trying a different route here. Have a bunch of 65gr SGK's and want to try them in my 22-250 Rem 700, 24", 1x8 twist. Using varget, started @ 32.5 and increased by .3 to 33.7. Seems more powder bigger groups. 32.5 was not bad but should I go down by .3 and try lower charges? I do not have a Sierra book yet (but will) so any input would help for now. Thanks. Also do not have a chrono either.
