That's the first I've seen of it, too.

I ran across this, moments ago.

I have an old box of 400 gr. .475 LB Hornady

It shows the velocity as 100 fps more than later versions. It was truly brutal in recoil. I had a gun failure that GNR took care of, even though it probably was no manufacturing fault. It was factory ammo back then, just too hot.

I remember back in the 1990's Seyfried and LB were taking .45-70 brass and modding it, reaming, cutting, trimming rims to clear pawl gears. Then they did the .50! It was an exciting wild time.

There was no factory ammo when I started with it. I made mine from .45-70 brass just as John told me to.

Factory ammo and brass were nice when they came along, but I always preferred my own home-made stuff.

So you didn't have to trim rims to clear the pawl gear?

Maybe that was for the FA83?

Yes. The reason for the smaller rimmed cartridges

was the diameter of the cylinder in the FA83 is smaller than the diameter of the cylinder in the 5-shot conversions.

I'm with Jim

There was no factory brass or ammo when I started playing with the 475 Linebaugh.

I still make my brass from Winchester .45-70

John devolved it first, then fearing that .348 brass would dry up, he started working on the .475

By golly your right. I didn't know Linebaugh, only through

G&A Seyfried's articles. They were a delight for sure.
