reseating primer on loaded case

After loading up a bunch of .357 rounds I discovered that a few primers didn't get fully seated and they stick out just enough to prevent the cylinder from rotating.

Is it safe to re-seat the primers on the loaded bullets using an RCBS hand priming tool? Or should I pull the bullets and start all over?

Thanks.

I wouldn't do it.

You really need to question why you are having these high primer seating problems?

I won't tell anyone else what they should do. However, I will say that I have done exactly that in the past with no ill effects. When I first started using my Lee turret press and priming on the press, I had about 5 rounds of .45 Colt that did exactly the same thing. They were not seated below flush. They stuck out by a thousandth or so and bound the cylinder up. I just wasn't pushing hard enough during primer seating with the new press. I carefully put them back on the press and slowly reseated the primers again. No problem. Primers need a fairly abrupt shock to go off. It's a little bit of a risk but I use proper protective equipment and push slowly.

And yeah, make sure you figure out why they were seated high to start with and fix that.
 
There's no way in the world I'd reseat high primers on loaded cartridges.

If they weren't too high to allow the cylinder to close I MIGHT load them one at a time and shoot them. Then, one of two things will happen. The firing pin may set them on the first strike and fire them the second. Or, they will go off the first time and the recoiling case will set them flush for you.

But by all means, DON'T ever have a high-primer cartridge in a revolver if it's not the one being fired. You don't want one going off when it's not lined up with the barrel. It's a good thing you checked your primer seating before heading to the range...
 
I would never suggest to anyone to do it. And especially wear eye and ear protection and heavy clothing and have a fire extinguisher handy while you're not doing it. Because even though most accidental primer explosions probably occur when a primer is misaligned with the pocket and gets crushed unexpectedly fast, there's still a small chance that you could ignite a primer that's already mostly seated when carefully, slowly pressing it home.

Imagine the worst case scenario, weigh the risk, make your decision, and plan accordingly.

I've reseated with a hand priming tool. I wouldn't do it with a press mounted and like said above, it's NOT recommended.

How many are we talking, a few, a dozen, a few dozen. Just be aware you are playing with "fire".

Good luck

Well maybe, just maybe if I had a large piece of 1/2 boiler plate with a hole big enough to stick the tool thru.

But then maybe not.
 
Not safe, not recommended, foolish move!!!!!!!!
I've done it a few times with a Lee Auto Prime and a few times with the Hornady hand priming tool.

Make sure no one sees you doing it, that way you won't be publicly castigated for a foolish, not recommended move.
 
I wouldn't do it for obvious reasons. But in the future you might use a primer seating die such as the RCBS priming die. It's not a "by touch" tool. With mine I adjust it to the depth I need and just seat one after the other without having to worry if I got this one, or that deep enough, no re-doing. I load on single stage presses which have the primer rod on them, but I've never used that " by touch tool ". But even so, if you take the little extra time to check each primer as you remove it from the shell holder, it will save the major inconvienence of having to completely reload all of those problem rounds.
 
I have used an RCBS hand priming tool for many years.

It should be easy to tell when the primer bottoms out, or doesn't just from the feel of the tool.

And I make it a habit to run my finger over every primer as I take it out of the shell holder.
Again, it is very easy to "feel" if one is below flush like it should be, or sticking out even a little bit.

I agree with most above---don't reseat.

Just a thought: If those are "Federal" primers--DEFINITELY don't reseat them. Your odds of having a bad day are much higher with Federal primers.
 
I wish I could say I've never done it. Nothing went wrong, but it really could have, and I feel pretty dumb for ever having thought it was worth the risk. Pull em and go from there.

If you have to ask, then you shouldn't be reloading in the first place.
 
I have a question for all of you whom are suggesting that this is a bad idea under any conditions; have you ever had a primer set off while seating it in an empty case? I never have, and I have never heard of it happening. I would do it. Eye protection isn't a bad idea, but I think the blanket 'OHMYGOODNESS DON'T DO IT' statement is a bit overkill.
