Long Range Hunting AR

I'm looking to build a long range rifle on the AR platform. I'm looking to keep it as light as possible, but need to be able to reach out there and touch something. So, what do you guys recommend for being able to take elk over 600+? Can I do it on an AR-15 platform or do I need to use the AR-10 platform? Also what caliber?

thanks!

Re: Long Range Hunting AR

You will be hard pressed to find a round that will deliver the kind of energy required at that range in an AR15 lower! Your going to have to step it up to something bigger, Armilite makes what you want in 300 RSAUM. Or there is another option in 300 win mag but its not on the market yet and its going to run 4 times as much.

If your happy with the 308 winchester or 260 rem there are a lot of options for them as well.

Re: Long Range Hunting AR

you may want to take a look at the Noreen semi-auto rifles. these aren't going to be light rifles. and get ready to break the piggy!

you may be ok with the .260/.308/7-08 or even a .243 on the AR-10. on the AR-15 the WSSM calibers might work BUT you're going to have mag length issues on both platforms with heavier bullets suitable for that kind of distance and still perform on elk. you definitely won't be overgunned with these platforms!

GAP is suggesting creedmore loads (6 or 6.5) out of their AR platforms. the case allows for a longer bullet to fit in a mag.

Thanks for the responses!

So if I'm understanding this correctly the WSSM will work on the AR 15 platform? However these might be a little small for elk at longer ranges. So, I would be better off looking toward the AR 10. As far as the AR 10 goes am I better of with the .308 or .260 for big game?

I have no first hand knowledge of the wssm or anything bigger than a 264 lbc or 30 rem on the smaller platform. My advice but an LMT MWS.

Re: Long Range Hunting AR

I'll tell you strait up that the WSSM, while easily the best "long distance" performer in the AR15 platform, is still going to be a bit under gunned on Elk at that "middle distance" you mentioned.
I send my 105 Amax at 3200 +/- and while I wouldn't hesitate to take deer with it...IMO, that's a little bit light for Elk at the range you're looking.
Even the 300 OSSM (Olympic Arms' WSSM in .30 cal) which boasts 30-06 velocities with 150gr bullets... wouldn't be my first choice.

At that range, on that game...the 300SAUM is my absolute first choice, and that's exactly why I bought/assembled mine. However. Neither Armalite, nor DPMS are still making them, and the guys that are...are going to be back ordered 9-12 months.

If weight is a concern, get in better shape or start looking for a different rifle. Nothing about an AR10 style rifle, built specifically for "long" range hunting is going to be light weight.
You're not going to be taking your 600+ yd shot off hand, and you're not going to be pressed for time. Get a comfortable pack, or double shoulder sling. It makes a 20lb rifle feel like 10lbs.
For long range, weight should not be the primary concern.

When it comes to hunting, energy delivery comes down to mass and velocity. How accurately and fast can you send the heaviest bullet.
You're going to need case capacity and barrel length.
If you want to hunt with it at "long" range..then that's one of the few times I would suggest a 24" barrel.
18-20 is fine for punching paper and hitting steel...but for taking critters, you're going to want the added velocity. Especially if said critter is an Elk at 600+

Re: Long Range Hunting AR

I love my semi automatic rifles. With that being said, if you are looking for a rifle and cartridge combination that will reliably kill elk at 600 yards, I think with very few (and extremely expensive) exceptions you best bet is a bolt gun.
