads remarkably well!

An AR15 in 10 mm would be a pretty nice performer! Would make a really nice hog rifle!

Why would anyone want a .300 BLK? I can shoot my suppressed 9MM carbines for a fraction of the cost with factory ammo.

I wanted a medium range .308 and don't want a 7.62x39. The 300 BLK works in the AR platform and is both fun to build and shoot. Love reloading now that it is beyond 'wildcat'. Ammo & supplies have really dropped.
Many of us do not shoot 300 BLK suppressed with all the current stamp hassles. Let 'er crack!

M855A1 or something else?

The Military has a new 77 grain coming out I think its designated M851

You mean the Mk262 ammo they've had for some time now?

 

[Ura-Ki]

I am not really 100% sure on this load. I hear its a 77 grain steel tipped load and I hear its ether M855A1 or a re-designate to M851 to make it less confusing which loading you get!

 

[Boboclown]

M855A1 is a steel tip penetrator on top of a copper core. Still 62 grain. Only 77 grain military (our military anyways) ammo I heard of is the Mk262 ammo.

It was news to me as well. My cousin is still active army and says they have been working with a "new" steel tipped 77 gr load! He says it has issues with the tips wearing feed ramps and has to be used with new gen P-MAGS or modified mag followers on older mags! I cannot find any info on this or if it really is a new load or not. He does say its pretty much a done deal and will start being issued this very soon as a standard loading!

 

[Boboclown]

Only reason to replace a follower on an old mag is if the follower is worn out or you want an anti-tilt follower. Ammo won't change what magazine you can or can't use. Except the really heavy round that's too big for a magazine anyways.

As for the 77 grain steel tip, I doubt it.

Again, I'm not sure of this. As far as I am concerned, any ammo I can reliably use is the goal! I will ask for specifics from my cousin and find out what he is referring to! I have never had any problems with ammo feeding or wearing feed ramps so that is new to me as well! Also I have a big stack of old mil spec mags with green followers and have never had issues with those ether!

 

[Boboclown]

He probably meant the M855A1 and mixed up the weight with the Mk262.

I'm kind of thinking the same thing! By the way, thank you again for the advice on the CAR build, it really is turning out nice! Just having it ceracoated now!

No problem.

My short list of desired alternative calibers is 25-45 sharps and a 458 socom. One fast and long range, one heavy and short range.

.375SOCOM is a bit intriguing to me at this point.

While I am a bit biased. I would build a 6.5 Grendel.
Reasons. I can do with my 20"AR15 what anyone can do with their 308 in AR10 (with the possible exception of blowing apart a cement wall) and one hell of a lot more comfortably and easily. With much better wind and drop long range than an AR10. I've shot them side by side and I sold my DPMS SASS. My friend is selling his also and having me build him a Grendel. Ammo is sold at Bi mart and there are dozens of factory loading for it.
My second choice would be a 300blk in a pistol with a suppressor. Mainly for home defense.

I do like what I've been reading about the Grendel. Sounds like a nice round.
