OK so here's my dilema. I'm wanting to build a new AR 15. But not in .223/5.56. I have a Model 788 in .223 a 600 in .222 and a savage model 10 predator in .223 so I don't need another. This will be used for killing paper varmits and maybe deer and antelope. So I was thinking a .243wssm from dtec or olimpic arms or a 6mm turbo 40? If I member right both have similar balistics. So what would you go with?

The 243 or 25 WSSM would be a great choice, leaning to the 243 if double duty for varmints and deer/goats. No forming of brass or expensive dies. For strictly deer sized game, a 6.8 SPC would be nice.

How about a 260? That would be very effective for what you want to do, or just a plain old 243 Winny would do the trick also. 6.5 Grendal could be fun too. Just thought I would broaden the spectrum. OOOOOH, the 338 Federal (338-08) could be interesting. I bet your really confused now. Glad I could help!!:D

Most of those are AR-10 chamberings. Requires a much larger and heavier rifle.

Oh, well you could use the same lower and put an AR10 upper on it... right? I don't know very much about AR's other than the M16A2 I used in the service. I am a bolt gun man. The reason being is that semi auto's are illegal in PA to use for hunting. Not much reason to own one. For the money I can build nice rifles.

Well that just sucks! Do they make an upper for the AR10 that will allow a guy to shoot 223 if he doesn't feel the need to rip through a ton of powder and more expensive bullets? Or are we still at square one? Sorry for all the questions. I don't post on AR's for obvious reasons.

Never heard of that. I'm sure it could be done, but I don't think AR-10s are popular enough to merit the design expense for a manufacturer. Maybe a one-off deal, but in general, no.

man, If it were leagal up here in Canada I would have an AR15 in .243 WSSM. That just sounds like the sweetest little rig. I recal a video on here (maybe) where a guy was shooting just that. Not to many things that arent heavy bolt guns gets me excited, that idea does.

I have a couple of 6AR Turbo 40 degree uppers that shoot very well. I have one with an 16" barrel and one with a 28" barrel. The 28" is for highpower rifle competition shooting. Shot the 28" yesterday at 600 yards with a scope to check some loads out. All (105 and 107 bullets and Reloader 15 powder) grouped well, but one load with 107 SMK shot 4 shots into around 1 1/2" with the the fifth hole being about 6" to the left. Had some switching wind which may account for the one out of the group. I was not watching the wind just trying to shoot fast.

If the 6mm bullets will do what you need I think the 6AR family would be a good choice and can be had much quicker than one of the WSSM's.

I have a 25 WSSM on order from DTECH that has around a 7 month delivery, The 25 caliber has some heavier bullet options if you are interested in that. I plan to use it for pigs and deer. The pigs is why I am interested in something larger than 6mm.

Good luck. Ken

I have a 25 wssm upper the only thing i don't like is seating the bullet so far in the case to get to fit the mag. even factory ammo to long plastic tips get bent lead tips get flat so I seat the bullets deep so the ammo dosn't ride both ends of the mag.

What about the 6.5 Grendel? I am considering it with a bull barrel upper. I think it will work with a standard 223 lower. Just need upper, new bolt, and magazine.
