Redding .223 Seating Die Marking up bullets, Help!

[jandmtv]

hi guys, my redding seating die marks up the bullets. as you can see in the pics, it makes a round circle mark on them. I figured it might go away in time, but its not. i use lee dies for 7.62x54r and the lee dies do not mark up the bullets at all. whats the deal? i thought redding dies were supposed to be good.

thanx

You can check out my sticky'ed 223 reloading thread, I had the same problem before, and I fixed it with a dremel.

Also, from my experience, there are a couple of things you can try.

1) try to dechamfer the insider of your case a little, I also see some copper shavings

2) try to put some neck lube, or just as an experiment, put some case lube just inside the neck area, with a q-tip; this reduce seating friction


Now, from my research, those marks will NOT affect bullet performance. They look bad only. If you are running your rounds in an AR, try this - load some factory 223 into your magazine... then chamber the rounds via releasing of the bolt... and then extracting the rounds via the charging handle..... and then LOOK at the extracted rounds.... the feeding ramp or magazine lip etc is going to MARK the bullet much more serevely than your seating die.

that bullet you see in the pics was loaded before i got my case trimmer, my new trimmer chamfers the inside of the case neck, so no more copper shavings, just that damn round mark on the bullets.

ill check out the thread you mentioned.

Pull the setaing plug out of the die and hand chamfer it. It's just got a sharp edge on it.

what should i use to chamfer it? dremel and cone shaped grinding stone, then polish?

I haven't tried it yet, but I think it would work well to chamfer the inside of the seating plug using a bullet with an abrasive polishing compound on it chucked in a drill press.

All you need to do is break the edge. Don't go crazy. Just polish it a bit and it will go away.

thanx, i had a triangular carbide blade from a brake rotor resurfacing machine, it sat on the sharpe edge perfectly, i spun the blade on the plug, and took the edge off. i just loaded a case and no round mark, thanx guys!

When I run into this, I chuck the seating stem in the lathe, add lapping compound and lap it with a bullet.
A drill motor works for this too.

Are those Hornady bullets? I've noticed the Hornady jackets tend to mark more than any other bullet.

Anyway, you can send in your Redding stem and have it reworked. I know the Redding stem on my Redding Micrometer seater does leave slight marks on Berger VLDs. It's not hurting accuracy, but I figure I'll get a stem better suited for VLD bullets.

thanx for the tip Randall.

I think I've seen that brass before. Good to know it's getting used.

I only have those round marks when I do compressed loads. But I think that some easy chamfering will solve the problem.

LOL, im down to 200 or so that i havent loaded from that batch plus what once fired i had. after that last 200, all of my brass will be twice fired.
