They were good articles and most appreciated.
I have access to a Mansion wall thickness gauge and a Skeet's Bore gauge. The Skeet's won't handle 10's for bore diamater but the Mansion will measure wall thickness. Can measure the barrel wall thickness, choke length, and chamber length with it.
Only 10 hulls I have are fired 2 7/8 RST's and new primed unfired 3 1/2 inch Remington's. Saw the photos of 3 1/2 inch shells in the 2 7/8 inch chamber. I would expect the unfired uncrimped empty 3 1/2's would do the same thing, stick out past the extractors while the fired 2 7/8 would drop all the way in.
