Yea, that's the way it is, just be careful if you prime in the dark when you close your action do it carefully to make sure the Primer does'nt fall out. It would really suck to have a shot as a nice Buck only to hear (CLICK) when you pull the trigger.
Also, I tried something new with My ACCURA, I Got some (rubber O-Rings) and put one behind the Primer, it helps reduce blow-back a-lot, but you only get to use the O-Ring one time.
Also some of the Primers are longer than others, some give you a tighter fit and less blowback.
