Hey guys. I am planning to use boolits in my Marlin Glenfield 30 for deer this year. This rifle has a 20" barrel with what looks like micro groove rifling, it doesn't say so on the barrel. I'm thinking a gas check 150 grain at 2,000 fps is what I need since this is pretty close to the 150 grain j-word slug at 2150 fps I've always used. Would the Lee 150 grain GC flat point be a good choice? What about powders? I use Varget in my j-word loads but it seems boolits would prefer something else. How about Accurate 5744 or Hodgdon 4895? These two seem to be quite favored for boolits in leverguns.
