Alpha 6PPC Brass

Has anyone actually shot this brass, and if so, how much did the oal increase? In my .262 neck 6ppc with .050 freebore my lengths increase an average of .022. From an average of 1.503 to an average of 1.525 + a .001 or more at times
This is my story and I'm sticking to it;
the increase in length came from turning the necks down to .0082 for my .262 necked chamber, not from the initial firing.
I never thought to check oal after turning, will do from now on
Hmmm. I've never seen that...from just neck turning. I can't wrap my head around that one. Either way, that's quite a bit of stretch from whatever caused it.
 
Thank You! Keith.

Any reviews on it yet? I am buying the fancy drop port Savage that was listed here. I looked, decent price; now I need to talk to the builder and get his opinion.

Just a quick sketch Al. lol

I am Italian roast over here myself pal.

This brass looks good. I turned one piece. I will not have any trouble fire forming. Hopefully the stuff is tough and the primer pockets hold up to the abuse. Time will tell.

Years ago, turning necks for a .222 with a well used K&M turner, I noticed that my cases had lengthened several thousandths (.007 comes to mind, but it has been decades) after turning, with no other operation having been performed. My conclusion was that the cutter was dull, even though it seemed to be cutting satisfactorily. A new cutter solved the problem, reducing the lengthening to a fraction of what it had been before. I doubt that very many shooters regularly check case length before and after turning.

You're right that I don't typically measure before and after turning, at least not for this specific reason. Different turners..many use the end of the case as a stop on the mandrel, so I would trim a tad to establish a uniform length first, then lightly deburr. I use a bit tighter mandrel fit than most people. Not sure if that's a factor here at all or not. But, once done and ready to load is when it gets measured again to make sure it's not too long and verify how much clearance I have from the end of the case mouth etc. I don't recall any significant change, for whatever reason. Again, I don't recall ever specifically looking for it though.
I'm mot a fan of the job of neck turning and have gone no-turn on most things now and also, I use a lathe more often than a standard neck turner too. I do find it interesting that it's growing for some people though and will pay more attention in the future.
 
A dull-ish cutter and a snugg-ish mandrel cutting a fairly thin neck can definitely result in 'pulling' the case neck forward when it's being turned. In my early days of neck turning, I saw it first hand. -Al
+1^^^ Same here, on several brands of brass. A mandrel with not enough or inadequate amount of lube gives the same outcome. JME. WD
