All good observations. I am not new to reloading. I have mostly rifle cartridge experience. (1000's of reloads) although I have reloaded 9mm and 45acp quite a bit. I am quite thorough and careful and dont load for things I dont know much about. Loading a handgun round for a carbine gives me pause, and I knew to stop here first for great info first. Please dont argue guys. I appreciate any concerns you all have, and understand clarity of words are important, as other less careful or experienced reloaders reading this could make a mistake. Its all good. I thank all of you for chiming in. It sure is a big help.
I have a fair bit of time to do this as its cold as ass up here and I have months to cobble this together. I have a chronograph to aid my development. Getting excited. Its just a bit daunting at times when I am learning and trying everything by myself with nobody to mentor me. Things like roll crimping and taper crimping are confusing when you dont know if its done right or at all.... hence my heavy reliance to Lee crimp dies. I just read that the lee crimp die is not optimum for 357 and stopped to look for advanced help from the start.
