A crimped-primer usually means that you have to either ream out or swage out the crimp before reloading the new primer into the case. The crimp is usually put into cases for the military to prevent any backing out of the primer during firing. This means that you have an extra step to each and every case. The good news is that you only have to do it once before the initial reloading cycle. For me it's a pain and I try to get cases with non-crimped primers but will ream out the crimped primer pockets of any range brass I pick up. Good luck.
