Home Forums Lever Action Central Cowboy Levers How strong are modern made steel 1873 copies?

I have a question to ask concerning this. We shoot 44 mags in revolvers with no rear head support.Now is the straight case grabbing the chamber wall? Do the old tapered WCF cases have more backthrust? I never really wanted a 73 until I picked one up and its now on the list.
Sorry for the late post but this just came to mind.
