Thread: Brass damage ?? Help

Hi folks
Just been up the range this arvo and I've used half a box of Hornady 168grain (308) . So the issue I have had is the brass is getting damaged by the bolt and 2 of the primers have turned a bluey dusty colour and the bolt is very sticky when unloading. Otherwise it's fine with the Winchester 150grain. The rifle is browning X bolt (308) . Here's a pic aswell

What you have described and shown in your photo is excessive pressure warning signs.

You'd do well to heed these warnings before it ends in tears

The signs are the evidence of gas leakage around the primer, the extractor marks on the head stamp and the sticky bolt lift.

What you haven't mentioned is this factory ammo or reloads.

In the meantime I'd just stick with the 150gr ammo.

Cheers
Pete

Id be taking it back to whom ever I bought if from in that case as they are not safe to continue shooting in your Rifle.

On a warmer day these 168gr rounds may fail in a catastrophic way causing severe injury to the shooter and/ or anyone nearby.

Can you see any evidence of head spacing issues on the empty cases?

Cheers
Pete

Awesome Pete exactly what I was thinking and yeah a shot of the front part of the spent cartridge might be important to see and signs of head spacing issues as Pete has also suggested - but yeah classic pressure signs!

Was it Superformance? They had problems with some 30-06.

I am not sure about the lingo of reloading so not sure what headspacing is but here's some pictures

Some are OK but the leaking primers also look a bit flat. Time to go back to where you purchased them!

Some good stamps in there

The raised circles where the brass has extruded into to the ejector pocket

Yeah sorry mate. This bit

Hornady putting some extra super into supper performance - I guess!

Faulty load - I'd say they hadn't changed the fill from the previous on the line. A bit of a worry and explains a recent SP 308 box I bought can you show the lot number sticker in a photo and I'll grab mine too to compare ( if I can find it)
