I have a pound of 3 n 38 and I want to find a load for 9mm with 147 gr campro plated bullets. The only loads I can find are 5.9 t0 6.5 gr. 6.0 gr gets the case 3/4 full and the load would be severely compressed. Has anyone have any knowledge with 9mm and 3N38?

They have an app with reloading data, maybe some info there?

Thanks kawi but that is where I got it, among other places, stevespages . I will start out a t 3.5 or so and work from there.

I don't know about 3n38, but I load with N340 for 9mm with good results. For 124g and 115g loads all of them are compressed, and I have never had bulged cases/primers or non burnt powder down the barrel, that is through a jr carbine, as well as a H&k p30l v3 and a p2000, a S&W M&P9 and a sig p226. For the 124g loads I use 4.7g of powder and for the 115g loads I use 5.1g of powder, I cant remember seating depth for the 124g but for the 115g I seat to 1.119" OAL. Both are snappy and fairly accurate.

Go to Hodgdon's site they have a link to VV.

147 gr Hornady they have down for 6.3 start and 6.9 max. But omg, 1137 fps on a 147gr bullet is insane, so I wouldn't go near that load.

VV N310 is 3.4 grains on 147. This isn't published anywhere because you can double load the cartridge and get it to fit in.. so it's a hazard.

I've always been told open shooters use 3n38 so I never went near the stuff.

I would probably start at 3.0 or 3.1 grains on a gun I didn't like.

to give you an idea of 3N38 for 9mm, but mine is 9major,
8.6gr 3n38 / primer- small rifle
oal- 1.170 for the 124gr projectile, 1.150" for 121gr.
a little bit of a compress load, but still safe on my gun,
velocity- 1340fps for the 124gr, 1365fps for 121gr

3N38 is a very slow burning powder which is what makes it ideal for shooting in an open gun. I would highly suggest that you do not go below their suggested minimum as you could have a case detonation. There is a minimum for powders for a reason.

I agree, Very slow powder. If you go too low of a charge it's going to be very dirty also. Slow powders like this are better suited to high velocity loads.
Get a faster powder if you want low velocity loads

This is where I found my load data for my 9mm 124gr. Using v-3n38

6.4 for about 1100fps
