I am working up a load of 300gr Hornady JHP with IMR 4198 for whitetail hunting. From what I've read certain bullets need a certain velocity to expand so I'm wondering just how hot these or 325gr leverevolution/ftx bullets need to be pushed? should I aim for factory velocity with me reloads? I started tonight with MARLIN min-medium and from min-medium I got 1'' 3 shot groups. I'm sure I could get them tighter but that rifles a little odd to shoot off bags with a 7x scope. How about going faster than factory for a little flatter shooting? say factory is 1700 and book says I can go to 2k? just throwing out numbers there cause I don't have my book close.
