Ever make a dumb mistake? I thought that the Redding S Bushing FL Sizer die had a standard bushing installed. Uh, no.

So I tried to seat some bullets in my primed, trimmed, cleaned, primer pocket uniformed, flash hole deburred cases, and I discover that the case mouth is enormous. Then it hit me what went wrong. So I lubed them up again with Hornady One Shot and resized them in my other die, which correctly sized the case mouths. Now the lengths are all off, stretched out to almost 1.758 or so. Then I started retrimming them, but somehow I messed up my Hornady trimmer and some started coming out short. I think I have it reset correctly for 1.750, but I was so frustrated that I just quit for the night.

So, when I'm feeling like tackling this project again, a few questions:

1) Did I ruin the seated primers by possibly getting some of the Hornady One Shot lube on them (not worried about the outside, but if some spray got inside the case mouths)

2) My trimmer is reset for 1.750, but a few got messed up and are trimmed back to 1.740 or so. Can I still load these cases, or should I just deprime them and reuse the primers (if they're still good, see question 1)

3) Since my poor cases just stretched to 1.760 from 1.750 (something wrong with my old Hornady sizer die? Seems like a lot of stretch, and I lubed the necks with the One Shot) even the ones retrimmed correctly to 1.750, should I just fire them one and get rid of them?

I am really annoyed at wasting all the time preparing 100 cases and realizing they are probably all ruined. Arghh...
 
Seems unlikely. The spray would have to be enough to get to the bottom and would then have to get through the flash hole. And it would have to contain a chemical that would render the primer inert. Since WD40 and oil won't do it, I doubt One Shot will.

You could always douse a primer with One Shot, place it on a cement floor, cover it with a piece of paper, and hit it with a hammer to test it. Ear and eye protection, of course, although they're only like a loud cap gun.
 
Shrinkmd,

It's not likely that the Hornady One Stuck ruined your primers, but you really should use a better lube with bottlenecked brass. It's fine for straight walled handgun brass (especially if using carbide dies), but it fails as a serious lube for rifle brass. Your brass that you shortened a bit too much is fine - just shoot them. Don't beat yourself up too much over this, chaulk it up to experience.:)

Thanks for the advice! I did a little more reading around the net after my post and found more of the same.

I will dig them all out of the trash and load them up.

AND I will measure my brass and back order those Redding bushings...
 
From the back of the One Shot can:

"One Shot Case Lube won't contaminate powder or primers."

I've never had a problem with it, and it certainly worksd well for me as a "serious" case lube.

Yes go ahead and use those shorter cases.
 
Glad you got it figured out and I agree Hornady One-Shot lube isn't that great for bottleneck cases. I use the RCBS lube with a roll pad and it works great I just lube every other case and its plenty.
 
That is the best way to test them. Better than hitting them with a hammer, even with eye and ear protection. :)
 
Given how well the directions and product work for the actual intended use, I wouldn't doubt that its possible it corrupted your primers.

However, I wouldn't count on that foul ichor doing ANYTHING correctly, or permanently.

As someone suggested- I would try ten of them without charges and see your results.

As to your brass.... Are you using two separate FL dies ? Are you using two different shell holders ? Something is obviously out of adjustment. I'm sure we can pin it down.
 
"I thought that the Redding S Bushing FL Sizer die had a standard bushing installed. Uh, no."

No. If you want a 'standard' neck size, get a standard sizer. The bushings only have application for those who wish to do it non-standard and Redding can't even guess what diameter someone may wish to size to.
 
One Shot shouldn't have any negative effect on the primers. I agree with the one poster, I won't use One Shot on bottle neck cartridges. The best bottle neck lube I've ever used is called STOS,it's sold by Ponsness Warren (yeah, the shotgun people) If you call to order a bottle ask the order taker what STOS stands for, it's actually pretty funny and I can't post it here without getting banned.
 
I feel your pain Shrink. Being new to the program, I've had several "quit for the nights". Better to just hit the sack and try again later sometimes. I usually figure it out on that 2nd day, and it's usually right after I just sent out a gaggle of frantic PMs asking everyone for help. Then I'm like "crap I really wish I wouldnt have bugged everyone with my dopey question.



Not saying your question was dopey

I shoot only pistol, so I didn't want to suggest shooting an empty case with just the primer because I didn't know how good an idea that was for rifle. When I hit a primer with a hammer all I got was a little black on the cement, but no flash. That was after I tried to crush it in a vise. Part of a test after some people were saying you shouldn't deprime a live primer. A vice just isn't a fast or sharp enough blow.
 
Next question

I went through the brass, and I only needed to trim one or two. The rest were all about 1.757 or 1.758. The few I messed up with the trimmer the other day were in the 1.740s, but one 1.378. I will load these cases for standard plinking load with some Hornady 55 fmjbt.

Then I found my old 223 brass, which is 5x fired. I was using the RCBS X die, so they've never been trimmed after the first time. I need to check the lengths and inspect with the paper clip on the inside.

I was really frustrated because the brass I ruined was meant to be used in some testing with some Varmageddon bullets and some SMKs.

Would I be ok trying out some accuracy loads with this 5x brass, or should I make up a new batch of once fired and do all the extra prep? The old 5x brass was not primer pocket reformed or flash hole deburred. Just trimmed and then chamfer/deburred. At least the cases are clean from stainless wet tumbling.

I was thinking of primer pocket reforming the 5x brass. I'm using a plain 20" barrel and 4x scope, nothing fancy.

Thanks
