Question:
If I start reloading my 7.62x54r and 7.62x39 ammo, does a 7.62 nato (.308) bullet fit in those cases and would it present any problems when fired? I ask because there are some special hunting bullets you can not get in the Soviet cartridges, but you can buy the bullets seperate from the cartridges. They would be heavy for the SKS and light for the M91/30, but no particular problems were apparent when I considered it. I do have some reloadable Winchester brass.
from what I have been told and see done.
a lot of it depends on the rifle it self.
does the Russian bullets measure .308, or .310?
also what powder do you use?
find a reloading manual with the data for what you want to reload, get two or more manuals, compare the data between each one, then work up a load that your rifle likes.
start on the low side and work up.
Gas rifles need specific types of powder, not to fast, not to slow.
check your brass after firing them, they will tell you a lot about what is going on.
if not sure, find someone in your area that reloads and ask then for help.
good luck
