I did call Sig and they suggested trying different ammo.(duh)
I went out and fired 100 rds of Magtec 230.gr .45 ACP without a single feed problem.
The powder id been using smells funky and under a glass seems to have 'rustlike' patches........
OK........i purchased a 4lb can of 700X......and loaded up 24 rds with 3.9 gr
(3.6 is starting load and 4.9 is Max)
going to the range I fired my 24 rds and had 8 FTF's.......the recoil was even worse than my other loads.
One reader mentioned my new main spring. I think this is the problem.
cant find my old 1
I loaded 24 rds last night with 4.5gr of 700 X and will try again tonight
