i do i do.
with 165gr Rainier's i load 6.5gr's of Unique with an OAL of 1.120", primers? take your pick i have used cci and wsp. That is pretty close to a factory loading.
180gr Lead flat nose, 3.5gr of Bullseye 1.120" OAL, wsp/ cci. I have used these alot and loaded up over 2000rds of it. I even used it in a training course. Accurate, reliable, and mild recoil very light recoil for a .40 for sure.
also you can go with the 4.0 gr of bullseye with the above and get a mild recoil load as well, they have been a little more accurate than the 3.5gr for me anyway.
155gr Lead Round nose 4.3gr od bullseye 1.130"OAL wsp/cci primers.
very light recoil, Just enough to work the action, they have been 100% reliable.
By the way i am using a SA Xd service model. It eats anything i feed it.
