	Unearthed my wife's HW and she reminded me that it lay quiet for years because it split cases. Today we shot about 30 cases and some 6 were split-- 6:00 position vertically as case stands along throat and neck of case about 1/2 to 1/2 inch. Several smiths worked on it some time ago and the last one John King remarked some sort of problem with the chamber that he would fix gratis, but cant recall what the problem was. After about a year it started the splitting and by then Mr King was retired. Any ideas what the problem he discovered was--or is?? thanks

	Sounds like you chamber is too big to me. How do the un-split cases compare to unfired cases? Are they larger in diameter at the front?

	I trust that the fired cases that didn't split will not be full length resized and the necks only partially sized if at all.

	Definitely needs to do a chamber cast and measure carefully to verify its chambering beltfed/arnie

	split vs unsplit seem identical; Max accuracy requires full length resize; no it is the Winchester 32-40 chambering Today splits dropped to 1/2 yesterdays %. There was some sort of issue regarding the chambering error and i simply cant recall what it was. Perhaps John Taylor can weigh in I wiil seek private email thanks

Perhaps John Taylor can weigh in I wiil seek private email thanks You mentioned John King in your opening post. If your chamber was done by John Taylor you might get information from bpjack about his 32-40 JT chamber. As I remember it was not standard. Jack may still have the barrel.

	Maybe the brass simply needs to be annealed.

	It is a modern Al Story 32/40 barrel. So I know the chambering is 32-40. it was profiled and installed and chambered --believe by Al Story and a new HW breech block made by his bud who I think was named Lewis as he wrote at least one article about Al's barrels; it was sent to another smith who did nothing for over a year and finally for finish work and fixing the single set trigger to John King who discovered an error in the chambering that so upset him he called me and fixed it gratis. John Taylor has yet to see this puppy. It is about "splicing"? part of the chamber
