Hi folks,

thanks,
Scott |

Yes it is safe in any constriction. Just like lead. |

I have used boss copper plated bismuth through both modified and full choke in vintage side by sides without issue |

We know copper won't hurt barrel walls on old guns from late 1800's.
Do we know if Bismuth will not harm barrel walls on old guns?
Do we know if Bismuth will increase pressure over the same lead loads? |

Bismuth isn't hurting the barrels on my old Parker, and they're Damascus.
Chamber pressure is determined by load recipe, not shot type. You can load a variety of pressure levels with a variety of shot types. Choose data compatible with your gun. |

Bismuth is safe for use in vintage guns.
As a sound rule one should use tested data.
Substituting Bismuth for lead using lead data is unnecessary. There is plenty of 16ga Bismuth data out.
Using the same weight of bismuth as lead will result in greater load volume and will likely change the pressure generated. |

Do y'all order the Boss loads with lower muzzle velocities (less pressure) ?
I know that i mainly shoot lead loads out of my older shotguns that are generally less than 1200fps muzzle v.
Boss loads are advertised as hotter than that |

I would if I was buying for my vintage guns, but I reload. Lower velocity is about keeping the wood safe. Lower pressure is about keeping you safe. Not every low velocity load is low pressure, & vice versa.
Older guns were made to lower pressure standards, and there is always the possibility of barrel problems like pitting or thinner barrels. You should always have a new to you gun checked out by a competent gunsmith. Barrels tend to blow up by your hand or closer. Low pressure loads does not always mean safe in your particular gun. People before you may have honed the barrels to shine them up which makes them thinner, or they lengthen the chambers which amounts to thinner barrels near your face.
Velocity & recoil can stress the wood enough to break it. Not pleasant but nothing like a burst barrel. Err on the side of caution. |
