... what are the resulting .45-2.1 chamber dimensions and how do they compare with the standard Shiloh chamber ream?

I've ordered the OL chamber ream for the forth coming Sporter #1 as ppb's are all I'll be shooting, just want to compare the OL ream against some others. TIA.

I can't answer your question.

Well a std Shiloh chamber gives a casing a .483-.482" dia OD after firing. OL chamber, the fired casing will have an OD right at .472".473" that leaves the casing with a ..450-.451" ID after firing. No resizing needed, it's away a lot of the Sharps cartridges were chambered in originals. The 50-70 and 45-70 (2.1") were chambered larger to accommodate gov't greasers ammo though. You can't chamber a round loaded with a greasers in a OL chamber. ???? bobw

good scoop, bobw - thanx. those are about the before and after firing spex i was expecting. perfect.

i *NEVER* want to load greasers for bpcr, ever again ... and was clearly aware of the OL chamber not allowing a greaser to enter. good.

Bobw-THX for the info
What is different from the std Shiloh chamber and the OL in the leade/throat?
G.

RFD if you ordered one of my chambers for the 45 2.1 (45-70) the chamber dimension ar the end will be .478 with a 7 degree lead. You will still be able to load a .457-458 lubed bullet, the cases will have to be neck sized to hold a bore size pp bullet or astandard RCBS sizing die may size it enough to hold the bullet also without expanding. This chamber is a copy of an original Borchart chamber.

THX Orville. What is the leade of the std .45 chamber in a Shiloh?

thank you, orville - nothing better than getting straight scoop from the creator!

again, no lubed bullets gonna run down the bore of my forthcoming shiloh, it'll be ppb's all the way.

2.5 degrees.

Chris.

The lead on a standard Shiloh chamber is 45 degrees with a 2.5 throat.

Thank you.

Sorry rfd for the mis information. I was thinking of my 45 2 7/8 chamber and Orville was right on the money. bobw
