308 to 260

[lightflight]

I have a bunch of 308 win brass. It would prefer to be 260 rem brass. With out all the technical jargon...How do I proceed?

Do I just run it through my 260 sizer?

Thank you for any guidance provided.

Lube and resize w/ your 260 FL die and check for length of brass to make sure it is not too long. New Brass works much better than fired brass.

I just learned and did this with 308 - 7mm.08. I HIGHLY recommend Imperial Sizing Die wax. The stuff works like a charm. I found out that the resized brass though was juts a hair under minimum trim length. But it will grow once I shoot it. I also asked about going form 308- 260 and I was advised that you should resize to 7/08 and then 260. I however as of yet had the opportunity to try it.

I have done 30/06 brass to 6.5/06 in a single pass w/ no problems and
+1 for the Imperial Die Wax and a little goes a long way

I take .308 mil-surp brass down to .243 in one pass, so i think you would be fine going to .260. If i had a 7mm-08 or .260 die i would use that as a step in between but if i go slowly and use lube they size down without cracking in the neck area generally.

Great feedback. I use imperial for WSM and other Cal.s and like you all have said... it is good stuff.

I guess I thought there would be more to this.

I've been using the Imperial Sizing Wax for a while now, and definitely have to give it 2 thumbs up, as well. Great stuff!

But don't use too much of it, or it will cake up your dies. However, it is recommended that you will need to clean your sizing dies regularly, anyway. So, if you practice this, then this part of my post will be redundant. LOL

Kiwi shoe wax also works well, and i am told that lip balm in the little tins also works!

Can I de-prime with the 260 die during resizing or should I de-prime 308 first then resize? First time trying this. Thanks

Nice thread resurrection. I have done 30-06 to 6.5-06 with one pass and it doesn't matter. I have a universal decapper now. I recommend imperial as well and next time I will try a tapered sizing button.

Good luck and shoot straight y'all

I use to do this with lapua palma brass I would run it in a 7-08 and then the 260 then I would have to neck turn I just buy 260 srp brass these days to save all the trouble
