I'm getting ready to start reloading some 30-30 cases, most likely with cast bullets. I have about 250 pieces and after full-length sizing them I measured them all.
There are three groups: one group of about 40 pieces measures exactly 2.030. The next group of about 150 pieces are all somewhere between 2.035 and 2.039, with most of them being 2.036-2.038. The last group of about 60 measures over 2.040, mostly being 2.040-2.042.
Do I really need to trim all of there down to 2.030? Does .005"-.010" in length matter? Will is mess up the crimp?
I guess I could do these in batches and adjust the crimp for each length, but that seems like a pain and then all of my brass will get mixed together again, unless I mark them which is another step...
BTW these will be with MBC 135 or 165 cast bullets over about 8.5 grains (that's where I'm starting anyway) of Unique, it that helps.
Advice? Thanks.
