Sabot Affect Accuracy
#11
'Although' there was a time that TC was using Harvester as their supplier and Hornady was actually making their own but that was back their a bunch of years. I can not remember when the SST/SW hit the market but it does not seem that long ago...
This chart shows some of the different measurements....

I don't know if I am reading this post correctly but I need to ask. What diameter bullets are you shooting. If you were shooting the black sabots these are for a .451" bullet. The green Harvester sabots are for .429" bullets. that could possible be your problem. But I am not sure.

I still have the extra sabots, they were different than the MMP-24s or the short black ones that Knight use to sell...They were also different than the ones T/C supplied so it could be the ones Hornday was producing...I was shooting the 250SST/Shockwaves in .45 caliber so all the sabots were black...I'm guessing this was 8-10 years ago although once past a certain age, who knows... 
We had several discussions on here about the differences back then and how it affected accuracy...
I've still got 4-5 boxes of those T/Cs, just moved on to the .430 Hornadys and green Harvester sabots...
After I saw how sabots could change groups it just made sense to buy in bulk and simplify things...

Back in the day.... TC was marketing a black 44 cal sabot... it was made for them by Harvester under contract....
Here is a part of my sabot collection dating way back....

This morning i went sabot hunting.

It isn't apparent to me what makes them sabot on the right throw bullets helter skelter. They look about the same as the ones on the left--the Harvester smooth green. The only thing obvious to me, is i am up there shooting a way too much; there are spent sabot covering the ground. So, since i was there anyway, and wanted assurance i can hit something with the 270g Deep Curl. I fired 3 shots at 103 yard from the V2. The sabot was the Harvester smooth, the primer was the STS, and the powder was 115g BH. Them Harvester sabot on the left work much better than them sabot on the right. Why?!?

Ron,
Do the bullets sit in the different sabots the same? The ones on the right are more than likely MMP however I cannot tell the difference by the photo. I guess they are MMP because I know Cabela's sells MMP. I have seen that with the MMP's the base of the bullet does not sit flush in the sabot sometimes, depends on the bullet.

Looking at the pictures the best I can... the sabots on the left with the small teet in the middle of the powder cup... they are Harvester, the one on the right with the smooth cup are MMP, but they appear to be the older short petal plastic MMP not the HPH polymere. Just guessing
Mine are all out in storage so I grab them and look...

When placed into the Harvester sabot, the bullet sits on the bottom. When placed into the other sabot (on the right), the bullet will climb upwards with time. The mystery as to why the sabot scatters bullets, seems to answered. It only took a good question to find the issue. The sabot doesn't fit the bullet correctly.

Not necessarily.... most bullets do not sit on the bottom of MMP sabots, they are built that way. However when you push the bullet down the bore the stretching and compressing the petals will allow the bullet to seat on the bottom of the sabot. This is done to insure that the sabot, which is a whole lot lighter than the bullet, is locked tightly to the bullet and any spin imparted on the sabot is imparted on the projectile (especially in warm bores). It is the old physics rule... a body at rest tends to stay at rest....
Again in the old days... sabots would spin on the bullet and the projectile never reached the correct RPM.
To test this Ron, remove you breech plug and push the combination all the way through the bore, when it comes out of the breech it will be seated in the bottom of the petal.
