I would like a recommended powder charge using V V N133 with a 40 gr bullet for my 20 TAC.

I cannot find that info in my searches.I did find for 32 & 35 gr bullets. I am loading 24.0 gr with 35 gr Berger bullets and getting very good groups @100 yds.

Thanks,

Todd Kindler's early testing:

VV N133, Hornady 33 gr V-MAX, CCI 450
start load 24.3 for 3782 fps
end load 27.4 for 4235 fps
according to him accuracy was very good but the
velocity was lower than he got using H4198.

Just and fyi, he prefers RL-10x for Hornady 33 and 40 gr bullets, he uses SPL for coating and Win SR primers. With 25.9 gr of 10X he gets 4,000 fps using Hornady's 40 gr.

There's also a ton of data on loaddata.com

Cheers
