Using 3D design and a 3D printer, I've designed these 1874 Sharps camming tools. I've been prototyping this scope version that still needs testing (since I don't have a scope.) I have never broken one of the straight versions -- and am pretty confident the amount of pressure to break one trying to seat a cartridge indicates a more serious problem. Metal or plastic -- I am sure you would stop if you were applying that much pressure and the cartridge wasn't seating.

Also, the camming tool seats from the lower section of the base of the cartridge and does not (or maybe just barely) touches the primer.

Not trying to sell them or find someone to test, just showing what can be done with 3D printing.

Same tool for iron sights. For this version - orientation does not matter - it is identical from both sides and will seat from either side.

That's pretty slick and ingenious!
