A 40-50 Straight case has all the boiler room that you need for 200-yard work. It will also give you better load density.

Believe Deadeye Bly's son, Jacob, still owns a couple of national BPCR records shooting a 40-50 straight, so you are correct, even on rams. If I recall what John told me, his son only rang one ram in all the time he was shooting his 40-50 and John is looking at chambering his own High Wall in the same cartridge.

Oh, okay. Me duh. Poor guy. 40-50 SS then. New barrel. rkaires convinced me. Light bullets to get the recoil down. One of them honed GM barrels.
Joe.
Think you've made an excellent barrel choice that leaves you some good options (rechamber to 40-65 or 40-70SS or other 40cal cartridge if the mood strikes) but has one possible negative, and that being the GM honed 40cal barrel is only available in a 16" twist at the moment, which will limit your bullet choice. With the 40-50SS, that is likely to not be a problem.
Two of my shooting partners & I have rifles with the 40cal (14.5" twist) GM barrels and they are all very accurate, competitive rifles (I managed several 100-5X+ scores at 200yd last season with a 400gr bullet) so am sure the honed barrel with the slower twist will be at least as capable once you've worked up the load. As mentioned above, the Saeco 640 at 370gr may be just the ticket for the 16" twist. BACo offers a couple of Money/Spitzer molds in the same weight range.
As additional info, we all have the Win #3 1/2 contour barrel and all rifles make weight for silhouette at just under the 12#2oz limit, if that makes a difference to you. Their rifles are both CSA High Walls with 30" barrels and mine is a Hepburn with a 32" barrel. All have shotgun buttplate stocks with cheekpieces.
Keep us posted. Should be an excellent rifle.
