40-90BN and paper patch

[Michael Johnson]

Another issue that has cropped up is that the brass from Rocky Mountain Cartridge has a slightly larger rim diameter 0.615 as compared to the Starline 45-2.6 which is 0.610. The Starline of course uses a RCBS #14 shell holder with the RMC using a #5 (like my 348). In fact the CH4D dies for 40-90BN specify the use of a #5. Makes me wonder about the size of the extractor used by Shiloh. I already have an excellent long range Sharps in my 45-2.6. I am intrigued by the muzzle velocity that the 40-90BN is capable of. I am thinking that with a 14 twist barrel, 420 grain PP bullets, heavy gun, and wiping between shots that this could make for an interesting long range cartridge.It sounds like the standard chamber is the way to go and that with a proper bullet the standard lead will work just fine. Both my 40-65 Hiwall which has a Shiloh chamber with a 0.600 length straight neck and my 50-90 Roller which also has a tight chamber (Dave Manson) with no throat to speak of shoot PP reasonably well I just have not shot PP in them as much as I have with the 2.6. At least with a standard chamber the wads will be easier to get in the case.Thanks for the responses! They definitely have added some food for thought.
