Loading 7.9 grains N350 Speer 165gr gold dot hp. CCI primers
Anyone have a pet 10mm load?
Thanx

Your load of 7.9 grains of N350 is really light. You're using a somewhat slower burning pistol powder with a lighter bullet. Also, you didn't say if you were using a standard or magnum primer, which makes a difference. I'm calculating you are running about 1032 fps in 4.0 barrel length, which is about 40 S&W speeds. If you want a reduced load, I'd recommend going to a faster burning powder. I'm showing about 9.4 to 9.5 grains as max for your powder and bullet combo. If you up your charges near max, it will greatly improve the load. I have also found that the heavier bullets typically shoot better. The 200 XTP is an absolute hammer and very accurate.

I used the N350 cause I could get most use out of it..also load 44 Special and 357 SIG. Getting good groups 44 with Sierra 240 JHC. 10in T/C
Shooting Glock 29 and Springfield XDM 5.25
Using standard large primer
Will step up to 200 XTP
Vihtavuori chart calls for 7.6/8.5
If you can recommend a different faster burning powder will defintely give it a try
Thanx

Longshot is what I’d be looking at
