124gr FMJ and Winchester Autocomp

THEZACHARIAS · February 8, 2010, 03:20 PM

I checked Hodgdons reloading center and all my loading manuals, and havent been able to find a 9mm load for a 124gr FMJ bullet using Autocomp. My google and forum-searching skills also seem to have failed me here. Has anyone else encountered this?

There are loads for a 125gr FMJ, would it be safe (or not?) to use the same powder measurements, or should I order some powder I can find load data for and save the Autocomp for another day?

Im using Remington brass, CCI 500 primers, 124gr Remington round nose flat base FMJ; most likely in a S&W M&P 9.

I got this from Hodgdon

124 GR. FMJ, OAL 1.169", 4.7 grains of WSF, 1015 fps and 27,700 PSI Maximum load 5.3 grains for 1115 fps. and 32,700 PSI

Right, but his next question is: "How do I (or, Should I) extrapolate WSF data to Autocomp data?"

I looked at my stuff, and I don't see loads listed for Autocomp for 124 FMJ-RN, 9mm. Call Winchester 913-362-9455, they'll help you out.

Watch out for the 1.169" COL. I tried this length and had feed problrms with my Springfield XDM 9 mm. Make sure to remove your barrel and physically check the fit with your bullets before you start using them.

...use the 125gr load data, and it oughta be fine (but if something unexpected happens, call them and let them know).
