Pressure is pressure. If you drop the powder charge, but decrease the OAL and get the same velocity, you're getting the same pressure as you were before, so it doesn't really help.
Adjust the OAL so that the gun functions and the rounds fit the magazine. Adjust the powder charge to meet the velocity requirements.
Sierra's data shows a load with a 180gr JHP at 1.125" going up to 6.0gr of Universal Clays as max. Sounds like you should be fine. R,
But will that be more "kick" when I use more power?
What I mean is, If I use a STI for 5.2gr / 1.17 OAL to compare, the STI would feel softer (less power).
I know its different gun + the design, I'm just wounder if I should change to STI with better control.
I do like the Tanfoglio, but I am not a big guy to hold the "kick"
I can see some of you guys are using more power than suggested, (Eric use 5.2 on titegroup) is that because we need longer OAL ?
Or is it because of the way "Tanfoglio" design?
