The pressures are higher in the .327 federal. I think they are 45,000 lbf/in2 in the .327 and 36,000 lbf/in2 in the .44 rem magnum, which is chambered in the marlin 1894. However, I would estimate that the actual bolt thrust, in pounds, from the .327 would be less than the .44 mag. The other consideration would be the hoop stress on the barrel in the chamber area, but the barrel metal would be thicker with the .327.

I think it is easy to ream out a .32 H&R chamber to .327. The conversion would also require that you elongate the loading port in the tubular magazine. Whether the existing lifter would work with the longer .327, I don't know, but it is interesting to speculate. Do we have any mechanical engineers/machinists here?
