Re: need barrel advice????
I just checked out several factory rifles chambered in that caliber, and nearly all had a 22" barrel. One was 18 1/2", and even an ackley improved was only 24". As far as twist it looks like 1 in 12 is the best option, but I would check out some barrel manufacturers sights for more info. Lilja probably has some info. in the FAQ section of their sight.
