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.
I think the harvesters are holding the gastighter behind the bullet because they are spread outmore OR they are weaker in the bootom and are flatening out against the bullet to get it going. Which do you think it is, reading the bottom of the sabots? All the petals intact, like a daisy is they way they are suppose to look and these batchesboth look fine to me. I have heard that MMP are stronger plastic than Harvester, so that may also be the difference. About an hour ago, I just ordered a bag of "short black" MMP12, MMP24, 3Petal EZ and Orange from MMP directly, $45.97 delivered, so I will have the right sabots for any combo. I have a lot of crushed rib (6 packages) and a package of regular harvester sabots. With this I can experiment around with the 300g XTP and Gold dots in my Savage. Chap
