Thank you, John! Maybe if I would have read that first along with Jerry's recommendations, I wouldn't be patching a dent in my basement ceiling today!!
(Honestly, I removed an Astra 600 end cap once and embedded the recoil spring in my kitchen ceiling!!

) I'm a p38-guy and we aren't used to living under so much pressure!!
I wonder if the mag springs are worn out and causing the problem? They are the original coil springs. Maybe I'll see if i can fit a P38 spring in one somehow and boost the mag's ejection rate. Doesn't that sound like it might compensate for a FTF problem too?
I'm thinking one of these three solutions:
1. lower the recoil pressure to allow the next cartridge time to set.
2. increase the cartridge pressure (124gr) to work/slow the recoil pressure.
3. get the cartridge in place (set) sooner.
What do you think? Dave
