So.. If I understand right the original 475 Linebaugh brass was made from cut down 45-70. The current 475 Linebaugh has a downsized rim to fit in the FA 475 cylinder. Is the RH/SRH cylinder big enough for the 45-70 rim?  |

I have a 5 shot ruger custom, that I cut down 45-70, just to try it, and they fit.
They should work on my ( being built now) 475 Maximum so I can save the few head stamped pieces of Max brass that I have.
Try one in your gun. There’s many ways to build them

475L is a perfect use for the short Hornady brass from their FTX loads.

Fits fine in my bfr. It's close but works in the Reeder 475 Redhawk. My Linebaugh is of course built for the original rim since it's from the 90's. I don't have a Ruger 480 yet.

Is the RH/SRH cylinder big enough for the 45-70 rim? On my SRH .480 one 45-70 uncut rim just touched the extractor ratchet, some others I measured will not pass and will bind.  I tried it with some native .480 brass and a chopped .475 and the 45-70 will bump the .480 rims.  |

Might have to reduce rim, just depends on your gun.

Yes. Just trim the Hornady brass, debur and load like regular.

That is an awesome idea for the 45-70 FTX brass. I'd make a mandrel for a 1/2" drill, spin the brass on the mandrel and kiss the edge of the rim with a file and call it good.

Don't need 480 brass here. Just asking the question to make sure everyone knows.

Doesn’t loading with 45-70 brass allow for a bit more powder and higher velocity?

Doesn’t loading with 45-70 brass allow for a bit more powder and higher velocity? I had to use Winchester brass mainly because it's rim is a few thousandths smaller. It does allow about a half to three-quarters grain more. Not enough for the effort if you can get the Starline. |

My understanding is that any .45-70 brass besides Winchester requires inside reaming when converted to .480 brass in order to accommodate the relatively long bullets. Can you comment on that? |

My understanding is that any .45-70 brass besides Winchester requires inside reaming when converted to .480 brass in order to accommodate the relatively long bullets. Can you comment on that? Yes brass does require reaming, even if it is Winchester for the 480 with bullets over about 330grs. In the 475 you can get by with a longer bullet. I haven't made 475 brass in 20years, but some of those are still going. Admittedly I don't shoot the 475 much and never really have. I prefer the 500 to it. Starline 475 brass is different. Even trimmed to 480, it doesn't require reaming for most bullets. Making 475 brass from Starline 45-70 doesn't require reaming for my favorite bullet, Arsenal 476-415swc. Haven't tried the Starline as a 480 yet. I don't yet own a 480, so never really messed with it too much after satisfying my curiosity when it came out. Hate cleaning the carbon ring out of the 475. |
