To all that know more than me...

I thought my first reloads in my 243wssm the outher day (one hole groups w/t 25 rds down the tube and first loads) but I notest that my primers are sticking out a tiny bit. I try-ed several different ways to put them in but never were they should be? The brass is winchester,and Remington 9 1/2
primers.Its not the press. I cant figger it out, plz help.

Thank you

Don't you have a small rifle and large rifle primer setup for your press? Any chance you're using the wrong one?
If you stand the primed cases upright on the bench, are they rocking on the primer or sitting flush?
 
I won't even assume I know more than you.

Couple of questions -
are you using your press to prime cases ?
How much is a little bit ?

If I had to guess....this problem can be adjusted to correct. The type of press ?
Primers should actually be about .002-.003" below the base of the case when you are looking at it.

Did you clean the primer pockets after sizing?



Have any of you guys ever actually seen enough build-up to cause primers to not seat deep enough?

I've loaded/shot brass quite a few times without cleaning out the pockets, but haven't ran into this issue.....yet.

I haven't either. He also said that his reloads were his first, so that's probably not the problem, but I don't know what the solution is either /ubbthreads/images/graemlins/confused1.gif
 
The press acctually has more compound leverage than you need,( I take it you are priming on the press) Check the priming cup that is the slideing thing the primer goes into to be pushed into the case, a small cup will not hold a large primer very well, or push it in deep enough. For the 243 WSSM you should be useing large rifle primers, they are all a strandard hight and seat just below flush when seatted properly. If yopu have been useing these in an AR I am surprised you have not gotten some slam fires. Pull down any loaded rounds you have that have high primers (DO NOT TRY TO RESEAT PRIMERS IN LOADED CASES!!!) I cannot stress that enough. Pull the bullets, dump the powder. Once that is done you can try to reseat primers NOT BEFORE! or punch the used primers out and seat new ones. All I can think of is that you just did not push these in far enough with the press ram.
 
I suspect it's not an AR as in his sig he has a browning Abolt in 243 wssm.

If the primers are even with the bottom of the case you should be fine.
If the primers stick out of the bottom of the case you need to seat them deeper, apply some more pressure.

Easy check, set your loaded ammo up on a flat surface. If they wobble around because the primer is out that's bad. If not, they are fine.
 
thank you guys and were to start?
yes it is a bolt gun
yes im using the press to prime
yes that is how i found out they were sticking out

Try seating the primer then turn the case 90 degrees and seat it again. Is the case tight in the shellholder, or is there room for it to rise up quite a bit?
Use a lot of pressure, it won't hurt anything (well, not enough to bend the press handle, but until it's tight).
I went away from priming on the press because of the lack of "feel".
 
Hello GJ2nd,
I had the exact same problem when I tried to use Remington 91/2 large rifle primers. It was the first and last time I ever tried these primers. I was loading for my .243 Winchester. I tried the primers in Winchester, Federal, and Remington brass. I also seat primers with my press, and was using all the pressure I felt I could use. My press is a Lyman T-Mag turret press. I cleaned all my primer pockets and the primers would still not seat deep enough no matter what I did. I reloaded 20 cartridges and when I would chamber them my bolt closed hard. I could see swirl marks on the primer where the bolt face turned against it. I pulled the bullets, dumped the powder, fired the primers in the rifle then reloaded the same cases using Winchester primers with absolutely no high primers. I decided there was possibly a problem with that lot of Remmington primers. They would also fail to seat properly in my .22-250 cases. I've never bought any more Remington 91/2 large rifle primers, and continue to use Winchester large rifle primers for my .243 and .22-250 reloads.
Your post made me curious, so I dug out the Remington primers and miked them. They averaged .131 in height. The Winchester LRP's I have averaged .126 in height. Just a few thousandths can make all the difference.

I've never run into this either.
 
Can we say "primer pocket uniformer"?
Get one from Sinclair and see if there is a brass problem or a problem with your seating process.
No point in guessing when you can see where to look for the problem.

What Jack said! I do it to all my new cases before reloading because I have seen cases where the primer pockets were not deep enough.

Exactly.

Just three weeks ago, I bought 300 new Remington 30-30 cases to load for my son's rifle. I could NOT seat one primer in any case deeply enough. All were protruding below the bottom of the case. So, I bought Sinclair's large rifle primer pocket uniforming reamer and opened up every primer pocket. I used a hand drill to speed up the process.
After reaming the primer pockets, primers seated perfectly.
This is NOT an issue of using more "force" to seat primers in an undersize primer pocket. It's about doing the job right; seating primers in a correctly sized pocket.
Incidentally, I only bought the Rem 30-30 cases because they were to only ones I could find. I won't be buying any more.
