Read this thread with interest. I, too, have had problems with One Shot case lube. I thought it was probably my Redding dies causing the problem. It turns out, it was probably a combination of the two. Being the frugal sort, I refused to throw away a perfectly good aerosol can of case lube, tho.
Happy to report it is all gone, and I am going to start using the Frankford Arsenal spray lube, or make my own.
I have the ISO HEET, but liquid Lanolin seems hard to come by locally, so I guess I'll add a tube (2oz.) of Lee resize lube to a bottle (12 oz.) of the Heet. That is about 2X the recommended dose of lube, but it should work.
Whilst on the subject, I remembered I stuck one case in my .270 Hornady dies some time in the '80s, and didn't have another problem till I switched calibers and die makers in the mid-90's...257 Roberts and Redding. They cost more, so they should be better, right?
Well, I took the sizing die apart, and looked inside with a strong light.
Woah!
it appeared very rough... circumferential scratches the first 1/2 inch, then diagonal ones from there. Not at all like I remember my other dies, and I don't recall ever doing anything that would produce those scratches!.
So, as recommended, I did the 400 grit in a split dowel trick, and followed it with 1200 grit, then polished some more with the 1200 and 3-In-1 il. Much improved.; scratches gone!
NOW to see how that works! Maybe time to switch back to RCBS?
Thanks, guys!
