40-90BN and paper patch

[Michael Johnson]

Best I can tell you is 1f and a lot of it. The one thing the 40-90 will tell you right quick is if you don't have enough powder and compression it will foul really quick.

I use 103 grains of Swiss 1Fg with my PP 500 and 550 grain loads in a 45-2.6. I wipe between shots so I am not terribly concerned about fouling. Bigger concern is which chamber and why, also questions about the advisability of the 7 degree leade. I am leaning towards the standard factory chamber because of all the negative comments about Orville's chamber on the Shiloh forum. His chamber makes sense if you are trying to duplicate a historic firearm. I have a hard time reconciling all of the work that has been done in the last 60 years by modern rifleman against that which was done by a few individuals from 1870-1890. I am not trying to diminish the history only trying to recognize all of the many modern contributions. I am also looking at a 1/14 twist to handle 420 grain bullets to the 1000 yard line. I know what it is like shooting a 40-65 with a 1/16 twist at Silhouettes on a windy day past the turkeys.
