I just started shooting USPSA. I shoot a Glock 35 in the production division. I chose the 40SW due to the fact I am comfortable with this caliber. I have been shooting a 170 GR bullet using 4.0GR of Winchester WST. I have lowered the powder from 5.0 to 4.0 and have been able to get tighter double taps. I was now thinking about lowering to a lighter bullet. Will this decrease the recoil or add more snap to it. I use http://www.precisionbullets.com
they also make 185 so I could go heavier. Any suggestions?
