Two sorta' general questions...
1). If loading rifle rounds at the VERY low end (aka: START LOAD) of a range from, say from 101 to 108gr, how important is the OAL really? If, for example, the bullet is loaded 0.070" deeper, say 3.485 vs. 3.555" (and with the rim to the cannelure) because the load data length puts that bullet style into the lands? A "fatter" round-nosed bullet vs. a pointy FMJ.
So, 0.070" Shorter vs. Plus 7gr powder?
2). How important is case MAX length, as long as the rounds chamber? There is current load data, for example, for the 7x57 Mauser that has a MAX case length of 2.235" and a "trim to" length of 2.225". Other, earlier data and even diagrams show a MAX case length of 2.240" and even as much as 2.243".
If they fit the chamber, does an extra 0.005" case length REALLY make any difference?
Thanks in advance for your kind consideration and experience!
Cheers!
