And as far as the Sub Bases go, they were developed mostly with the Savage 10ML-II with top end smokeless powder loads in mind, and a little less so with 150gr T7 and Pyrodex loads, to protect the sabot from heat damage and provide an extra gas check to stop gas blow-by which wrecks accuracy. So in the recent past (2-3 years ago), the BBSB's could significantly improve accuracy with hot loads. As a side note: I've just trimmed the obturator cup off 28 gauge AA shotgun wads to perform the same function, as it's much cheaper!

The plastic used in current production MMP sabots has gone through several improvements since the BBSB's were introduced, and current sabots really don't need the extra protection the BBSB's provide. In fact, since the BBSB is just one more component in the bore, it's one more thing that can can go wrong and make accuracy WORSE. Current production MMP sabots don't need them, so I wouldn't bother with them.

Good luck,

Mike

BTW: Haven't you ever heard of flowers or jewelery, man?! Something for her, something for you, all is well in the world![8D] When I married my wife, she told me she wanted kids, I told her I wanted a Harley. Now 7 years later, we have two kids and I can't afford the Harley, but I wouldn't trade my kids for all the Fatboys in Milwaukee. We don't always get what we want, especially where women are concerned, but some trade-offs aren't so bad!
