primer seating issues?

[Kerplow]

Im using an RCBS hand priming tool (which can be a pain in the butt sometimes) and i've noticed some of my primers aren't seating squarely. they are all below deck, but some are slightly higher on one side and have a visible mark from the seating pin. after watching the seating pin it appears as though it is favoring one side of the plastic feeder/pin guide. the does not appear to be bent. are these primers an issue? can i still run them? any suggestions for sorting out the tool, or is this normal?

It looks as if the brass you had a problem with had a crimped primer. Did you remove the crimp? Was the primer hard to seat?

[stphnman20]

Either your pressing to hard or your not completely removing the primer crimp.

crimped primer as in military brass? shouldnt be, the brass is wally world federal 100 pack.

I see a crimp

Did you remove the crimp?

And no, you can't run primers that stick out like that...boom...

Maybe

Maybe you should run the empty brass thru a decrimping die first.?

I suspect the primer pocket is somewhat tight; regardless of being Federal Brass.

Look at the ring around the primer pocket. Looks like a stake mark aka crimp to me.

i thought primer crimp was only an issue with military brass. am i mistaken? where does the "boom" factor come into play?

Happens when a primer that is not flush get's wacked by the bolt or slide face. Almost like hitting a cap. Could happen.

That's crimped primer brass fer' sure and it does not look like this brass has had the crimp ring swaged or reamed out from what I can see. This makes primers hard to get to seat straight sometimes

The RCBS hand priming system is the bomb for doing primer seating because it has such a good feel for seating point.

Buy a primer pocket swager if you have a lot of this stuff, or just ream the crimp ring off with a 45 degree deburring tool. The 45 degree lead from the reaming method always makes primer seat like butter and I prefer fixin' brass this way if they were crimped.


One more thought here, is the top of your primer seating punch damaged as in "not flat and square"? If it's OK, then is it possible that you are not operating the system gently enuff and the primers are bouncing as they get punched in place? Primer seating should be done firmly, yet softly and with a bit of finesse

Hope this helps :-)

they are all seated below the case head.

Ok

they are all seated below the case head.

Below is fine.

The only way this happens here IMO is the brass needs fixin.

Bullocks all around. i thought crimped primers had 3 little stake marks around the primer. i also thought only military brass had crimped primers.

so, I've got about 50 rounds loaded like this. they dont all look as bad as the one in the picture, and the primers are definitely all seated below the case head. whats to consensus on this, not safe to shoot? is it time to buy a bullet puller? if the rounds aren't safe to shoot i dont see myself salvaging the brass considering i wont be able to shoot out the primers.

I've got an RCBS primer pocket swager combo part#09495. im not sure how exactly to use it, and i dont have the instructions. 99% of my reloading tools were given to me.

It is definitely crimped. FWIW I've heard that some commercial Federal brass is crimped.
