Wildcats on the 460 & 500 S&W's???

[Steve E]

Has anyone saw any wildcats on the 460 & 500 S&W cases and if so how about some pic's. The 460 necked down to maybe .357 or the 500 necked down to .40 or .41. The problem of going to .40 might be suitable bullets. I guess the dies would be expensive but then again that is usually to be expected when pursuing the wildcats.

Nobody has seen any thing at all on these cases? I would have thought that the Wildcatters would have jumped on them like any other case that comes out.

I have looked @ doing some things on the 460 and 500 S&W, but other projects have come first. I am thinking 460 S&W necked to .400 (on right on pic)or .410 should be great in an Encore (no need to push it to 65,000 psi though) I have also looked to neck the 500 S&W to .429 diameter (on left in pic) .
I think that there are others necking down the 500 S&W to .475 and .458 also.

In time you likely will see W/C's come from them, but for right now, while they are something new in the world of revolvers, they are not interesting per se in the world of brass. There are many other cases that can be cut back to the same rough dimensions. Things that get grabbed real quick are cases that are really new and cannot be made from other sources.

Your correct Reed1911, I think others will do more on them later. I do think that both cases have positives to necking them down, like the 460 S&W necked down to .410 diameter.

It still can be chambered in revolvers if wanted but will shine in the Encore or SSP. I will chamber the 460/.410 in the next year in an Encore and should make a great hunting round. When I started working on this Load from a Disk gave loads for a 210gr. bullet in a 16.5" bbl of 2350-2400fps with out going over 46,500 psi.

Can the 500 be necked down to .357 very easily, like without a complicated (read expensive)form die set? That would really sizzle if you could, probably have to stay away from pistol bullets unless it was kept at lower velocities. From your handle I take it you have an AR10, I have an AR10 A-2 in 308 with a RRA Ntl. Match trigger worked over by Mr. Hollister at White Oak Precision. Talk about one sweet shooting gun. This thing shoots better than most 308 rifles I have. I regularly shoot 1 inch or less groups at 100 yds with this rifle. I am interested in the 500 necked to .357 and any info would be appreciated, I will probably get OTT to make me an Encore barrel in it.

Nope. Two things here, Biggest of all is going to be that there are not too many cases with a similar body size that can be used.
#2 Anytime you neck a cartridge down more than about 1 caliber, it is going to save a lot of headach to use several dies. If the .500 had a bunch of other cases that were in the same general size, and you already had those calibers, it would be pretty easy to use a set-up of dies on hand to neck the brass to what you want.

Now, does the idea have merit? Yes it does...

I was thinking about something along the lines of my favorite(the 357x44 Bain & Davis) but with a slightly sharper shoulder on the 500 case. Sound like something that you would be interested in?

Duplicate post, please delete.

It would certainly make and interesting cartridge. Rough est. would be 2 form dies (500 to 45, and 45 to 40), final FL die (40 to 357) and a seat die. Total cost should be about 288.00 for the full set. I would anneat the brass for sure, possibly twice depending on how the brass looks in the process. That is a pretty big drop.  If you think you might want to do it, let me know.

Steve E,
Yes it could be necked down to .357, I see Reed1911 has it correct about how to neck it down (progression). I will run it thru Load from a disk (program) and see what it could do. As to my handle Yes I have some AR-10's, 2 complete (in 6.5 WSM and .308) and 2 uppers (different bbl lengths) and as soon as I get a reamer back I will be building one based on 7 WSM necked up to .475 and .500.

P.S.
Sorry it took so long to respond I have been busy @ my day job.

[475AR10]

here is a drawing I did with Load from a disk 4.0;


I took the basic ideas from 357X44 BD and applied to 500 S&W, also went with .358 diameter for rifle bullets and could be changed to .357 if wanted. In this configuration you would look @ about 2420fps with a 180gr bullet with about 45,300psi in a 16.5" bbl. Could be fun, but there are other cartridges that will do that and more... That is the great thing about wildcatting, you build it because you want to.

Thanks 475AR10, that'll help if I choose to go any farther with this, which I'm am giving serious thought about. Like you said there are things out there that will do that and more but thats what makes wildcatin fun.

Iknow that SSK is necking the .500 down to .475 and .458, I think for the Encore.

Will that .2" neck support a 180 grain bullet or do you have to push it inside the case to make it stable? You are cutting into powder space when you have to seat the bullets deep and that would either reduce the powder capacity or raise pressures quickly. The round looks great for pistol bullets but the selection of rifle bullets goes from one at 150 grains, to two at 180 grains to 200, 220 and 250. You probably don't have the capacity for powder to push a 225 or 250 grain bullet - the 358 Winchester barel does that and the 35 Remington does a fair job up to 200 grain bullets but with the case as you make it I wouldn't think you could get more than 1900 fps with a 200 and maybe 1800 fps with the 220. That is about the lower limit for terminal performance with the 35 rifle bullets.
You have almost duplicated the 357 Herrett in volume and could probably make the two rounds identical in volume if one were to perform the AI treatment to the Herrett case straightening the case and making the shoulder a 40 degree angle and move it up just a bit. Your powder is more "square" in configuration and that might make it more accurate or consistant than the Herrett. Even if you are limited to 200 grain bullets there might be a niche to fill for a round between the 357 Maximum and the 35 Remington in a pistol case. With a 14 or 15 inch barrel it should be just about all the average shooter can handle comfortably. In an 18 inch carbine it would make a great little black bear and pig gun with either 180 or 200 grain bullets.
