elk, Sierra Bullets told me the top powder for the .25/06 was I4831.. I shoot 100 grain Sierra's in mine.. Very accurate, I 4831 shoots fastest, then Re 22, and finally I4350.. All are very accurate.. I think I4350 has been consistently accurate for me in the diff. 25/06's I have used.. Nice rifle.. Great coyote gun..
