what to do w/ primers seated to deep?
 

the title says it all...should i chamber it and pop it off and then re prime it? i have 4 out of 20. i hate to chuck them since 350 brass isnt too common

by the way these arent loaded rounds. only sized and primed

thanks in advance

You can carefully deprime, but I hate doing it. I would fire em off. A freind had one fire off while depriming with a universal deprimer, and I have been hesitate ever since.

i figured the safest way would be to fire them. i must have joe armstronged them more then i thought on a few. they are about .012!! i dont want godzilla buck to walk by and have my rifle not go boom o i think i should re prime.

When I have poorly seated or "too deep" of a seat with my .40 loads I soak them in water for about an hour, drain'm and let dry and deprime. I do wrap a towel around my press for each load just in case but have never had one go off yet (out of a couple dozen or so over the last year)

I just ease them out with my decapper, but firing them is the extra safe way :)

Is seating a primer too deep an issue with certain cartridge or pistol brass or something like that?

How critical is primer seating depth?

Thanks

If the primer will set one off without the powder and bullet in it then just load up like normal and shoot away... why waste the primers... it the firing pin will hit it, just shoot it.. you can use the de-priming pin in the die also, just don't slam it down, ease it down and you shouldn't have any problem whatsoever, if you don't feel safe, put some water in the case and deprime it that way !!

DSTATJUNK...in an ordinary hunting and plinking rifle, NO...they are so sloppy in the neck and chamber area that it doesn't matter.. in a benchrester with super tolerances, YES....but that's another story..

FYI In independent tests primers have been soaked in water for up to 4 weeks and still had a fire rate of over 90%.

Normally if you strong arm it when you seat primers it will deform them and you will see that right away. I have never been able to seat them "too deep" but I've never really tried. You can push them back out if you are careful but I would check to make sure of a couple of things before I reseated new ones.
1. are you using the correct primers ....large rifle as opposed to large pistol
2. are the pockets correct depth

I agree with skb. Just be careful and gentle when pushing them out. I've done it many times, and no bad experiences. Also, I really can't remember of ever seating a primer too deep....are you sure you are using the correct ones for the case?

yea they are the right primers. it just bothers me because im usually pretty particular but i was watching the bruins game at the same time and i think i was getting excited!!! im gonna mic all the ones i did and find the deepest one, step outside and chamber it and snap it off. if it fires i think ill load 'em up. thanks for the info.

You learned a valuable reloading lesson... NEVER handload with distractions present. One day you'll make a mistake that you won't catch and it could be your last.

What I don't get is how you could seat a primer too deep. If the primer pocket is in spec, a primer will only go so deep before it can't go any further. If the primer is deeper than spec, then either the primers are too thin (not likely), or the primer pockets are too deep. The latter is more likely the cause of this problem. This can happen either due to manufacturing defects (pocket punched too deep from out of tolerance machines), or from excessive primer pocket cleaning/reaming. I had some problems with this cleaning primer pockets with the steel brush meant for hand use but chucked up in a drill.

Perhaps he used the SmallRifle priming rod, in an RCBS hand held/autoprime, instead of the LargeRifle rod.....actually uniformly crushing/denting the tops of the primers....

Or maybe turned the rod around and used the rounded side, instead of the Flat side of the priming rod.....



This has NEVER happened to me:o:rolleye0011::wink:

Or anyone else, right?....:s2:


.

to touch on a couple of you fellas replies, the deepest was .009 to be exact. i went back and micd' em all a little more accurately. as far as cleaning my pockets all i used was a hollow ground screw driver that fits perfectly after i had tumbled just to take off the heavy and it worked slick.

also the priming rod was the large and correctly in place end to end.

i fired off the few t5hat were deeper then i would like and they poped off w/ out any problems and the firing pin seemed to be hitting about as deep as always. situation is taken care of thanks guys
