As expected my 308 puts a slight crease in the cases about half way down. Some dents are deaper than others. I Know a resizing die will make everything good again, but was wondering how safe is it. What really happens if you blow a case on a semi-auto? And would it be ok to resize creased/dented cases. When I reload my 45ACP pistol cases I have had cases split with no ill effects on the firearm or myself. I know the cases on a .308 have much higher pressures. I wasn't going to load heavy loads, but maybe improve the accuracy on my new 308 carbine.
