yeah,you need to try diffrent powders/amounts in your gun. It will tell you which one it likes the best. My Pro Hunter likes 3 pyro pellets with a 250SW,and a Fed 209A primer. It also likes 120grs. FF T7 with the same bullet/primer,but I hate the crud ring! :? Clean up is a moot point with the T/C guns,as they are simple,and quick to clean up,so corossion isn't a concern. I've shot my gun on opening day,spit patched the bore,reloaded again,and left that load in for two weeks (during dry weather) and never had the first speck of rust anywhere in the gun. Now if it's raining,that a diffrent story. ALL FIRED powders ( even smokless powders) are HYDROSCOPIC (attract moisture like a sponge,some are worse,than others). If I fire the gun,and reload, then later that night after the hunting is over that day, I will tear it down,and clean it real well. Then reload for the next days hunt. No rust,no problems! Ron
