gunner40sw Posted June 2, 2023 Share Posted June 2, 2023 I just picked up 4000 Montana Gold 125 gr JHP 9 MM and I want to use VV N320 powder and I was thinking about 3.5 gr which puts me about right in the middle of the load data. I just will use it for practice ammo. Anyone using this combo have any past experience with this. Link to comment Share on other sites More sharing options...
Sarge Posted June 2, 2023 Share Posted June 2, 2023 4.0-4.2 N320 at 1.15 gets around 135 PF for me. Don’t load too many without testing at lower level. Link to comment Share on other sites More sharing options...

Anyone using this combo have any past experience with this. 3.5g of N320 works great with a 147JHP; however, as @Sargeadvised, the 124/125g JHPs will like at least 4.0 - 4.2 depending on OAL.......

gunner40sw Posted June 3, 2023 Author Share Posted June 3, 2023 But VV lists the Max load for a 125 gr JHP at 3.8 rains They list the Max load for 115 grains at 4.0 Link to comment Share on other sites More sharing options...

Scroll up in the VV data to a 124g Alsa Pro FMJ @1.142" OAL and you see max for N320 at 4.5g! Always start with YOUR gun/barrel at YOUR preferred OAL, and test with a chrono while looking for pressure signs from your brass/primers. Also compare data in other publications.
