Eyeman,
I have several 97s. Great guns, strength however is not the issue. Because of the length of the cylinder, bullets with short noses are required, unless you seat them deeply. The deep seating encroaches on powder - free space, driving up pressures, sometimes considerably AND dangerously. If your bullet has a short nose and it is seated like you would for any other revolver, the gun will handle the pressure and last longer than your lifetime ( even if you live very loooong time ).
