If you had to choose one hunting bullet for .300WM what would it be and what weight? 90% of game would be whitetail deer and 90% of shots would be within 100 yards. I count at least 27 different hunting bullets between 175 gr and 220 gr available at Midway. I don't think I'd want anything lighter. I think I'd prefer slower MV for short range shots and heavier weight would offer less wind drift if I ever have the chance to hunt where that matters. I'm planning to get a new Hart Barrel installed on my rifle. A HR member suggested I load a dummy round to max magazine length (because Rugers have short mags) and ask Hart to chamber it for the dummy round. That's why I'm asking this particular question. *** Please don't waste my time telling me not to use a .300WM for this application. I know it's overkill and don't care (sorry for the attitude, someone always jumps in with unsolicited advice). The 20 whitetails I've killed with this rifle all died just fine and I do as Art Eatman always advises "Don't shoot them in the eating parts."
