I too have some reservations about a 'wildcat' in any rifle, let alone a DR originally designed for low pressure cartridges. The 32-40, which started life as a BP cartridge, and which is a more traditional DR chambering is a safer choice than most, but one should always be careful about using any rifle where it hasn't been proofed for a particular load, and when in doubt, load down, not up. I now turn the soapbox, as oupa terms it, over to the next party. Dave
