I haven't really found any data for how much to use in a 10mm. I'm wanting a safe load I can use just for plinking, that won't drop the shells on my hand. I heard to just take the maximum load for a .40 S&W and use that as the starting load (which I did find some data for the .40S&W)
Also wonder if anyone has a good recipe for some lighter loads for plinking and stuff.
You are on the right track loading Berry's in the 40S&W range. As mentioned above, Berry's has a speed limit and it is way below a 155gr bullet's potential in 10mm.
I favor 180gr jacketed bullets for my 10mm loads and buy Blue Dot and AA#9 in bulk for this application.
For lighter bullets like 155gr and 165gr, when you are ready for true 10mm velocities there are a lot of really good powder options.
I would recommend the 10mm reloading forum in the Gun Club section of GT, full of great advice, frequented by guys that love and really know the caliber.
