Thank you all for the suggestions!
I don't have a chronograph, but have considered picking one up. These loads are for my wife's revolver. We've got some great loads for 158 coated and plated semi wadcutters, and we're trying something new.
I shoot a Glock 21, and had a great time shooting some poly coated 230 grain round noses today. I have a long way to go before I'm ready to compete, but enjoy plinking and hand loading.
I checked out Alliant's website-no data for flat point with the powders I have, but data for Gold Dot HPs for Bullseye and Unique. Between that, some other info on other forums, Winchester's data for a lead flat point, and numbers from loaddata.com, I think I have some to start with.
Thanks again!
