It's all about the pressure, bullet weight is ancillary.

I shoot 265g home cast and always have. They run @ 1200fps and so far - NO - wear in 30+ years of doing it.

Shoot any weight bullet you desire. Deal is, you have to shoot the big stuff at lower FPS.

300g @ 900fps isn't any more detrimental than a 240 @1300fps, in fact it's probably more gentle on the revolver.
