Help - Wall Thickness at the Muzzle ?

[Drew Hause]

That's all I have Bill, but here's what the Brits say

UK Working Standards recomended minimum wall thickness measured 18" from the breech from Double Gun Classics p. 56, Vol. 1, No. 4 Jan-Feb, 2006:
2 1/2" 12g- .028
2 3/4" 12g- .032
Re-proof recomended minimum- .024

Thanks, Drew. I kind of like the .032 figure, on the assumpion that some day any 2 1/2" gun will be fired with 2 3/4" shells. As some posters imply, the muzzle is no big deal except to hunters who may bang against a tree or fence post occasionally.
