I have the Lyman 452490 mold for my 45 colt. The problem is if I seat the bullet so that I crimp on the crimp groove then my bullet is to long to work in my carbine, it works fine in my revolver. I looked on the Lyman site and it lists this mold under 45 colt but in their reloading manual it lists it under 454 casual. My question it can I use these bullets in my 45 colt and just seat them deeper, just past the crimp groove? Or should I not use these at all. I hate to have to buy another mold but if I do who in Canada sells Lyman molds. Oh I am using Trail boss powder at 5.5 grains if this make any difference.
