VV-N350 in 10mm

[tayninh69]

I've loaded PP up to the Hornady max load but only gives around 1150 fps velocity just as their data said. Tried max book loads of Blue Dot and never came close to book velocities. The article I referenced got more velocity with accuracy out of N-350 that's why I asked my original question and wanted to try the powder. Not looking for nuclear loads, just a solid 1250 or so like an original 10mm load in 180 gr.

n350 will give you that. I have found VV load data to be spot on as far as velocity, an example is 9mm Hornady 147 XTP with 3N-38 powder gave me 1197 average out of a Sig P226 and the book says 1207

What is the max for PP that you used?
