I’ve have a couple of misfires lately, two out of 30 shots today. One or two testing loads recently. This is the only rifle I’ve ever had this happen. Primer strikes look normal other than it doesn’t go ‘bang’.
Pulled bullets and both had powder.
Using BR-4s. Brass has several firings. All are hand primed. Bolt has been bushed.
Bad primers? Brett mentioned maybe a weak spring?
looking for total travel measure the cocking piece from the back before and after firing with a dial indicator
You need .250″ (+/- .005″) for constant consistent ignition.
this was copy/paste from another site. assume it to be accurate.
The firing pin in my Panda bolt has two different holes that are several thousands apart. I took the thing apart some time back and me not paying attention put it back in the wrong hole which lead to a very frustrating day at the range. I have also heard it said that some primers have a harder metal than others. Yours seemed to be hit pretty hard today. Let us know what you find out. WWE
