I loaded with VV N320 way back when VV first came to the US. They recommended using Red Dot load data, and I loaded thousands of 9mm 124gr with the Red Dot max load in the Lyman Manual. (I want to say it was 4.0grs, but double check me.) Ran great and the gun was cleaner after shooting than it was before! VV makes great stuff.
I load the 124 gr Match Winner with VV N320 for USPSA competition.
4.0 grains with an OAL of 1.123 gets me 1050 fps out of a CZ Shadow 2 and a Sig 320X5, 130 power factor.
I’ve chronoed it over a Pact chrono as well as 2 different Lab Radar chronos, functions perfectly in both guns
Palmetto dagger s 9mm 4.5” barrel w/ vortex venom 3 moa dot. Rmr 124 fmj rn ( seconds) w/ 4.2 gr of vv n320 @ 1.131 produces 1071 fps ave and one ragged hole at 10 yds. Super clean and bullseye accurate! My other load of win 231 4.5 gr@ 1.130 with same bullet was great too but n320 is so clean and less recoil, excellent bullets!
My Steel Challenge load “powder puffs” is 3.5gr. VVN320 with RMR 124gr RN @ 1.115 OAL. 850fps. I use a softer recoil spring (can’t remember lbs) in my shadow 2 – 100% reliable, same for JP5.
If I’m not feeling lazy, I’ll drop to 3.3 – 3.4 gr with the same other data for my JP5, it eats them all day. Have to use a really light spring in S2 to keep cycling.
