Got a couple of suggestions that might help
Depending on your intended use, I personally prefer to use a 40 grain
Sierra Blitz King bullet. Powders, AA2015, Reloaders 7, H322, IMR 4198
Vith N120 are all good. Remington 7/12 primers does a good job for me
for hunting bullets. By very carefully starting with a lighter load and
very slowly working up and watching fro obvious high pressure signs,
you can really get some outstanding velocity & accurace out of these
powders and a Sierra 40 grain Blitz King. I particularly like this bullet
becasue of the flat base and perhaps a little longer bearing surface
that this bullet offers. The impact is devasting. Good luck.
