Wheeljack Posted May 13, 2018 Share Posted May 13, 2018 When I used coated bullets, I found the coating to be uneven. If I bought a .356 diameter bullet, I would run them thru a .356 Lee sizing die. Check out your coated bullets at different points along the diameter. Link to comment Share on other sites More sharing options...

Wheeljack Posted May 14, 2018 Share Posted May 14, 2018 I haven't tried them all, so I can't say. If I do use coated bullets I just automatically run them thru a resizing die. Link to comment Share on other sites More sharing options...
IDescribe Posted May 18, 2018 Share Posted May 18, 2018 ACME is the most consistent I've dealt with, and I measure with a micrometer. Keep in mind what happens to the bullet when it gets engraved and passes down the barrel. Of you're running at the bottom end of acceptable sizing, a sizing die might help, but if you are running at the upper end, I don't imagine that it makes much difference. The nice even coating going I to the barrel is going to be altered as soon as it enters the rifling anyway. Link to comment Share on other sites More sharing options...

I placed an order with Gallant for two diameters last week but all I've heard is 'crickets'. No indication of shipping date, no response to an email, and no return call after leaving a message. They have been bumped down the list a few notches. Thanks for bringing up the idea of measuring for consistency. I'll run a few EM's through my dial calipers.

IDescribe Posted May 18, 2018 Share Posted May 18, 2018 Gallant is in the process of switching from a part-time 2-man operation to a full time job for the owner, and they just got hammered with a bunch of orders. It will settle out soon. You're dealing with their growing pains. ACME are typically .356 to .3565, so not necessarily up to the size you want. And their .38 bullets sized .358 have lube grooves, which I typically avoid for coated bullets. In your position, I'd stick with Eggleston for the time being. And give Gallant some time to get up to speed. Link to comment Share on other sites More sharing options...

Eli did call me today and indicated their growing pains so I was glad to hear that they are still up and running and my order of samples is underway and will be here soon. So for now I'll see what the Gallant's are all about and how they run down the barrel and continue with Eggelston's. Link to comment Share on other sites More sharing options...
Ludde Posted May 24, 2018 Share Posted May 24, 2018 (edited) Quick question to you all. Please give your expert opinion. Every now and then, perhaps 1 or 2 per 100 rounds a bullet keyholes on the target. I use VV N320, mixed brass Los copper plated 123gr FP ~130pf. The barrell has been thoroughly cleaned and that helped a bit. It helped also somewhat when I changed from 145gr to 123gr. Initially I could use 145gr without problems also. Do you think I have too much crimp? Edited May 24, 2018 by Ludde Link to comment Share on other sites More sharing options...

Do you think I have too much crimp? I''m certainly not an old expert but from what I've learned from this thread it appears that you might have too much crimp on that bullet. What does your case measure on a crimped bullet? Link to comment Share on other sites More sharing options...
Wheeljack Posted May 25, 2018 Share Posted May 25, 2018 (edited) Crimp looks good to me. The shells mouth often has a lip on the inside that causes the line. But, like Bench said, measure. Edited May 25, 2018 by Wheeljack Link to comment Share on other sites More sharing options...

When you try acme, code "54730" will save 10% I also didn't see this potential "issue " listed..... Your seeing "rotate, stick, rotate, stick" which indicates an out of round or lumpy condition. that could be the bullet, but more likely the case wasn't belled enough. Or the bullet was placed on the case crooked. That can cause the coating to be shaved .it can build up inside the case and make it lumpy. You should also buy a case gauge for your caliber. I recently bought a 100 hole checker to do a whole box. And failed... miserably. had to improve my methods an add a bulge buster step. Just a couple thoughts.

Do you think I have too much crimp? 2 Yes. Your bullet appears to be deformed where it crimps. Check the diameter of the bullet from the crimp to the base. It should remain at the factory size (normally .356 for plated). Also, are you using the Lee FCD? Because the crimp seems to have a rather long taper to it. 9MM is a tapered case and normally set back is not an issue. Link to comment Share on other sites More sharing options...

Do you think I have too much crimp? YES that is way too much crimp. You should not see a ring, and that bullet looks outright pinched. Set taper crimp for. 378 and be done with it. And if using Lee FCD, stop and get a regular taper crimp die. Link to comment Share on other sites More sharing options...
MemphisMechanic Posted May 25, 2018 Share Posted May 25, 2018 @Ludde switch to a coated or FMJ bullet for 500 rounds or so. I bet it goes away. Plated bullets are rather notorious for tumbling when better bullets (either of the other two options) will not. Link to comment Share on other sites More sharing options...

As soon as the case walls are visibly straight again, and your ammo case gauges 100% stop there. Less is more.

Ludde Posted May 26, 2018 Share Posted May 26, 2018 Now I've done some measurements & adjustments to the press. What's your guys view on the findings and result? Mixed brass same 123gr LOS copper plated FP bullet re-adjusted the case mouth flare a bit and the roll crimp. It is hard to be real exact when measuring the case mouth after crimping getting the jaws of the calipers as far out on the case edge as possible. I also made sure to measure same case several times and use several samples to get a couple of average measurements. I have not case gauged them yet... https://www.los.si/en/copper-plated-bullets/ Link to comment Share on other sites More sharing options...
