Autocomp & 135 grain bullets

bartmessina · August 15, 2010, 01:04 PM

Have looked at everything I can find on the Autocomp powder but can"t find anything on a 135 grain FMJ 9mm bullet. I have had these bullets for years & need to load them. Please can anyone help with the powder.

Thanks

Welcome to the forum.

I am unaware of any published information on that powder and that bullet weight. Based on the data for other bullet weights, and assuming the 135 gr. FMJ is 0.625" long and seated to 1.135" COL, it looks like the ballpark starting load will be 4.3 grains and the maximum about 4.8 grains. This is all mathematical conjecture on my part and cannot be vouchsafed by any practical experience with it. If you have a chronograph and those two produce roughly 940 and 1035 fps, respectively from a 4" barrel, then you'll know they were close.

I'd suggest going to the Hodgdon website and using the data for the 147 gr bullets. I assume these are the Zero FMJ bullets. While a decent bullet, the weight is not an ideal one for the 9mm. But since you have them and want to shoot them, I assume as pllinkers, use the 147 gr data and be a happy shooter.

I use 135 grain cast bullets in 9mm (I don't know why that bullet weight isn't more popular) but I use a max load of Bullseye instead of Autocomp.
