Hello All,
I have read a few forums on reloading GP90 for the 1889 SM, but they all say to use a gas checked bullet, though I believe the original bullet was a paper patched tapered .316-.307 hard cast lead bullet. My question is, do I need to use a gas check? If not, would using a .308 hard cast paper patched bullet work well? Also, what brinnell hardness, or alloy would you recommend for a load going about 1600fps with a 180grain .308 hard cast bullet?
Lastly, I realize this is probably a dumb question, but I origionaly thought that GP90 was a black powder round; my question is, is GP90 just a lower pressure smokeless round, and if so, why did they do this?
Thanks!
