well, son of a gun.
for a couple of years i've had way too many 'dud primer's' with a couple of my handguns. always tried to blame the primers,and/ or myself.
well...it turns out that the Lee Ram Prime that I've been using....no idea where I got it..had the wrong spring in it,and instead of actually seating the primer fully, what I was feeling was the unit 'bottoming out' on the fully compressed coil spring.
cllipped a bit off of the spring, , went to test some rouns...NO misfires !
..a simple fix that took me 2 years to figure out,since I only load on the single stage Lee a couple of times a year.
One of those times I had loaded my cowboy match ammo on the Lee,boy did that make for lousy stage times !
Glad that one finally got figure out.
