The question I have is one of my favorite loads out of my .338 Lapua is 96 gr. H1000 with a 250gr SGK. I would like to experiment with other 250gr. heads.
Hodgdon is telling me max. charge for a 250gr. head is 98 grs. of H1000 and Berger is saying a max. charge of H1000 for their 250gr. head is 90gr., as an example.
I am wondering why such a difference in charge for the same weight head? I certainly don't want to lose velocity or performance.
Different tolerances? Can different manufacturers change pressure that much with same weight heads?
Thanks.
