usmc1974 Posted February 19, 2006 Share Posted February 19, 2006 I am shooting 147 fmj with 5.7 grs Alliant power pistol at 1.180 OAL getting 1130 fps, in my para p18/caspian slide with a briley 5.25 comped ramped barrel I was wondering what is the best recoil spring weigh to use?

Scout454 Posted February 19, 2006 Share Posted February 19, 2006 I'd say 10 to 12 pounds. Wahtever it takes to consistantly strip rounds out of the magazine. Link to comment Share on other sites More sharing options...
usmc1974 Posted February 19, 2006 Author Share Posted February 19, 2006 Thanks, I think I have a 10 but the rounds come off the mag like butter. I was more worryed about the slide coming back hard maybe hurting the frame. I also use a shock buff is this a very high perssure load it is listed as 34000 out of a 4 inch gun Link to comment Share on other sites More sharing options...
