Looking for some guidance here. Worked up a great load using Hornady Amax 208 grain Using IMR 7828SC shooting half MOA at 300 yards. Shot a deer at 340 yards it was eating lead and copper with this bullet. Decided to switch over to the Hornady ELDX 200 or 212 grain but having trouble getting them to pattern. Tried H 4831 reloader 22 and H 1000. I'll have failed to yield similar results with either of the 200 grain or the 212 grain ELDX.is anyone shooting with 300wm want tips on cartridge length and bullets
