I purchased an Optima Elite for hunting this year, 50 cal ML, .270 and .223 . When I went to the range the ML worked great and grouped at about 2" at 100 yards. When I switched to the Centerfire barrels, I cleaned the face of powder residue and the first 3 shots were fine, then click....... nothing I waited 5 min, and checked the cartridge, primer was hit, but obviously not hard enough, this happened several more times, with occasional booms in between. Same thing with the .223 barrel, this was all with Winchester ammo. Any suggestions? the breech was closed firmly each time.
Thanks
