Does anyone have any experience with Hart barrels? I sent my 700 sps there for rebarrelling and getting a muzzle brake installed. Any ideas in what twist and length that I should go with? I'm shooting a 18 grain bullet. It's a 300 RUM. I'm also putting a new trigger in it what would be your first choice of trigger?
A 1:10 would be ok unless you reload and plan on shooting out to great range. 800 +. Then go with a 1:8. That would give you the ability to load the full range of bullets. Serria has a 240gr bullet.
But you really need only a 1:10 if staying with a 180 and 24" should really be the shortest length.
