i just got a lee collet neck sizer. the problem is that i'm not getting enough neck tension. even after using a factory crimp die.....i'm able to push the bullet into the cartridge with my thumb. i've heard that annealing the case necks would help. can someone teach me how to anneal? ty guys. the only other thing i can think of is to request a smaller diameter mandrel from lee precision.
I anneal every 3-4 firings, and annealing will not help. You have to follow the lee instructions, and pull out the mandel, get some emory cloth or crockus cloth, and polish down the mandrel .001 or .002". Just put it in a drill, and spin a way. Annealing is not for the beginner and can ruin cases unless you know what to look for and will not make your necks go much smaller.
