I was making up my first .223 reloads last night and I noticed my primers weren't seating all the way. I'm using a 550B and seated primers in 20 cases one at a time the other day. I then set my powder up last night and was going to do a run of 23.5gr of H335 and 10 at 24gr. On my 2nd case  I noticed it was tight going into the shell holder so I put a straight edge across the base of the case and could see the primer was ever so slightly high, I'll add they looked fine to the eye, I ran them through the primer seat again and it really took a good push to get them to where they should be, much more pressure than my 9mm reloads. Is his normal ? I have a primer pocket reamer and it's adjusted properly but it doesn't do a thing to the pocket when I use it. I'm using Rem 7 1/2's. TIA

Stop right where you are and proceed no further until this is cleared up.  Your primers are too high, and this condition is a major safety issue that must be resolved.

Describe, in great detail, how you prepare the primer pocket.  Also describe, in great detail, the exact tools used for preparing the primer pocket, and how they are adjusted before use.

This is probably something simple, so don't fret.  Just be patient, and we will have you GTG soon.

Also tell us what brass you are loading.

I am going to guess you have Mil cases and did not remove the crimp.

Don't worry, it's an easy fix, many others have stumbled here.

Was going to link to Midway with a Hornady crimp reamer, but got a "server is too busy" message.

This has happened a lot to me lately. Midway must be booming.

Don't shot them as others have said.  Just did a large batch of mil crimps using a Dillon Swagger, best way to go.

Correct, but someone just starting out with a budget, I suggest the Hornady tool.

Nothing beats a 660 for bulk loading crimp removal.

At $10 sounds good!  Might have to put it on the wishlist, since I was borrowing the Dillon.
Looks like it will be in stock on 5/12.

I have not reloaded any MIL brass but I have heard of using just a pocket knife to cut the crimp from around the primer pocket. It would be slow as hell but free if that is the problem you are seeing. SS

A case mouth deburring tool will remove the crimp quick and easy as well.  

We do need to know what brand cases you are using though.

Sorry for the delay guys, had to go into work. I'm using once fired LC brass that I got from GI Brass, I bought it processed with the crimp removed. I inspected each case and he seems to have done a good job with the crimp removed but not overdone. As I said I have a primer pocket reamer, it's properly adjusted per the instructions but when I run it through my pockets to clean them up it doesn't  do anything ie. the reamer doesn't remove any gunk or material. I ran each case through and re-seated the primers and they seem fine now, if I lay a straight edge across the case head the primer is no longer sticking out, but it takes a noticeable amout more pressure to seat them than when I do my 9mm, I've got to be very deliberate and forceful to seat them properly. I want to add here how slow and easy a newb needs to go. These primers looked fine to the naked eye, I mean I looked at them after seating to be sure they were not sticking up and these damn things looked fine, if I didn't have my shell plate adjusted pretty tight I would never have noticed the tightness when I tried to place the case back into the shellplate for powder charging. It was at this point I placed my straight edge across the bottom of the case. Man it pays not to rush things, and it's great to have a place like this where people are willing to share their knowledge. Thanks.

OK, sounds like you're on the right track.  Good work on spotting the problem right off and looking for answers instead of ignoring it.

There really shouldn't be any noticeable crud in the primer pocket itself. A thin fleck or two of carbon on the bottom of the primer pocket, where the flash hole resides is not out of line, but I use a small, cylindrical wire brush to remove that as well.

My guess is that the vendor did not quite remove all the crimp, leaving a tiny bit of constriction in the primer pocket.  Take your case neck de-burring tool, and use the more-or-less pointed end to remove a little bit of brass from a primer pocket, and then try seating a primer.  Should be a bit easier.  Do the same for the next case, but take off a tiny bit more brass.  Stop when no decrease in effort is noticed.  You will want to remove a similar amount of brass from all the cases––if I'm right.

At any rate, the primers, once fully seated, should be below flush.  Examine a few store-bought rounds and you will see what I mean.
