I am loading 165 gr cast bullets for a Winchester 94. These are plinking loads and I am asking what OAL I should have. I have seated to a provided crimping groove but they will not feed and are very hard to load. The loading gate seems to hit the inserted round and it is very hard to get more than two or three in magazine. These bullets are from Missouri bullet co and are the " white tail" with the flat point. Any ideas appreciated.
