I came across a fella in the south east that makes some dandy cast bullets. I bought a bunch of 165 grain .310 diameter gas checked bullets from him to shoot in my 30-30s. I know they shoot real well at 2000 ftps in the 30-30. I'm wondering what to expect when loading them in my .308. I have never driven cast bullets very fast in anything.
In the 308 @ 2500 fps would make one heck of a deer load. Would that be pushing them to hard? Will they as ftps increase eventually lead in spite of the gas check?
