My SP-101 says' .357 magnum 125 grain bullet' on the barrel. I keep meaning to go in the attic and find the box and paperwork to see if there is any explanation for the ammo recommendation, but I haven't done it and I just thought about it. Anybody have a clue?

I thought (or was told at some point) that some version of the SP101 .357 was using the .38 Spec length cylinders, so longer bullets in .357 mag like 158 -180 grn cartridges could/would protrude past the front of the cylinder.
That's just what I remember. I cannot verify nor confirm it. You could always call Ruger for clarification. My barrel just states .357 magnum..

I will check that out....My Dad bought the gun years ago and I shot 5 rounds of something out of it, cleaned it, an it has been in the safe ever since. |

IIRC it was because of Viper's reason or something about the bullets being pulled from their cases beyond max length due to recoil. |

Ruger lengthened the cylinders shortly after. |

You guys nailed it.
Response: The early SP101 are stamped that way due to very light guns of that era could have recoil start to pull bullets out from cases slightly causing the cylinder not to turn.We eventually lengthened the cylinder slightly to prevent this.Ammo manufactures have also learned to crimp lighter bullets more tightly. Thank you for your interest in Ruger Firearms. |
