so how strong is the action on a Baikal? .45-70 isn't a wildly high pressure cartridge but 30-06 is a pretty hot little round. I wonder how much more abuse the back end could take (replacing everything but the receiver, I mean). I know the largest amount of gas pressure will be going forward and out so it might be suitable for a meaner build, or even keeping the existing cartridge and perhaps sleeving the barrels and making them look better at the very least
