I just opened a 50 pack of 45-70 Starline brass and measured their lengths, and was pleased to find they were much more consistent in length than the R-P that I used earlier.
The Starline measured:
2.097 11 pieces
2.099 29 pieces
2.100 10 pieces
(I measured with a caliper and grouped by rounding up the .0005 to the next thousands when separating them)
I don't have a trimmer yet, but was thinking of either just using the 29 2.099 cases for now, or perhaps blending them and the 10 2.100" cases. This would actually result in almost a .002 spread in case length -- is that too much to get reasonably consistent crimping?
Guess it boils down to "how much variance in case length is acceptable?"
Thanks,
Randy
