Delayed primer ignition

[XLR]

Whet out shooting my cheytac today and experienced a strange phenomenon. About 1 in 10 shots had a delayed ignition. Trigger would click...1-1.5 seconds...then ignition would commence. It is not a light primer strike as the dent in the primer is substantial. None of the primers are pierced. Has anyone experienced this that can shed some light on this? I have used this box of primers with other cartridges with no problems. Primers are CCI 0015 LR Magnum primers. Thanks

Be sure you store your primers in an ammo can with a few desipacks thrown in. Primers can draw moisture. Store them well and they will last.

I encountered the same with a 408CT. Was trying some very slow powder I use in 50 BMG loads. I changed powder, but used same lot of primers 'Federal Mag' and no more problems. About 1 in 8 was my ratio of hang fires.

What kind of powder and how much you using? Depending on powder it may take a compressed load or real close to keep the powder up against the primer.

Re: Delayed primer ignition

Were you tumbling your brass before hand? I've seen it happen where a piece of media gets stuck in the flash hole and causes the situation you described.

Powder was US869. No media in brass.

Re: Delayed primer ignition

RAT, what is going on is i bet you started the loads not near enough to case cap and the powder came off the primer and caused the hang fire. Give me a call and i can help you out.

I had hang fires using US 869 in both the 375/408 and 338/408. It only seemed to be a problem with light loads. If your problem persists drop back to 50 BMG with near capacity loads, (approach carefully) In my experience the BMG is more consistant; however, the 869 will give you about 100 fps more than the BMG.

Re: Delayed primer ignition

I had some delayed ignitions with my 260 remington and assumed it was due to below minimum powder charges.

Re: Delayed primer ignition

I had the same problem with a 300 WBY mag. with 4350. SLOW BURNING powder lets you hear that click and you think. "What the Hell?:" Then all a sudden BOOM!!!
