Pressure Sign on Factory Hornady Super Performance

[Edinburgh Rifles]

Unless the bolt is stiff I wouldnt worry
Hornady brass is soft as shite
There is no free lunch when it comes to velocity
Faster bullets require more pressure which requires faster or more powder which can leave signs in some rifles
They wouldnt be on sale if they didnt pass proof
Most factory ammo is waaaay under CIP limits
Mof it shoots and poses no lift or extraction issues just use it and bin the brass

This ^, stop fretting,
I had some stuff years ago, not Hornady, two rounds had hard lift & the primers fell out in two bits .... Rifle was undamaged, & no bolt face cutting, that was the time to get rid of the ammo.

Re-read the OP, the powder flow is combined with a stiff bolt lift.

Measure the case at the base of the web , adjacent to the head . Then compare suspected over pressure cases to those that appear to be within pressure .

Not being at the front of the Math class in (prison camp).... read school, what is the mathematical / % expression for a one in nine slightly smoothed primer event,?

The primers aren’t the issue, it’s the brass flow on 6 of the cases combined with a stiff bolt lift.

Not looking for a brass flow computation though.

What do you mean?

I think you need to read that primal rights article you posted….

Pretty sure he is MENTIONING primers, don't you?

And to what part of it are you directing to?

No he isn’t, he mentions marks on the head stamp and a stiff bolt, no mention of primers at all!

Have you been on the pop Finny?

 

[25 Sharps]

And to what part of it are you directing to?

By the look of things all of it, but particularly the section on brass glow on over pressure rounds that can be very subtle or very obvious as they are here. Similar to the ones in the article where he is consciously going over pressure with his creedmoor, just before the primer pocket lets go.

Primers are mentioned in further posts and OP comments on primers.
You got a sticky keypad?

The primers aren’t the issue though finny, what’s been established.

You’re the one who started harping on about primers and you clearly don’t have much of a clue. You either can’t see or are totally ignoring the fact the brass has flowed back into the extractor recess on 2 thirds of the cases.

As I say, read the article you linked and expand your knowledge…..

What people are saying about soft brass may well be true, sako brass in ceeedmoor is similar.

This is still an issue, you may not get a catastrophic failure of the rifle but the brass is close to letting go of the primer. If it happens is no good for the rifle, can damage the bolt face and a face full of gases from the primer pocket is no fun at all. So I’d not be using this ammunition at all, or pull it, drop a grain or 2 and then use.

My knowledge needs little expansion thank you, I don't play the harp either, Impressed marks are on most fired ammunition, just some are more visible, If every ammunition lot that bore marks went back we would have nothing to shoot.

Be interested to hear how the primers seated when reloading the brass.

you really have no clue!!

My guess is the op isn’t a reloader

Indeed, so we may never really know.
Or he could post me a few….

No I'm not. Live in Ireland so cant do it legally.
