A 1:22" ROT is about optimum for shooting heavy conicals in a .50 caliber rifle, FWIW. Very few Traditional .50 caliber barrels come with that Fast a ROT. With any .50 caliber Rifle designed for shooting RBs, and having a ROT of 1:48", or 1:66", and grooves that are .010" deep or deeper, its going to be very difficult to get top accuracy shooting any conical that weighs more than about 380 grains, as the bullets will be too long to stabilize properly with that ROT.
I am a firm believer that NO MLER should be attempted to be made that creates the same pressures, and shoots the same powder charges and bullets as a cartridge gun of the same caliber.
Those brass casings add a LOT of strength at the breech of the gun to give the shooter a margin of safety when shooting these heavy loads.
There are some "tweener" style of MLing rifles that employ a closed ignition system that can take those pressures, but I know of no Traditional Sidelock action that can handle those massive loads with any margin of safety. You see the closed ignition systems on heavy bench rest " slug" gun rifles, that were never designed nor intended to be carried into the field for hunting.
The last thing anyone should want to see happening, while shooting a MLer, is to see the Nipple( or any other part of a rifle) come flying back off the gun towards the shooter's head.
