I have been a reloader a long time, but mainly rifle and .357/.38. I have lately purchased some bullets and powders to try loading some 10mm and .40 caliber. I have several types of spent shells and have been inspecting them(all once fired) and was looking at some of the off brand types. I have Federal, Winchester as well as other ones. I don't feel comfortable reloading the silver ones, so I wont mess with them. Are there some casings brands I should just pass on? I am using a set of RCBS Carbide crimping dies in my Rockchucker press. I am going to start on the low side and find a comfortable good shooting load. My guns that I am using are all Glocks Model 22.23 and model 20.Been doing some reading lately and getting ideas as to others loads and taking notes.
