my loads and miss fires

[Evan03]

ive been loading off and on for a few years now. i may have loaded 200rds before this year. now in the last few months ive loaded and used up over 300 primers in difrent rifles.

ive had 3 miss fires while useing cci 215 primers ive had two in the 220 and one in my 25.

the first one i didnt think twice about figured i must have forgot the powder or something. even the second one i dint give much thought to.

the 3rd one is where my attention as all there. after missfired i ejected the shell and stuck in my pocket. i later pulled this same shell out to take a look. primer was dented and get this moister was bubbleing out bewteen the primer and primer pocket.

so apperantly moisture got in there. it was raining that day. rifle and ammo were in the in the elements all day. i think the primer being punched put the case under pressure and the moisture was bubbleing out like soap on bicicle innet tube.

the other missfires werent exposed to moisture before fireing.

my other thought was case lube. but i dont see that happing. after sizeing cases i clean the knecks out with a brush and cotton swaps. even if i didnt id have to have got alot of lube in the case to get enough on the primer to keep it from igniteing.

my technigue has not changed since i started loading its weird that id now start seeing missfires.

any ideas are greatly appreciated.
