from my research, Most of the commercially available 10mm loads are loaded within 50fps on 40sw loads. The only high-energy loads are hard to find, like doubletap or cor-bon. Full loads to have increased flash, recoil, and penetration, but you already new that.
Got a 10mm? Federal Hydrashoks are a lite round and have good power. I would run full power if I had a 10mm, Because, isn't that way you bought it?
My advise is: buy different ammo, have fun trying what feels good to you.
