All I can tell you is that I could only put a dozen or so Remington 405gn rounds thru my Marlin 1895 45.70 before having enough, Bruised and sore. After installing the limbsaver (fitted pad, not the slip on) I put 40 rounds of PMC HA +p+ (2200fps 3100 lbs energy) thru it a few weeks ago with no bruising or tenderness. I was so impressed I took everything to the gun smith for fitting with limbsavers. I don't see how you could go wrong with a limbsaver.
