Remington 9 1/2 Large Rifle Primer Misfires

[223ai]

I'd bet money that the shooter is using a Timney or other aftermarket trigger that reduces the firing pin spring power. Otherwise, it's an issue of no seating the primers properly.

I had misfire after misfire with Tula 7.62 primers, which are tough as nails, on a surgeon/Timney combo. Jewell/huber/Remington had no issues. Timney swapped the sear thingy for a longer one, and my problems went away.

I have had 9 misfires over 300 rounds over the last 2 months through my M1 Garand using Remington 9 1/2 lot# 2219... Shot some 400+ CCI#200 through the same gun without a single failure but switched to these in fear of a slam fire on the softer CCI#200s. I store my primers in a steel ammo can with the rubber air seal and moisture control packets so I know it's not a storage problem on my end. Idk, maybe a bad lot. I uniform my primer pockets and seat them using the RCBS bench priming tool. Going to try some Winchester large rifle primers and see if those are any better. As for shooting temp, I am in California and the temps have been between 72 and 105 during the misfires. I am sure my issues is a bad lot and not a firing pin issue either. I can see no depth difference between the once that did not fire and the once that worked. Don't have a bullet puller yet so I have not had the chance to take the rounds apart and inspect them properly though.

Sorry to hear that. Thanks for posting the lot #.

Yeah, I don't think I would try Win primers with what has been going on with the blown Win primers of late.
