I shot a load in .30-06 that yeilded roughly a 1 inch group at 50 yards and I want to stretch it out to 100-150 yards. I loaded a LEE 160g cast round nose bullet w/GC over 16 grains of Unique, CCI 200 primer and tumbled in ALOX, I talked with a guy tonight that told me he shot 150-170g bullets over 18g of Unique. My question is, isn't 18g of Unique a little much pistol powder for the .30-06? He told me he was hitting clay pigeons and grapefruits at 200 yards with this 18g load but he used Lyman bullets and Remington primers. This is a Winchester model 70 if it makes a difference.
