Blanked a factory load.

[a1712]

I blanked a factory load today, 25th. shot on a new rifle. It went into the group, didn't have the chrono set up, so no idea if it was any faster. Thoughts? Brian.

Check the headspace? After cleaning the chamber.

[tommeboy]

Brand new. Brian.

The outer ring on the bolt head has a lot of chatter for a new bolt check headspace...

The blanked primer face looks really flat (over pressure?). Do the primers in the 24 other cases fired look the same?

Most likely factory round was on the short side. Cartidge moves forward from pin strike, case seals against chamber, primer backs out into firing pin causing crater or piercing, case relaxes and pressure pushes it back.

You might give Norma a call and see what they say about your lot #.
Remington 700 action?

I know one thing from pics looks like it was made in irac from Russian parts . terrible

I think they force matched your parts with a sledgehammer

 

[Coyotefurharvester]

Is it camera angle or the firing pin is striking off center?

Yes, 700 5R.
I'll do some measuring tomorrow. All other primers look perfectly fine. We've fired this lot 100+ times in other rifles. It's extremely consistent, measurements wise, and shoots really good in everything we've fired it in. Brian.

Chatter? looks like hammer marks

I personally have not shot a lot of factory ammo but have used some when client's supplied. A lot of factory ammo is loaded on the max load side as customers have a need for speed. On a long string of firing the chamber will get extremely hot and a cartridge will "cook" leading to a hotter, over pressurized round.
Just something to consider before condemning everything.

700's have a reputation for distressing primers. On the other fired cases, is there cratering on the primers?

BINGO!! BINGO!! BINGO!! Move on. Nothing to see here.
DO NOT bush the firing pin!
DO NOT replace the firing pin OR spring!
DO NOT spend a BUNCH of $$$$ trying to fix something that ISN'T broke.
Factory ammo that you can't do anything about anyway.
And don't clean the hell out of it cause if you do, you'll be starting from scratch and wondering why you can't hit SQUAT with in.
Life is WAY TOO SHORT to sweat the small stuff.

Measure firing pin protrusion.

 

[NorCalMikie]

Measure firing pin protrusion.

25 other shots with NO ISSUES!! Move on. Nothing to see here.

Is it possible you used a Rem 6-1/2 primer
or one got mixed in there?
