Have a Colt DE 2010 model. Reload for 9 and 40. Now for 10mm. Bought some Precision Bullets RNF 185 gr Hard Swage Coated. Been using Unique, with the powder shortage here, I may as well keep using. Been looking for a load. Have a couple books but nothing right on. Mostly just put holes in paper. Bought a Chrony, now going to start working the load. Thought I might start at 6.2 gr and work my way up. Any one have any experience with this type bullet and powder. I'll also be loading for my 40 Kahr P40. Thanks for any help.
