Were you fire forming 7-08 brass into 7-08ai when you were getting the misfires?

Hi Norm , no brand new 308 Palma brass.

Regards Graham.


So you were fire forming! Your headspace is too long for that unformed brass, I would say.
Hard seat your projectile or use a softer primer as suggested.

Same sort of thing happened to me with my 6 dasher- I went to a softer primer for fireforming. It saved wasting CCI450's with every 3rd or 4th not going off to all of them going off. Not sure how you were fireforming, but a 30 thou jam, 3-4 thou neck tension and a soft primer was fundamental to get them going off every time.


Brad , that sounds exactly what was happening to me ! U maybe onto something ! Righto I'll try again with fire formed brass . But what gets me is that I kept cycling the bolt and pulling the trigger until the primer caved in !

But the above is worth trying out with fired brass!


Graham,
I don't think you understand how a primer is ignited,they need a hard sharp hit on a supported case,multiple hits on a misfired primer rarely fires them.
