Just Wondering:40-82 Silhouette diagram

[SgtDog0311]

Kurt, Mike, Thanks for the further replys. I did have a Rhoades drawing... was trying to collect several and stack them up for comparison. Lacked the 40-82 Silhouette but it dawned on me that Tom Myers software might have it and sure enough he had a modified version that I can get dimensions from and make a drawing.

I had a plan for a Ballard parts-gun with a barrel ready for that purpose and was considering the Silhouette for that one. A parts gun wouldn't bother me to chamber in a non-ballard chambering. Plans change!

Today I just took receipt of a Marlin Ballard #5 Pacific in 40-85 Ballard. Spent the evening dismantling and cleaning the bore and chamber. Bore looks very servicable but the chamber looks like someone kept sticking brass and then digging it out so the chamber is gonna have to be cleaned up, especially the recess for the rim. But the chamber walls have some fairly severe gouges running with the chamber direction. I suspect even cleaned up the chamber walls will still leave recesses deep enough to effect extraction. If so, I may have to do recamber this one even though that was not the plan.

I personally like the compound leade with something shallower than the 45 degree transition. Maybe I can cover that ground with Dave Crossno but I imagine he is using the more common 45. But if I'm reading Dutcher right his chamber would be an option.

I have a chamber cast to do as well as a lot of study of options before I rechamber an original Ballard.

Thanks for the help.
