Reply With QuoteThe standard is 10 but I would ask Pac-Nor. I use a 10 and 12 and the 5R guys are using an 11.25 or 11.75 maybe.
Hi guys I have a question before I drop the money on a new barrel. I know this question has been run over by a train. I am wanting to get a pac nor straight tube 20" .308 barrel. I will be shooting hand loads in the 168-175 gr match bullets. What twist is the best for these loads.

All my 30 cals are 12 twist, I would not have it any other way.

RUMs are like woman in Stiletto heals, you know they are going to put you in the poor house, but that has never stopped anyone from pursuing them.
JBM has a very nice free ballistic calculator. Use the reference tables for bullet length and then run the calc.
I'm a firm believer in the theory that if it bleeds, I can kill it.
