I always read that the original 1873's were considered weak actions, and only blackpowder equivalent loads should be shot in them. I notice now there are some very attractive 1873 replicas out there, in useful calibers like .45 Colt. How strong are these modern reproductions? I have plenty of high powered rifles, and am not trying to make a .348 Winchester out of it, but it would be nice to be able to shoot "safe in Ruger" equivalent loads out of one.

Thanks!
