Primer pocket chamfering

[SixPointEight]

I've been looking around online, because I feel like I may be chamfering too much of my 223 primer pocket. Some people are saying just a small, barely visible amount is enough, however, seating primers is still pretty difficult, so much so that my primer seating tool is flattening the primers. I have to cut all the way to the ring on the case head in order to get primers to seat as smoothly as they do in pistol brass. Doing this gives me nice round primers when they're seated, but...I also feel like I'm cutting away a lot of brass.

I'm using just a standard chamfer/deburr tool by the way. I'm trying to get a decent pic.

You could try a press-mounted pocket swager or the Dillon swager.

tried those. The RCBS swage die doesn't work in my lee presses, I have used it in a friends rockchucker. It works OK but still, some primers are quite difficult to seat. This seems to be one of those instances where the cheap option works better. Never tried a super swage, but I don't have room or the excess cash.

I've used these Forester accessories in my Forester trimmer for a number of years for primer crimp reaming.

And this:http://www.forsterproducts.com/catal...?prodid=700270

You need both accessories. They work very well and are pretty quick if you have a Forester trimmer.

You can cut as much of the PP crimp as you need. Works on both large and small Primer pockets. Depth is controlled by how many turns you make.

Prices are MSRP, cheaper on line.

Do you need their trimmer to use those? I've heard good things about the horanady hand tool, and my local reloading shop sells a lyman version just like it that I'm thinking about trying. It's got two different angles on it, I guess to keep you from cutting too deep

Personally I've tried the Dillon bench mounted swager and was less than impressed. I've also tried various other tools with differing levels of complexity and found the perfect solution.

It's a simple Hornady tool with a cutting bit on the tip. Doesn't allow you to cut away any more than needed and have had great priming sessions shortly thereafter. I tend to sit in front of the TV and do a couple hundred Lake City crimped pieces at a time.

I like these:

but then I only do rifle and in small quantities at that.

Yes, you need their trimmer.

I have the Lyman tool that is similar to the Hornady listed above. I found the Lyman tool http://www.midwayusa.com/viewproduct...tnumber=643126 didn't always cut all of the crimp off and had to ream some them with a reamer.

I would try the Hornady tool since I didn't have good luck with the Lyman tool. My Lyman reamers sit unused since I found the Forester reamer.

I also have the RCBS military crimp reamer on my RCBS prep tool center. http://www.midwayusa.com/viewproduct...tnumber=565099
The reamer http://www.midwayusa.com/viewproduct...tnumber=123112 works pretty well, but your fingers get tired pretty quick because you have to hold cases with a firm grip in order to get the cut.

I've spent many years looking for a good crimp reamer and have found the Forester the best, but you have to have their trimmer to use it.

The Hornady tool posted by mattmcg is inexpensive and worth a try. Don't buy the Lyman.

I use a wilson and hornady crimp remover and both work really well. The wilson puts a nice bevel to the pocket and makes it a joy to prime.

Is the Wilson one meant as an accessory for their trimmer, or is it a stand-alone hand tool?
