Okay,
Here is my dilemma; reloading 9mm Luger for wife and son to shoot in local IDPA match. It took me a while to find a starting recipe and everything is working fine except when the Magazine is empty the slide doesn't lock open. Happens on my M&P and my SIG 226R.
Here is the load:
Case: .750-.754
Prim: FED100
PWD: Titegroup 4.0g
Bullet: LEE 356-125-2R
Material: WW with 50/50 added
Actual weight: 129-130g
Crimp: med to heavy
OAL: 1.160
Chrony reports about 1090fps with slight deviation
I tried seating bullet deeper; approx .030 and huge pressure jump (to the point that the primer flowed all over.)
Change crimp and no change - primers are now flat but are not distorting out of the pocket or deforming in shape.
I have a few other powders that could use Unique and AA5.
Any suggestions? Anybody out there have a recipe for this bullet?
