so, i bought a 200 grain lee mold (.30 caliber) to shoot out of my 300 win mag. the question i have is seating the boolit anywhere even close to 3.340" (standard max length) will leave the gas check basically "dangling in the case" (yes, i know its crimped). but it is a concern that it could be knocked off during firing or under recoil in the case of cartridges in the magazine. am i worrying for nothing, or can this actually happen?
