Looking for reloading data for a Zero 115gr JHP in a SIG MPX

This is a reloading question but it is specific for PCC and it was suggested by the guys in the reloading section that I aske it here.

 

This bullet was recommended to me.  I have done some research on the Hodgdon website and found a load for 115gr Speer Red dot JHP which I presume is close to the Zero's 115gr JHP.  Looks like they recommend a COAL of 1.125" and titegroup range between 4.5gr (low) to 4.8gr (max) for an MV between 1,135 and 1,258fps.

 

FWIW, I cannot do a plunk/twist test for this gun because of the generous chamber because the barrel is meant for a sub gun.

 

Anyone use something like this and I wonder how well that works?

Your OAL looks fine.

 I won’t run Titegroup through my MPXs. I run 4.2 grains of VV320, behind 115 jhps.

A slightly slower burning powder would be idea (assuming you have a Gen2 MPX)

 

Also why can't you do a punk test? Remove the barrel, drop a round in, turn it upside-down.

Hello: Try your 115's JHP's. 1.140" OAL, 4.0 grains Tite Group OR 4.0 grains Clean Shot, Winchester small pistol primers. That is a pretty good load for a MPX. I shot those loads in three different MPX's I had. Quick cycling and gets back on target fast. You want to be in the 138-145PF range which I found was the sweet spot for me. Thanks, Eric
