Hello all. new guy question
Hello all. New to the firing line and glad to be here. Not really new to reloading just a little in experienced which is why I'm here. Any who my question is along the topic of substitutions. I'm sure this question has been asked before. What are your thoughts,suggestions,do's,don'ts about case substitution. For instance alliant's freebie guide lists for the 45Colt so many grains of green dot with this primer and this bullet etc etc. But it uses all speer brass (which I was unaware speer made case brass) I have a ton of winchester brass I'll be using. So is this a no no or could I reduce the load (which I would do anyway considering all of alliant data is maximum and suggests to do so anyway) and work up to my desired performance. Please give your thoughts and opinions. Thanks folks.
