curious if the rifles chambered in 475 Linebaugh, reliably shoot 480 Ruger as well???

[Fowler]

I cant imagine they wouldn't although I'm not sure I would want to crud up the chamber with the shorter case and then go back to the longer 475 case, revolver chambers are fun enough to try and clean properly from that carbon and lead build up, a levergun would be a different sort of fun...

[magnumwheelman]

Right now I only shoot 480... so it's possible that if the money fell in my lap, that it would be a dedicated 480 rifle... albeit a very expensive 480... ( If Ruger would get to work on that one )

which brings up an interesting point... I'm sure some powders "foul" more than others, so there is likely a powder choice for revolver cartridges that has little to no fouling, for use in shorter cartridges... my old Gun Smith buddy really liked Unique because of it's versatility, but I think that is one of the most fouling of pistol powders, so one may not want to use it, for example in a 38 Special, that is regularly fired in a 357 magnum revolver

I know in my FA83 shooting cast bullets and traditional lubed bullets, especially good softer lubes such as LBT Blue I would get a ring of lube on the mouth of the case. The issue has pretty much gone away since I pretty much PC all my bullets now but I shoot 480 in a 480 cylinder and 475 in the 475 cylinder (or would except it hasnt been in the gun in 10-12 years).

I admit to shooting lots of 38sp in my 357 and dont really get in there and clean the crud out but then I also dont really lean on my 357 loads either so.

Now if you just stuck to 480 brass forever you wouldnt have an issue either, just saying, I know more than one FA 454 that has been shot for years and years and hasnt seen a 454 case in that time...

Using a different example, BHA says the 460 will not cycle 454 or 45 Colt but you can single feed them. But the 454 will supposedly cycle some 45 Colt rounds. I'm sure it's more of a bullet nose length/profile question. So with that in mind I would think that the 475 version would cycle the 480s as long as the bullet length/profile feeds well in the action. The cartridge length difference is about the same difference between the 475/480 and the 454/45 - .110". I've only shot 454 in mine and haven't tried the 45 colt in it yet.

I have never tried to use 480s in my 475, so I can't help.

My BHA model 9pcycles 454 better than 460 rounds. My BHA model 90A 454 cycles both 454 and 45 colt equally well.
I just received my BHA model 89B 475 today, as soon as I can, I'll try some 480 and give feedback.

[cowpuncher]

The BHA 89B 475L went outside yesterday. It cycles 475 and 480 equally well. I love everything about these rifles other than the Loooong wait times.
Hopefully they will offer them in 50 Alaskan at some point.

Loving the new BHA 475L, it wallops the heck outta 1/2" plate swingers at 100 yards!
