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...
