6slr brass ?

[jkohler]

Just got 200 pieces of win brass for my 6SLR. Running them threw a 6SLR die and there starting to buckle right at the neck body junction. has any one Else had problems with some win brass lately? I have tried some old R-P brass I have laying around and they come out just fine.

I think Winchester brass is a bit thicker than Remington brass so you may want to slow down the stroke when resizing the Winchester brass. I would experiment with utilizing two passes to completely form the case. I know Robert does not indicate that is necessary but I hate losing brass so would try something different since what you are doing is not working. What lubricant are you using on the necks? You might increase the lubrication level a bit also.

If the buckling is not too severe, you can probably blow it out with a light, case forming load.

Good luck,

You might want to recheck your sizing die set up and see if that will help.
Run the die up a little and then keep setting it lower until the case is just formed to your chamber. Assuming you meant the neck-shoulder junction...

Some Winchester brass does that on reforming through the die and some does not. Remington brass never seems to do it. I think it's because Winchester brass is typically harder than Remington in the shoulder area. The right case lube seems to help. I have had good luck with Hornady One Shot spray lube. It's typically a slight deformation right behind the shoulder of the case (from reforming the shoulder) but it does not affect anything, and after the first firing you will never see it again and I have never seen it to cause a problem or a loss of accuracy on the first firing because it is rather minor. I don't worry about it as it causes no issues at all. I will try to post a picture of what I am referring to.

Originally when I made up the 6mm Super LR I had a few different batches of Winchester brass and none of them exhibited that issue when running them through the dies. My advice - carry on and don't be concerned - it's not a problem.

Here's a pic of three 6mm SLR cases from Winchester brass I just received from Powder Valley on Friday (just made them up a couple minutes ago, lubed up .243 Win brass with Hornady One Shot spray lube and ran them through a 6mm Super LR Redding Type S FL die with a .270" neck bushing). They came out pretty well. You can just see a slight crease forming right behind the shoulder. Once they are fired that permanently disappears.

Robert
that is what I'm seeing is the indent right behind the shoulder. On some of the cases it is as deep as .005 thou. I have tried about all the resizing lubes and they all do the same. The die is seat so the bolt will just close on the brass so I no the die is set right.

Best I can say is load them up and shoot them and that will be the last you see it. It really does not affect anything and it's very minor. Remington brass typically does not do it at all.

Good Luck!

Maybe, even tho they are new, annealing the thicker Winchester brass to soften up that neck/shoulder/body area a little would help. Maybe try one or two cases and check the results.

Robert thanks for the info all just load them up and see how it works. I just could think of any thing else to try on them to make it not happen. The only way it will not do it is if I leave them to long to chamber so that won't work of course.

They look just like some of my win brass(and some rem too). No rhyme or reason, but the first time they get shot, it never comes back. Funny thing is they shoot real good even with that gawd awful dent. I have also gotten dents on the shoulder from what im guessing was too much lube. They too came out just fine....

I wouldn't. I make .17 Fireball from .223 Remington and that buckle happens when I try to form too much in one pass. Multiple strokes while indexing the case seems to reduce it. I tried annealing it prior to forming and man it really went south in a hurray! Too soft I'm guessing so I scrapped that notion! Robert is correct, it hurts nothing and you won't see it again after fireforming.
