I have a scoped Ruger SRH in .480 ruger. I'd like to maybe reach 75 to 100 yds for prairie dog shooting. Don't want heavy recoiling loads. Looking in Speer #14 12gr-16grs of unique is the powder charge weight for their 275 Jacketed HP . I figure I'd seat to the crimping grove with a heavy crimp. Is there something I'm missing ? 32grs of H110 with same bullet is a heavy kicking load that I'd like to avoid.
