which caliber ar 15

[snox801]

So hear is the deal been looking at an ar 10 in 243. But found a steal on a 15. So question, what would be the closest thing to a 243 I could get barreled in an ar15 lower. Thanks

.243 wssm, .25 wssm, 6.5 Grendel or 6.8 spc. But why stop there 30 wssm, .300 whisper, .50 Beowulf. Not being a smart alec but there are so many chices for different distances, hunts etc....gun)

If distance is your thing go with the 6.5 Grendel (obviously my personal favorite) but 6.8 spc ll is good out to 400 yards and is actually better within 100 yards, but after 100 yards the Grendel dominates out past 1000 yards. But if you go with the AR 10 Type platform go with the .308, its a much better round and has lots more ammo to pick from.

6x45 perhaps? It will still be a 243 bullet and is everything a 223 wants to be.

If you want something close to a .243, then the 243WSSM is your best bet (in a 6mm bullet)
The 6mmARTurbo40Imp is very close. but still nearly 150-250 fps slower than the WSSM
The .243 WSSM and the 25 WSSM are your two best bets for long range. (and I do not mean inside 1000yds) You may be restricted to bullets that have a max of about 105gr but that tends to not be a problem for people looking to hunt with it.

I've seen guys shoot the 105 Amax with excelent results at an OAL of 2.26...but I've gotten best results by modifying my Pmags and shooting with an OAL of 2.375.

I was shooting 105 Amax at around 3165 before I pulled the barrel for a faster twist. Still waiting for it to show up.

Hey thanks guys. I should mention it will be a shorter range 300 yards tops gun for hunting. Any thoughts on the 25wssm, I already have 110 accubonds for my weatherby what do you think.

 

[steelshooter]

I had a m70 in 25wssm. I sold it due to poor accuracy but velocity figures were quite impressive, on par with the 2506.

The 25 wssm is the cousin to the 25.06 which is a very good choice however the 25 wssm is prone to misfeeding from magazine (especially AR's) and Olympic Arms is the only Manufacture of complete uppers. I also believe ammo choice is limited unless you do the reloads. Im not purposely ragging the 25 wssm because I to would like one but if 300 yards is your maximum distance you might want to consider the 6.8 spc. Ammos plentiful and its good out to 400 yards (The 6.5 Grendel is very similar but while the 6.8 spc shines inside 100 yards to 300 yards the Grendel excels out past 400 yards.) Bottomline is that everyone mentioned are good choices.gun)

If 300 is the max, I'd probably suggest the 6.8 as well.
However, there are a couple misleading points made here, and I'm sure it's simply due to misinformation or limited experience.

I've seen no users have issues with feeding when they were using a properly built or modified magazine and as with ALL magazine makers...occasionally, a lemon gets out.
Olympic Arms sells them, Mike from Dedicated Technologies makes his using GI mags with Magpul self leveling followers, Carl from Accuracy Systems makes his, and I also make them from P-Mags which (IMHO) is superior to all of them.

FACTORY Ammo choices may be limited, but for the intended purpose, the options available, are almost NEVER out of stock, and will handle the job just fine. Since the OP mentions having 110 Accubnds on hand, that suggests a reloader, and so there should be ZERO trouble finding a nice load to take game with.

The nice thing about choosing the 25WSSM, is that IF YOU CHOOSE TO...you can bang steel, punch paper and take game in excess of 800 with relative ease, as long as you're confident at those ranges.
I've taken my 243WSSM out to 1150 with relative ease and when my faster twist barrel shows up...I won't hesitate taking shots at coyotes at that range. Might be a bit far for big game, but predators wouldn't stand a chance.

NOW, as for a place to actually get one. You WERE limited to three options...all of which use parts supplied by Olympic.
Olympic Arms themselves and their factory uppers.
Mike at Dtec builds scary accurate uppers or rifles but they come with a serious wait time and a reasonable price.
Carl at Accuracy Systems also builds a scary accurate upper or rifle, but it's about the opposite. Much less of a weight, but a bit more expensive.

The last option is a bit new and I don't have ANY experience with them. It's JARD Inc who built a carrier and bolt of their own design and now offers 243 WSSM, 25 WSSM & proprietary Jard 7mm WSSM. May be worth doing some more research on those guys since they are pretty new to the game.

I'll admit to ltd experience with the 25wssm but I have alot of experience with the 25.06 which is why im interested in the 25wssm. So the other manufacturers are very reliable? Thats nice to know.

 

[snox801]

Ok how does this sound, I think ill settle on either 243-223 or 25-223. I would like some input on what you guys think. I want to hunt deer and pigs close range. So I would like a 25 cal but think the 110 is to long. Or the 95 grain 243. I wonder if I could just trim the case back a little further. I know ill loose fps but I think i could still stay above 2400 fps. What do u think

Is it close range for the deer, too? Say, are you keeping it under 200yds?

.458 SOCOM is works well on deer, and would slaughter hogs. Basically an AR-15 version of a 45-70 Govt.

I love mine!

 

[bronco]

I think the 6x45 - 243/223, by whatever name would be the ticket. I would start with 90AB or 85PT. Both should run above 2800fps and give you the necessary penetration for shooting hogs.

 

[snox801]

Bronco, that is exactly what. I was thinking with the nosler, Or even sst I was just pondering the idea of using 25 cal 110 accubond so I could buy one large box of bullets for that and my 257, But I think there is more work than just necking up the 223. I'm also not sure what the velocity would be after I trimmed the case back far enough to make the 110 fit.
