To start with, I already have (and love) .223, .243 win, .30-30 and .300wm. i have shot a large variety of other calibers (from .22-250 to .303 brit .30-40Krag, .30-06, 7STW .300 RUM, .338wm .270 win (in savage and marlin rifles)) I live in VERY open country and long range target/varmint/hunting shots are more commonplace than jumping a deer at 50yds in timber or brush. Think WyoBraska. I have no problems with the a fore-mentioned calibers but they are not exactly what I'm looking for. I do handload for the .223 and the .243 right now and am expanding as quickly as the bosslady will let me lol. I would like a combination of speed, low recoil and bc (recoil for the kids and bosslady). I think that I probably can't get a better compromise/performance package for the local game (muleys to prairie dogs). Keeping in mind that for larger game and/or VERY long shots I'm quite content with my .300wm, I would like to know if there's anything I'm missing here for a good gap bridge from .243-.300 while still staying with my requirements. Before anyone starts beating down the smaller bore for deer, our family has routinely taken clean ethical kill shots with a .243 for decades and we hammer in shot placement in all aspects of shooting/hunting practices.
