223: careful with PMC cases, they tend to bulge more at the case head in my experience with them, I avoid them for that reason, primers look ok to me...
Cool. Thanks for the reassurance. Everything felt ok firing them. I didn't test anything.for accuracy yet. Just wanted to make sure I was doing things ok and not gonna blow up in my face.
Next thing you need to do is buy a chronograph and see what velocity your getting.
Some bullets perform better at higher or lower speeds, so knowing how fast your going will get you to that place quicker.
Also, your going to need to start sorting your brass now too. I/E- Once fired, twice fired...., especially with soft brass.
Keep on Keeping on.
