High Primers

New to reloading and was running 45acp and noticed 1 out of 20 would leave the primer high. At first I thought I was probably short stroking on occasion but I disassembled 1 cartridge and put it back in the #2 (without any new primers)to see if I could seat it properly but it was still high. I tried it multiple times and I'm sure I pushed the handle all he way back.  Is it common to have occasional high primers?

Thanks Brent

you probably have a ringer that is when the decaping happens the old primer   dose not come out all the way it only knocked out the center it happens when brass gets moister and rust the primmer in that has happened to me with used brass decap all your brass first to make sure your good so you do not waist primers hope this helps

Thanks for the quick response. I appreciate the help.

is it possible that those cases are small primer cases? i always sort for that before i clean the brass

Suddenly had high primers on my 650XL, checked all recommended possible causes (assured my shellplate was tight). Found that problem was the primer seating plug had backed out slightly. Wrench fixed that, no more problems! Note that this is problem is not listed elsewhere, but add it.
