It looks like I should be ordering my HART barrel at the end of May. I would like to here more than 1 opinion on what rate of twist? Would it be worth the extra money to just send my rifle to HART and have them figure out where the rifling lands should be and what rate of twist is best for long range, shooting 210gr. berger VLD's? It will probably cost quite a bit more, but will it make a big difference? If not, what is the best way for me to tell HART where the Rifling lands should start? Since I don't care about the rounds fitting in the magazine, should I just load the bullets as far out as possible and send them the COAL? I'm sorry about all of the questions, but this is my first custom built gun and I don't have allot of money to do things twice!
TacticalHits, I am thinking a 1-11.5 or 1-12 twist will be perfect. I would ask Kirby Allen or Goodgrouper. They are both very knowledgable about this stuff and I would ask their opinion on twist. The 208grn A-Max, 210 VLD and MK, should work really well with the 1-11.5 or 1-12 twist. You could call Hart and ask them too, however, I am thinking Kirby Allen is the guy you want to answer this questions. What ever he says, I would listen and follow his recommendations.
TacticalHits, JWP475 is right about the 1-10 twist. You can't go with that twist with the .30cal. I just remeber someone telling me if you're going to use bullets from 190 to 210, the 1-11.5 or 1-12 twist would work best. However, the 1-10 would allow you to shoot the 220 and 240grn bullets, but I think these bullets wont work as well out of the 300WSM. I would seriously post something to Kirby and take his advise.
