jwilkinson6 Posted February 28, 2018 Share Posted February 28, 2018 I want to develop a 40 minor for 3 gun. I'm using 165gr black bullets over titegroup in an STI which usually has a 14# recoil spring in it. Any help would be appreciated.

Pirate Posted February 28, 2018 Share Posted February 28, 2018 3.5 of TG and switch to a 12# Spring. That Spring is good for major pf also. Link to comment Share on other sites More sharing options...

Postal Bob Posted February 28, 2018 Share Posted February 28, 2018 (edited) 3 gr titegroup, 180 gr Ibejiheads, 1.185"oal, 10 lb recoil spring, 130 PF. It's like cheating. Edited February 28, 2018 by Postal Bob Link to comment Share on other sites More sharing options...

Sent from my iPhone using Tapatalk I haven't put it across the chrono yet. It just feels sweet compared to shooting a 180 blue bullet and 4.3 grains of TG for 170pf.
