Those are TC 250 grain muzzel loader sabots. I used data for a 275 grain bullet. If it doesn't kill me i'll be back with a range report later on . If i don't post one you can hold a memorial for me.

Hey, you never know what could come of this. What did you make it out of. Let us know how you made out. thanks

Well my load of 42 grains of H-110 seems to have been a bit too hot. The sabot was coming apart and the bullets were keyholing. If lee ever sends me a replacement sizing die I'll take it down 2 or 3 grains. That or i'll try loading it with unique using a cast bullet load.

Try a case full of black under those sabots and see what you get. Also, do what crosschecking you can and perhaps use a load of 4198. I suspect the H110 has too quick a pressure curve, only way to find out is to slow down the powder a little.

If those aren't high pressure sabots, they aren't gonna work, you're just gonna blow the skirts...maybe some data from the Savage smokeless muzzleloader will help. Also, the rate of twist for the 500 S&W may not be best for the .45 cal bullets, I don't remember what the twist rate is... :oops:

I have heard 1-18", but that is second hand information. I would like to know the land to land and groove to groove measuremants if someone has a .500 S&W. I have heard that the groove measurements were .500 and if they are your likely compressing the sabot too much. the sabots are designed for a .500-.504 land to land with groove measuremants around .510.

Could I get the measurements and twist rate frome somebody, please. I have a special project in mind for a .500, but I need these measurements before I buy one. I have asked on here before but now there may be a few more out there. Thanks.

Jerkface,

One easy way to see of the saboted ammo will work is to try loading just the sabot and bullet from the muzzle or by pushing it through from the breech with a ramrod. If it is too tight, that may be you problem. A "ballistic bridge" MMP sub base might also help if you are blowing the skirts on the sabots. Good luck.

most new muzzle loaders are 1-24 twist. some are 1-32. what about a cva powerbelt?

quickdtoo · « **Reply #8 on:** July 30, 2005, 01:27:31 PM »

Powerbelts aren't made to be shot in front of smokeless powder, the skirt is too thin. Magnum sabots would be needed, I'd look at the Savage smokeless data if I were trying to make something like that work.

What i used were the thompson center 250 grainers. I'll try some magnum ones if i see them for cheap.

Just an FYI for .500 S&W handloaders..

Quote

The inital run of 500 brass used pistol primers. Then SW finalized the brass to use rifle primers. The difference is the rifle primer pockets are silghtly deeper. If you seat pistol primers in them they will go too deep and may not go off. Or you will crush rifle primers attempting to get them to bottom out in pistol brass.

Now the way to stay on track is all the current brass is headstamped " SW 500 Magnum R ". The R in the headstamp indicates a rifle primer is to be used. When you order your brass make sure you get the new current " R " marked headstamp and life will be simple and good. I learned this the hard way and had to sort 1000 ct of 500 brass once. I ended up throwing out my initial pile of 500 brass because it was the old pistol primer pocket type and I kept getting it mixed up with the new rifle primer brass.

Are those saboted bullets .451 or .429? IF they are .451 and IF one of the problems is "too tight" (in addition to "too fast"), then PERHAPS using a .429 muzzleloader bullet instead would help....??

In any event, VERY interesting - thanks for being a guinea pig. :grin: Tim, you can't remember the twist rate of .45 MLs? Geez, sometimes I think you're just completely worthless. :twisted:

jerkface11 · « **Reply #12 on:** August 02, 2005, 05:55:37 AM »

they were 451 when i get my dies back i'll try it with the .429 bullets.
