Advantage of mouse farts? in SASS Wire Posted Sunday at 05:13 PM I did a little test. 130s vs 105s in my pistols. My pard loaded and timed me. I did not know which I was shooting. On average, about 8/10s of a second faster on a 10 shot sweep. May will day 8/10s isn’t enough to worry about, but 8 seconds in a 10 stage match Is huge! I load 3.2 Bullseye in both. I tried reducing the powder, but found I missed “feedback” from the guns. I also tried the 105s In my rifle. While they fed fine, found that I did not like the feel of them. now I shoot 105s in pistols, 130s in rifle. Both with 3.2 bullseye. Only adjustment I have to make is about a 1/2 turn of Bullet seating die.
