Well, blown primers are usually not a headspace problem unless it is mm's to large. If your firing pin can set off the primer, it shouldn't blow the primer.

Can you place a photo of one of the blown primers?

Good morning Folks!

When does headspacing turn into a problem?

I have had three or four blown out primers in my 308 over the last year or two. Some readers might remember that I asked about it on other forums.

A month ago, when I was sure all possible causes had been checked and fixed, it happened again that the recoil felt funny, the bolt was stuck and the primer blew out.

Yesterday we determined that the headspacing was too much. The bolt closed stiffly with six patches of masking tape on the back of the case. I also have a small recess on the face of the bolt.

The basics of the rifle and load:

BRNO ZKK601 in 308
PMP cases
CCI primers
36.5gr S335
Hornady 180gr SST
2330fps
1.75mm jump

Any ideas or comments on fixing this?

I have hearf several suggestions:
- fire forming cases
- cutting the barrel and chamber
- replacing the barrel completely

Your buff really is a nice one, some are decidedly ugly brutes and yet others just seem more "good looking". A kid I taught to hunt recently shot a big buff  intruder on their farm - using a .308 and 180gr Norma Oryx bullets. His buff was one of those sparsely haired dandruff grey buff.
This one seems so beautifully unmarred.

Yo Boet ! how can you post a picture with no story 
Where was it hunted ? What rifle?
What bullet ?
What caliber?
reload or bought?
Distance ? How far did it go ? Were you alone ? Tell us more, more more !

So, the actions are then very different, Diesel/Petrol kinda different. I wondered about centering the firing pins and primers.
 At one stage i was very gingerly looking into the prospect of getting some of those rifled shotgun barrels and making a rifled S/S to shoot slugs from a shotgun at shotgun pressures.
This was gonna be my beeeg "Daaadddaaaa!" moment, but I lost steam as old age and sensibility set in.

 Fuck em !
When that false friend KK guy did his play up to me with that human horror Big T, the cause was good, get rid of a absolute cunt, the reasons only came out later when I stopped dancing to his commands. That whole GS is a little powerplay with the Superior Beings being the moderators. I must say however there are mods like Cammo that just moderate, no superior being perceptions.
             thought I would battle without GS, but I still have most of the guys on all other media.
