Re: 300 RUM and VLD's velocity ?
My 300 RUM with a bunch of different bullets liked the 200gr bullets in every brand. I settled on AccuBonds for a better hunting bullet than Match Kings or Game Kings or Bergers. It shot Retumbo the best. H-1000 shot good with one load but the Retumbo shot good with a wide charge range, and the sweet spot was almost a single hole. The 338RUM likes Retumbo also so thats great, I can buy mass amounts of the same powder. They are both great calibers, I had the 300 barrel threaded and put on a Miculek brake, the lighter weight 338 RUM had a clamshell brake made for it and they sure are fun to shoot.
