Question, I am starting to load .223 and I have most of my cases trimmed to 1.750. I have one I trimmed short it is at 1.435. My question is it ok to load this short case? I have some cases that were just below 1.750 and they had been shot so I am guessing a little short is not an issue, but what is too short, and what are the effects of too short of a case.
