Hi, this is my first post here. I have been lurking for years. I am new to reloading 300 BO. I already have the Lee 155gr2r mold for casting for 7.62x39. I decided to try it for the 300. my problem is, that I have to seat the projectile way to deep to get it to chamber. any longer and it wont chamber in my rifle, and it wont fit in my EGW chamber checker. I don't think this bullet will work. does anyone have any good suggestions for currently manufactured molds that will work? I am wanting a mold for supersonic rounds. I don't have any plans right now to suppress. I also prefer a gas check mold if possible. I also powder coat. thanks in advance, for the help! The round on the right is the OAL that the book calls for. the round on the left is what it takes to get it to chamber. can measure it because I squished the tip
