OK, so here’s the deal. Just got into PC’ing and did a boat load of 405gr hollow base for my 45-70. As advertised, the diameter of the bullet grew from .459 to .461ish. No big deal right? Just resize, load and shoot. A quick visit to Midway, order a Lee push through sizer, wait a few days and BINGO! Range time.
Problem is, Lee doesn’t make a sizer is .459. They DO make one in .457.... Say what?? I’ve always been under the impression, when shooting lead, to oversize the boolit by .001. Makes sense and has always worked for me in all my other guns. If this is the general theory, than what the heck do you size with a .457?? I can’t find a single weapon that is chambered in .456! Are some of the early Trapdoors undersized or am I missing something besides the $43 if cost me to special order a .459 die from Lee. I guess I’ll find out how these pretty new boolits shoot in 60 days when my new die arrives.
