270 Winchester Help

[Hillbillyz]

Just started loading for the 270 Win last night. The brass I was using was a combination of R-P from my friend (once fired) and some assorted that I have collected from the local range. The problem I have is that as I inspected the cases quite a few had split necks. If they didn't start out with a split neck after running them through a Lee full sizing die they had a split. I lubricated the neck inside with mica so I don't think lack of lubrication was the issue. I load other calibers(30-06, 7mm08, 7.5x55 ) and have seldom had split necks. Is this something that is problem for 270, do I have a bunch of bad brass?

Any thoughts would be appreciated.

No, that's not any more common with .270 Win than any other caliber.

Are the cases with the split necks in both batches, i.e., your friends R-P cases and the range pick-ups? It sounds like one of the two sets of brass were either fired more than you might think or the rifle that fired it has chamber/throat problems. It is almost impossible to create a split neck in good brass with a resizing die.

Can you post a clear picture of the cases with the split necks?

i've had cases that split on the first loading for no apparent reason... i think it is just because they were pretty old. you may have to anneal the brass.

The splits were in both batches the stuff he fired and the range picks. I pinched the necks and threw them in my scrap pile so I can't post any pics. I know the range picks I've had laying around for maybe 5 or so years, unless they were 20 years old when I got them.

I never use range pick-ups for just this reason, you don`t know their history.
I worked with a guy that I shot with a time or two. He had the habit of dumping his old brass at the line and laughting about the guys that will think they are finding a "gold mine". Most of the stuff was on its last leg if it wasn`t already splitting. He was good about polishing his cases until they shined like new and unless one looked real good they would past for it....cured me of any possible desire of grabbing "free" brass.

If mine is left at the range, it is on its last leg. I do throw it in the recycle bucket though.

If I'm loading it in my rifles, I know the history of it.

You might want to disassemble the dies and check them with a MIC and inspect for defects as they could be defective. I am basing this on new dies with no track record. Possible expander ball size not correct. RP brass tends to be on the soft side but after 3 uses I will anneal them anyway. I always do it to range pickups before first loading as well as length size them.
