I found this bit of advise on Fulton's website.

Take a sample handloaded casing which is primed yet sans powder and bullet and chamber it. With the mag removed, let the bolt fly full force.

This test should cull any high primer or sensitive primer conditions
 
Is the suggestion that each case be checked ??

I check my cases for high primers by simply running my finger along the base of the cases . The tip of the finger is extremely sensitive & can feel even slightly high primers that look fine but are not.

As far as sensitive primers , IMO , if they do not detonate when being seated by my reloading machine then I will just use them. My experience has been that slam fires are caused by a malfunction of the gun rather than a sensitive primer.

But this is just my opinion.
 
Thats just plain weird.

If you have a primer seated below flush, I think you're okay.

I use Winchester Large Rifle, and just ensure they are consistenly below flush with the Lyman primer pocket unifier tool that WSS sells.

Thats enough to make me feel safe.
 
I use CCI large rifle primers.

I don't test every round for sensitivity. I test by the package/batch. Each hand load does get inspected for primer depth, and I do clean and uniform my primer pockets.

YMMV.
 
Never had a slam fire and I have banged 1000's of hand load through my Norc. I guess if you have a springfield you have to be concerned
 
I JUST got up from the basedment reloading some rounds for my Garand and what I do for all my 30-06 and 308 ammo (cause I don't know if it's going into one of my semi's or one of my bolts is always full-length resize and I use winchester primers (harder than most) and seat them as deep as I can, which is slightly below flush. No problems so far with my M1 and M14, and of course, the work fine in my bolt guns too.
 
Fulton has a lot of nonsense on their site. Slamfires are caused by improperly loaded ammo. Not the rifle. Seat the primer properly and you'll have no problems.
