Safe to reload pressure sign brass

[TnKen]

I have been working on loads for my new 358 win and have some brass that show pressure singes on head. I’ve never had any pressure issues before because I don’t try to push the limits when I load, but this rifle showed signs 3 grains below max. I was just wondering if I should toss this brass or keep using it.

Bolt gun? If so, how was the bolt handle lift and extraction? Any stiffness or extra effort needed? A bit hard to tell how flat that primer actually from looking straight at it vs from the side but looks pretty flat. Also looks like there’s a mark on the brass for sure. If pressure 3 grains below max, time to switch powders and try again.

The only time I’ve switched brass was when 416 RM Norma brass proved too soft and had extraction issues with multiple powders. Suggest trying one or two different powders first before abandoning brass. I’ve had good luck with H4350 in larger calibers, it’s the lowest pressure power for the 35’s on up.

Yes it was a bolt action, and was sticky on the lift. I have reduced my loads and have one that is giving above book velocity, but with less powder and no more pressure signs

Back powder off and continue to chronograph each round.

Some manufactures brass is a bit thicker and this happens.

I suspect when you chronograph appropriate velocities the pressure signs will go away.

Just my 2 cents.

That primer is definitely flat all the way to the edge, but not cupped around the firing pin.

It's hard to see if there is a bulge ring just ahead of the extractor groove, but if not I'd say the bass is still good.

Is the brass all the same manufacturer? As @ftrovato posted, some brass is thicker than others, and will produce different pressures.

I'd definitely try a different powder and primer combination, starting loads then work up from there.

Unfortunately the answer will be; it depends. If it will still hold a primer, I keep on using it. If it won’t, then it’s trash. I have a lot of brass that looks like this and keeps on trucking with lower (normal pressure) loads

If the primer pockets are still tight i would use it again & reduce the propellant charge a little.
