Just a quick question. I have some Winchester Jacketed Soft Point in 357, will use in a polygonal barrel. Do using these rounds risk fouling the barrel with lead?
Thx... |

NO!
I shoot, therefore I am. |

What you'll see in the barrel will be either powder or copper fouling, but it WON'T be lead.

The only jacketed ammo I have heard of that could lead foul was some of the old half jacketed swaged bullets. They actually had lead touching the bore and were typically very soft lead.

Here's a pic of the same round. I wondered, because of the large tip of exposed lead, that it might rub off on the bore. So you all don't think so?

No.
The only part that will touch the rifling will be the gilding copper. The amount of engagement in the rifling is amazingly shallow. If you ever can find a relatively intact bullet after being fired, you'll see what I mean. |

I agree ther's no chance of fouling with that JSP. For the O.P. what firearm do you have in .357 Mag with a polygonal rifling ?
I can't think of any. The Marlin 1894 Coboy has the outer octagonal barrel but the rifling is the old ballard style built for cast bullets ( the .45 Colt 1894 also has this rifling but not the .44 Mag AFAIK. ). I have a box of PMC .357 Mag 158 gr. JSPs I've been saving for no real reason except I don't enjoy shooting full house loads in my 686P with a 4" barrel Randall Do not go gentle into that good night, Old age should burn and rave at close of day; Rage, rage against the dying of the light. - Dylan Thomas |

I have a 327 TRR8. It does have the polygonal shroud, and I was under the impression that it also has polygonal rifling. Am I incorrect? Incidentally, just got back from the range with my son, shot the 327 for the every first time, 38's and those 357's. We had a blast, but I think we'd like to join an outdoor range/club. |

No. Smith and Wesson's are traditional rifling. Even if you shoot lead bullets (which I am beginning to prefer over jacketed) leadding is easily cleaned with a "Lewis Lead Removal Kit" or with a copper "Chore Boy" wrapped around a brass brush. You may consider reloading (save your brass now) because you will want to keep your revolver well fed.  Respect wildlife, use a good marinade. |

Pps:
Thanks for the info. I did read that the gun had polygonal rifling, here, at the bottom of the second page: http://www.atncorp.com/i/expert_opinion/tacrevolver_1.pdf I think I may take a look at the Lewis stuff. |

Here is another reference to the polygonal rifling from the Smith & Wesson site:

You are right, I stand corrected. With the polygonal, just make sure you clean the lead out before switching back to jacketed. With the jacketed soft points there is still no worry about leading. Respect wildlife, use a good marinade. |

Hmmm?
Wonder why the Hell they did that? Thanks for teaching an old dog, a new trick Tobar! |

Being a newb, I have no idea. What are the pros and cons of polygonal rifling? Don't Glocks use it too? |

Not wanting to hijack your thread, I posted this question over in the lounge yesterday. http://smith-wessonforum.com/eve/forums/a/tpc/f/500103904/m/9261002613 Respect wildlife, use a good marinade. |
