T7,

I really think I remember those tan colored sabots - I beleive they are actually the older ones, and the 50-45's were another ulgly washed out color but I can not remember color it was. I am all out of the older Sabots - the newer Nosler's are 50-44's a washed out orange color 50-45's Black and 54-45's a faded out red color. These are the new colors. That is why I am having a problem matching up what company might make Nosler sabot no other company has their ugly/faded colors. Same for TC Mag Express sabots they have changed colors also their 50-44's use to be black now they are green and their 50-45's were another color but now they are red. The older TC Mags worked well in my guns but the new ones are a bit tighter.

Right now on the counter to my right I have 21 different sabots lined up looking to make some comparisons. The only definite one I come up with right now is a green Hornady and an older green MMP are the same. The TC mag Green 50-44 is different than either of those. The green Harvester 50-44 does not match up with any of the other green 50-44's.

I have taken some pictures and I will try to post them and some comparisons. In my guns the Nosler's are the easiest ones to get down and appear to be the thinnest. I am going to try to mic some of the petals, but I am not an engineer so I do not know how qualified I am, but I should be able to satisfy my curiosity.

Knight sabots are pretty easy to pick out the have the largest gaps between petals. New MMP HPH sabots are the tallest of the bunch - taller than any of the others. Well anyway I will do some more comparing...

I find trying to measure sabots thickness is difficult if not impossible as some if not all seem to have thinner petals near the top but taper to thicker at the bottom and when the bullet is in the sabot it is usually slightly off the base of the sabot. When the bullet is pushed with the ramrod it forces it to the bottom of the sabot and into the thicker section making the OD larger. Generally Harvester sabots seem to be easier to load in my Omega which is real tight and most sabots won't go down with all my weight on the ramrod. Unfortunately I only weigh 158 lbs. When the sabots load that hard I find it nearly impossible to determine what compression I am putting on the powder charge and cannot get decent shot to shot comparison. Powerbelts shoot more consistently for me and I am sure it is because I can seat the bullet on the powder the same each time.
