Failure to fire help (Solved)

[DocRDS]

Load testing today.
Virgin Hornady Brass.
Win Mag Primers
10% did not go bang. Of those about half fired on a second strike. All handloads. Factory ammo appears to be fine although obviously this session hand a single factory round fired.

I did have these primed for about 2 months before loading (life ugh) I don't know if that was the problem or something else. Pics to follow.

All had a good dent in them. These 3 refused to fire (powder loads varied, from 73 to 80)

I notice the one is slightly discolored. Almost certain they have had powder (going to pull now)

I read about primers being high and i noticed my priming tool sdid not bottom out on them after I pulled bullets and i could squezze them in more. Perhaps less time in the bear pit and more time strengthing hand

Had this happen once due to contamination during the loading process.

My guess is primers not fully seated, allowing the primer to slip forward on firing pin impact and absorbing the energy instead of detonating.

Actually I did have a high primer once. Good call. Bought a 21st Century Priming tool. Problem solved.

Yeah i went and reseated them after pulling--rechambered one (no powder, no bullet) and it fired (scared the fuck my wife and both cats were like 'Wat dis nao').

Scrub reloader is a scrub, now I know that its just not 'resistance', it really has to go all the way down my priming tool.

Remington 700? I've had issues with my R700 lighting magnum primers.

I would also check primer depth as magnum primers have a thicker cup and take more pressure to seat.

Its a bergara premier. I know everyone says you can feel the primer 'bottoming out', but I can't and I suspect that I just didn't squeeze hard enough (RCBS hand priming tool). My other handloads seem fine, but this is the only magnum rifle and yeah, I'm still kinda new to it. ID-10-T error.

Good news is, I can fix it and not have to throw out primers--yeah it cost me three rounds, but I fertalized the flowers with powder and learned a lesson.

Glad you figured it out.

Mine was definitely firing pin related because it set about 80% of them off. I ran the rest through my AR with 100% ignition.
