You really need to swage primer pockets for the Ginex primers to seat properly. Even then some may get a little high (not seated fully).
I tried Ginex, never again, even if they are free. They do go off 100%, the issue is with seating fully.
I love Blazer, Speer and CCI brass in 9mm in general for reloading. I don't reload same case 10+ times thou. I'm speaking 1x fired brass.
Federal is high up in my book too.
I do get 1x fired brass all the time so I don't pickup what I shot at matches.
IMHO, if one likes 147s and TG, try 124s and Clays
One needs access to chrono to gauge their own gun/load PF. I run a load with PF129 for USPSA/IPSC/IDPA.
PF mostly depends on barrel length and how 'tight' the barrel is - quite 'individual' values.
I used +10% springs in my 10rd mags, only thing is - tough to load last couple of rounds but I use UpLula ever since I cut my 'loading' thumb at work just before a match
400 and then 1000 grit is what i use. +10% springs is all I use, 10rds mags take them and work 100%. Arredondo mag brush makes it fast and easy to dis-assemble and clean mags during matches.
Yes you can use +10% springs in 10rds mags without cutting them.
I'd recommend you smoothing out and polishing mag lips where they come in contact with top round thou.
Using TS walnut grip panels for years, they are most def working for me.
I saw and 'felt' some very nice alum panels too but just cannot justify another $80 as I feel they are not worth that to me.
