9mm reload problem

[dsfritz]

I just got started reloading 9mm's for my wifes Walther PPS. They are not feeding at all. The range master noticed that the cases were bairly clearing my head on ejection.
We have not had any trouble at all with factory ammo.

I have loaded the following:

Rem 115gr. fmj

TiteGroup powder

3.8gr with Federal Mag primers - 1.150 COL
4.0gr. with PMC standard primers - 1.150 COL
4.5gr. with PMC standard primers - 1.160 COL

4.8gr. Titegroup is listed as the maximun load

I have been using TiteGroup in my 40cal and 45 reloads without any trouble.

Any ideas on what could be the problem?

Titegroup is an awful fast powder for the 9mm.
And 3.8 is below a starting load in Lyman (4.0 grains) & Hodgdon (4.5 grains) manuals.

Perhaps the Walther needs a more conventional, slower burning powder to provide a longer duration recoil impulse to make it cycle?

Something like WW231, Unique, HS-6, Power Pistol, etc. will give you another 100+ FPS at the same max pressure.
That would result in a stronger recoil impulse to cycle the slide.

I believe you need a slower powder. Small weapons usually have stouter recoil springs, and need full power loads to function 100%
I bet mid load of Power Pistol, will work that slide

As posted, a more fast/medium to medium speed powder, and at least a starting load, not under.

AA#5, WSF, Unique, HS-6, W-231, etc

Titegroup will work. Certainly not my choice, but many use it. If you use it, at least use a minimum of the starting load for it.
