PSA case blow outs

[A78729]

I'm I the only one getting case blow outs? It's already my second one. I think it has some thing to do with the amount of casing that sticks out of the chamber.

Hello: Check to see if there is enough crimp on your reloads. As another note some factory loaded ammo gets setback of the bullet as well. Are all your shots sounding about the same? If not you maybe getting bullet setback causing your over pressure problems. Thanks, Eric

Are you running a 5.5 oz. buffer?

I had one on my PSA with Blazer factory 115 ammo.  Only one in about 5,000 rounds on this SBR.

Post a picture so we can see what you mean.  "Case blowout" could mean different things.

Most likely your brass. 

I had a few before I knew about the stepped and ringed stuff.

Yup.  That's stepped brass.  It's an issue with PCC as well as open guns.  The only solution is to weed out the headstamps.  IMT, FM, AMMOLAND.

 

Search stepped brass on this forum and you will find out more.

What bullet, weight, powder brand and load, and OAL were you using?

[desmondj]

Definitely stepped brass. I had to clear one last night.
