Why are all the production ARs' coming with 1/7 to 1/9 twist bbl's.
Wasn't the .22 cal high velocity load originally intended to have a slower twist.
The Bushy Varmint special I recently bought had a 1/8 and the RRA Car Elite that I just got has a 1/8(both in Stainless). I sold the Varmint upper and intent to get another upper/bbl but I was going to get it set up with a slower twist rate and strickly for 52 to 55 gr loads.
The last 22-250 Bull bbl bolt gun I had came with a 26 in bbl in 1/14(I think
hinking.gif) and shot everything from 50 to 55 grs great(except the Nosler Ballistic tip
heavyI know there is a sizeable difference in the velocities between the 22-250(around 3700 with handloads) and the .223's.
I intend to experiment with heavier bullets in the RRA but for a .223 varmint gun and slower velocities, will the 1/9 stabilize and shoot the lighter bullets CONSISTENTLY or would it still be better to go with a slower twist ???
