Hey guys,I just registersd on this site and have a question. I am just getting into reloading and have a bunch of .300 WSM cases to reload.The cases are from factory ammunition that I have fired.I do not have a case trimmer,yet,and am wondering if they can be reloaded the first time without trimming.Is this safe,or should I get a case trimmer before attempting to reload them? All input is appreciated.
