Thanks....it dawned on me a few minutes ago that I'd left out the powder...yes, it's H380.
I appreciate the response......
I realize the bullets are different designs by different manufacturers.....but that still strikes me as a pretty large differential....not explained by bearing surfaces or...
I bought some 100gr Partitions to load for my .257 Roberts....I plan on hog hunting in a couple of weeks in Texas. The max load in the Nosler #6 manual is 40.5gr, and on Hodgdon's online data website, the starting load is 40.5gr and the max load is 44.0gr. Why the disparity?
Thanks in...
