Evening everyone.
I’ve got a strange problem with a new rifle and I’m hoping you wise Gentlemen may be able to shed some light on it.
From new, my rifle has had a reduced power trigger spring and an extractor upgrade kit, both from Black Rifle in the UK. It’s had 200 rounds of CCI Mini-mag through it prior to this shoot without a problem.
Last weekend, after about thirty rounds, it was firing normally then ‘click’. First thought was misfire so I followed the safe path and waited 30 seconds before removing the mag and carefully unloading the round from the chamber so that it fell on to the bench.
Careful and close inspection of the case showed no marks of any description from the firing pin and only a slight mark from the extractor claw. A quick look in the breech/bolt area showed nothing obvious so, thinking it might be just ‘one of those things’, I loaded the round back into the mag whereupon it fired as it should.
Halfway through the next mag (10 round) the same thing happened. Another round with no indentation. Then after 7 rounds from the next mag, it happened again.
I called it a day at that point and when I got home stripped the rifle expecting to find either a broken firing pin or a hidden piece of crud preventing a clean hit on the rim.
Nothing. Nada. Zilch. Everything’s clean and seems to be in perfect working order. I checked the firing pin carefully, compared it’s overall length with a spare and it’s only 0.1mm (0.003937”) shorter than the spare so I can’t see that being the cause of the problem.
Has anybody experienced this before or have any suggestions on possible causes? Anything would be greatly appreciated.
Thanks
Iain
