HarperCZ Posted December 31, 2023 Share Posted December 31, 2023 My SP-01 Bullshadows drop most of the brass just a foot or two out and forward. A lighter recoil spring (from 11 to 10 lbs) made very little change. This is with 135 power factor ammo. Should I try even lower recoil spring or is this the nature of this gun? They run well otherwise. Link to comment Share on other sites More sharing options...
Rnlinebacker Posted December 31, 2023 Share Posted December 31, 2023 If you don't have any FTF/FTEs, then just send it. What powder are you using? Link to comment Share on other sites More sharing options...
HarperCZ Posted December 31, 2023 Author Share Posted December 31, 2023 N320. Yes - I am inclined to ignore the pattern for now and just run based on function. Link to comment Share on other sites More sharing options...

My A01 did this too and it functioned 100%. I also used N320 and it was at 137pf. Link to comment Share on other sites More sharing options...
