Man CHAP, that's a fine group with the TC Shockwave (ain't nothing wrong with the SSTs either).
You may be right about tighter sabots = tighter groups in the Savage.
The TC SW, it was very difficult to get the bullet loaded. I had to use 2 hands and really force it.
In my Mustang, which has a loose bore for a 50 caliber, neither the Harvesters nor the MMPs are really tight. The Harvesters are the looser of the two (I can easily ram them home with one hand) and they shootbetter than the tighter MMPs.
Here's an intersting finding. The bases of the fired Harvesters were clearly larger than the bases of the fired MMPs (see picture). The Harvesters measured .561, .563 and .565, and the MMPs measured .512, .514 and .521.
