Is anyone loading 300-grain bullets in the 45 Colt case over 2400 powder? I just got two lbs of it for free and I am wondering if I can make any decent loads for my 45 with it. I know I can use it for 357 loads but it seems like it might work for 45 Colt too. I'll check my manuals when I get home but ... thought someone might have first-hand experience in this area. Thanks.
