I have some 60,75, & 87 to start with. The gun is TC 10" barrel. Maybe a 24" barrel is in my future! ? ! Powder is no problem as I load and experiment with many 22 cal wildcats and old cartridges. I'm new to the .257 cal! What range of velocity can I expect from this cartridge? I would like to start with Lil Gun, H110, & 4227. I have used Unique in many revolvers for years but never in a rifle round, what say you?
