I'm pretty new to reloading. I'm reloading for a 10mm G29. I'm using 155gr berry's round nose bullets and cci 300 primers. The only thing is the powder I have is hodgdon clays. 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.
