    I have a Bushmaster Varminter .223 with 24", nice trigger etc. What I want to do is get a .243 upper and barrel of similar length and go deer hunting with it. In WI and ND we can use a centefire .22 cal, but some of the shots in ND can be a little far for a .223. Does anybody have any experience with a .243 AR rifle? Any recommendations for barrel manufacturer? DPMS makes a .243 barrel, anyone else?

    Your easiest option here would be a 6x45mm, simply a 5.56mm necked up to take .243 bullets. Plenty of load data available, decent performance, and readily available (and inexpensive) brass for reforming. This is a simple rebarreling, nothing more. Beyond that, there are several other options, all of which require more work, much more costly brass, and more effort on your part. I've had a 6x45, and it was a decent combination. I've seen a number of the other guns, particularly the 6mm PPC set up in ARs for competition use, but they do tend to be a lot more finicky.

    If you want an actual .243 Win (I wasn't quite clear on this from your post) then you're looking at a larger platform, such as the AR-10. What did you want to do with this? That should be the final determining factor in how you set it up.

    yep, the 243 is too long for the AR-15, so you must go with the AR-10 platform (308 win. length action) not only is an AR-10 400 dollars higher than the AR-15, its also 3-4 pounds heavier.
    However, you can call or email mike milli of bemenji mn, he's an AR smith, does good work very reasonable, he'll build you an upper for the AR-15 chambered in 243 WSSM, and it'll fill your 243 needs in a lighter weight cheaper rifle. I've had one of mikes uppers for several years (25 wssm) and its the most firepower you can get in the AR-15

    Another possible option, that I think will fit your current platform is Remingtons new 30 AR cartridge. Its a 30 cal that is getting dang good ballistics for a ar 15 frame 30 cal, about 80% of full power 308. That would be a much better option than 22 or 24 calibers for deer. Just my lowly opinion of course: 308

    6.5 Grendel gets my vote. I've built a couple on AR's and a CZ 527 Carbine and it's a good round. 120gr Nosler BT's at 2550 or so is plenty good for deer. 100gr bt's are probably a little flatter shooting. You can still buy the Wolf Gold for $12 a box through Midway...not to bad.

    Pick up a DPMS upper in 6.8 SPC.

    There are many other manufacturers that offer a 6.8, but it's hard to beat DPMS in the bang for the buck category. I am building two 6.8 SPC ARs on Rock River lowers (plus a 5.7 on a RR lower), right now. Don't have all the parts yet, so I can't say. But I did have a 6.8 SPC barrel made for my TC. It has more recoil than I expected, but it sure is fun to shoot (too much recoil for a small kid, but not an adult).

    80 % of a 308 win. is the 7.62x39 russian or the 30/30 win.

    Yes, I was talking about .243 WIN. I want a caliber that I can buy off the shelf ammo, no custom stuff. Maybe I will just stick with the trusty ol' Win 94 30-30 or get a Browning X-bolt in 270 WSM.

    I'll second the 6.8 SPC. It will drop right on your .223 lower. I don't know about smaller towns but ammo can be had at places like Bass Pro Shops or Cabelas. I have a Rock River Arms upper on order for deer hunting right now. Figure on putting a red dot sight on it for still hunting and deer drives. Even out of a 16" barrel it has fairly impressive ballistics on the AR platform. The 6.5 Grendel is a proprietary round and really suffers when used with a short barrel. Unless you are talking long range shooting, it offers nothing that the 6.8 SPC doesn't. (I would like to have one with about a 22" barrel though, but kind of pricy.)
    The 7.62x39 is certainly another option. Not quite as flat shooting but would be great on deer at moderate range.

    6.5 grendel Wolf Gold ammo 120gr sp's are still $12 a box of 20 thru Midway... Cheap enough to buy a bunch. Out of my 22" Grendel they shot 1 1/4" or so. Loads with the 120gr Nosler's and Sierra's went sub 3/4 MOA. I built my Grendel off a worn-out 30" Krieger 6.5-284 barrel. It's amazing how GOOD that last 24 inches of barrel looks like after you trim 6" off the chamber end and one at the muzzle, and all for $50.

    If you need to use the same lower I´d take 6.5 Grendel but take note what sambo3006 said previously about the barrel lengths.

    IMO best solution would be to buy a new gun. DPMS has various models for example in .243 Win, .260 Rem and .308 Win calibers. Armalite makes AR-10 in .308 Win.
