I loaded some .45 Colts for my '73 Uberti copy with 777 2f. I loaded by weight which worked out to 26 grains which with a thin card allowed for slight compression. The range session gave me huge groups/patterns. Groups shot with smokeless AA#5 and pyrojunk were never over 2" @50yds. I think I was good on the amount of 777. Am I missing something?
