Orville Loomer chamber ...
... 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.

Re: Orville Loomer chamber ...
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. ???? bobwrfd wrote:... what are the resulting .45-2.1 chamber dimensions and how do they compare with the standard Shiloh chamber ream?

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.

Re: Orville Loomer chamber
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.

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

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