480 Ruger & 475 Linebaugh shotshell loads?

[naphtali]

Does any manufacturer sell 480 Ruger and/or 475 Linebaugh shotshell loads? If none does, has anyone a procedure to make them using #12 or #9 shot? I prefer to take advantage of the cartridges' overall lengths -- in a similar fashion to Speer's capsuling of shot -- rather than limit payload to what fits within the case proper.

There are no factory loads that I'm aware of.
However, I make snake loads for 32 mag and 41 mag by using 2 opposing gas checks to contain the shot. 30 cal and 416 GCs respectively. I use No 12 shot and get 70 gr in the 32 and 110 in the 41. You can also use a RB in place of the top GC but you lose a little shot capacity. On close range snakes, the GCs do as much damage as the shot.

I don't see why this approach wouldn't work in the 475. Not sure what you planning to use 'em on but mine have been proven on the local moccasin population.

Gadzooks Batman! Shades of a Paradox! Since the 475 is based on the 45-70 a stepper with a Ruger 475 (that unlike the FA will hold the large rim of the 45-70 brass) and lots of money might have an extra cylinder with no throats made. Then just trim 45-70 cases to fit.. .

How is 45-70 brass reshaped (??) forward of the revolver cases' to fit revolver chambers? Turning rims to SAAMI specifications would not be an issue, though. . . . Having keyboarded that, I'll check 45-70 brass. What's the possibility of a drop-in fit?

Here's a thought I have kicking around in the ol meat computer for a while:

Take 45-70 brass, trim to cylinder length, and jam all but the bottom 1.35" of it into a "tight" 45 acp carbide size die. (.476 - should be throat size) Let the shoulders fire form if needed, use gas checks or overshot cards for a .45 caliber, crimp end of case with a .45 roll crimp over a gas check.

IIRC, the same concept has been applied to Bowen's 44 paradox using 500 S&W brass, and that letting the shot charge go lower in the case than the shoulder had no ill effect.

Won't you need the 444 Marlin cases for the 44 based paradox?.... I think the 475 will need the 45-70 case.... So far as the forming and all I haven't a clue... My 475s use the small rim 475 case.

[Aggie01]

In the case I was talking about above, the Bowen 44 paradox was using .45 colt chambers. Soft lead only for solid projectiles. (it swages down from .452 to .43 to go out)
Shot column diameter matches bore diameter.

It won't in my proposed 45-70 variant, but, you dont have to get a new cylinder.
Also, you don't want shot column dia to match bore dia in a fully rifled barrel. It will impart too much spin.
I bet someone here has a TC 45/410 barrel - the wad is loose in there till it hits the choke.

Resurrecting this in hopes someone has tried making 475 shotshells? If so, wondering what powder and charge? Seems the opposing gas checks would work best?

Perfect, thank you!

45MAN, is working on some, using a concave die I made for the mouth crimping operation, and some Hornady 4570 brass.

Made up shotshells today for both the 475 and 500 Linebaugh. Used 5 grains of Unique in the 475 and 6 grains in the 500. Put a thin cardboard wad over the powder, filled the case with shot, seated a gascheck upside down over the shot and crimped it in place. Worked great and really peppered a paper plate at 12 feet.

gjn: YOUR POWDER CHARGES SOUND ANEMIC. IN A 480 RUGER CASE I TRIED 6grs OF UNIQUE (150grs OF #8 SHOT M/L) AND IT WAS TOO ANEMIC, SO I WENT TO 7.5 grs OF UNIQUE AND BINGO. I USE DISCS CUT OUT FROM THE SIDES OF FOLGERS PLASTIC COFFEE CANS OVER THE POWDER AND OVER THE SHOT, CRIMP AND ADD SOME GLUE. MAYBE COULD USE A LESS STOUT MATERIAL FOR THE DISC OVER POWDER, PREFER A STOUT DISC OVER THE SHOT. I TRIED USING 475 GASCHECKS BUT COULD NOT GET THEM TO SEAT. NEXT UP, WHEN I GET THE STUFF, I WILL TRY TO LOAD UP SOME CYLINDER LENGTH SHOT SHELLS FOR THE 480 USING SOME TRIMMED DOWN 45-70 CASES, A PROCESS TRAPR USES A LOT IN A VARIETY OF CALIBERS.

Cheap sources for 480/475 gas checks ? I've used thin cardboard between the powder and shot and plastic from a milf jug or coffee can lid for the over wad, top. Am thinking the gas check idea might be better, easier.
