Getting ready to order a new barrel with a 1:12 twist. I was very surprised that they are not readily available. All my .223 shooting is done with 50gr slugs at 3400fps or faster, guess I'm addicted to the red mist. 1:9 barrels just don't give the same results, I've tried, groups run double to tripple the size of my single shots with 1:12 twist. No 62 gr is not an option, slow, rainbow trajectory, little expansion. I shoot single shots along side of 1:9,8 & 7 AR's and am not in the least impressed with how they shoot with heavy slugs on groundhogs. Simple fact is all I'll ever shoot the AR at is groundhogs and paper so my AR is getting set up for a proper varmint load.

 

Just wondering if anyone has played with 1:12 AR's in the modern era. Back in the 70's 1:12 was all there was, I shot a lot of 55gr out of M-16's as one of Uncle Sam's Misguided Children out to 500yds and remember better results then I'm getting with My current AR, of course the targets were bigger and I'm a lot older. . .

What configuration barrel are you looking for 20/24 heavy? Were the 1:9 barrels that weren't performing chrome lined? 5.56 or .223 chambers? 50gr in a 1:9 I agree is marginal. When you find one please post as I'm interested also.

do you think that maybe your single shot 1/12 .223's are more inherently accurate then your ars? Maybe the stocks are better suited for optics and your getting a better cheek weld? maybe a better trigger on the single shots? I know for a fact I have head issues when im shooting a semi automatic and cant seem to slow myself down as I would with a bolt action or single shot so my groups tend to be bigger with a semi auto. Service rifle barrels are usually 1/7's or 1/8's and that market demands accuracy, although they are shooting heavier projectiles then you.

It's shooting OK for an 16" 1:9 auto but I want to get it under an inch. No I don't ever think it will equal the single shots. But It won't be used like a 9lb single shot, more of a walking around the farm rig for when I want more power then a rimfire. White Oak Armament will make a 1:12 barrel. Already have a 3lb Timney trigger installed. Like the 10/22's and the Encore this is one of those rifles that is to easy to change into something else.

1/12 is more accurate in the majority of cases if you are using lighter projectiles. I shoot 1/12 every time I go out, but usually 1/9 and/or 1/7 also. I do not buy any more 1/12 stuff. But I will buy a 1/12 barrel to replace the almost-shot-out barrel I have in the upper with that twist.
