Shaving coated lead 9mm bullets

No, you can see the shavings on the case rim after the bullet seating step. Crimp is unrelated.

Post some photos of them, I can't see anything.

Will try to get a pic tomorrow unless Poop beats me to it.

Here we go. I tried 3 times and this was the only bullet sufficiently jacked up to show up in a terrible iPhone picture. Weird how it works when you don't want it to.

Sort of hard to see but I drew a box around it. A lighter arc where you can tell the coating is scraped, with the lead peeking through in two spots. Other bullets I've pulled are variations on this theme.

I should note that this is only after seating, no crimp.

I bet it is the bullet not straight and tilting enough in the case mouth to kiss that side because of the lube groove.

Kind of like the bullet on the left side of this photo, just not as bad.

Take the seat out of the die and take a photo of how the bullet aligns with it. Maybe a modification is in order for it to work correctly with the rather SWC shaped bullets your using.

I'm already using the flat end of the seating plug. Maybe I could use epoxy or something to mold it to the bullet?

I've also read claims that the Mr Bullet Feeder poweder funnel helps the bullet sit straighter in the case.

Depends, that is why I asked for a photo of the relationship between the two.

Note the two "flat" seating stems on the left of the photo I posted, they work for different flat tipped bullets. If your seater allows the bullet tip to go side to side then epoxy might help if you can get it to cure centered or machine it after it is cured, at that point I would just machine the seater correctly into what's there.

Just ordered some of the blue bullet 147 RNs sans lube groove. Hopefully this'll do it. I'm using bayou 147 FPs with lube groove right now.

Spiff · Feb 23, 2016

Good news. Got a sample pack of 147 RN Blues without the lube groove and a quick test shows 6/6 going plunk with no shavings. Same die settings with lube grooved Bayous resulted in 3/3 with shavings and a much mushier gauge. Thanks!

JMorris · Feb 23, 2016

Wow, what is the OAL variation on those blue bullet rounds? Looks like a lot.

Spiff · Feb 23, 2016

Heh, I was excited about trying the bullets out and left the die where it was for the FPs. Ignore that little guy in the middle. Those are all dummies.

poopgiggle · Feb 23, 2016

well when I've shot through the few boxes of the lube-groove flat points I have, I'll have to get some of the non-grooved variety.

What press are you loading on? I just ordered a Lyman M die to put in station 3 on my 650. I wasn't having shaving problems as long as I have the bell just right, I ordered this just in the hope that I don't have to be so anal about setting the bullet perfect every time and it speeds up my loading. I'll post up some results in a few days.

I'm on a 550. You can buy the DAA bulletfeeder powder funnel which does the same thing as an M die but doesn't take up an extra station. I've got one on the way, even though it looks like it's not going to be necessary.

Dillon problems. Get a Hornady LNL and be done with it.

:49:

^^^^^^

lol @ Jared.

Dennis I had a LNL, I tried to make it work. I've made $3 million CNC mills and lathes work for years. I couldn't make that LNL work.

dennishoddy · Feb 25, 2016

Mine has worked flawlessly for many years now. Never had any issues.

All of my rejects over two years sit on the side of the bench. Might be a dozen. Most are because of the primer slide got hung up and didn't put a primer in. Didn't notice the primer tube was empty.
I have a witness rod in there now.

JMorris · Feb 25, 2016

I had a few issues with the LNL's I had but it didn't take much to solve them. Would pick one over a Loadmaster 8 days a week and even they can be made to run.

FWIW the Dillon low primer alarm and rod work on the LNL.

I had heard that the DAA powder funnel would solve this problem but I was hoping there was a solution that didn't require me to spend more money.
