That saying needs to be repeated, repeated and repeated---tight load= tight groups. I also shoot the Crushed rib in my Omega and Knight Disc Origonal. I have a bag of every kind of MMP sabot to try with different guns but I like the crushed rib the best for overall loading pressure, I buy the Crushed rib from MidSouth Shooter's supply. I buy the MMPs direct from MMP,http://www.mmpsabots.com/. I believe finding he right sabot for a given bullet you want to shoot is as important as finding the right powder load.Bullet design is very important to accuracy also, for example the 300g TC SW and the 275g Parker Ballistic Extreme with supplied sabot shot great out of my Savage, but the Barnes TMZ did not for example. Over on Doug's Savage Forum, several guys rough up the Barnes TMZ by rolling them between two files, this makes them slight larger and grips the sabot better and they get excellent accuracy. I don't really want to mess with all that, so I take the "tight sabot approach" to increasing accuracy.

You would be wise to Print to PDF Sabotloaders MMP descriptions of each of the MMP Sabots, you can download a free PDFwriter here: http://www.cutepdf.com/

Bottom line would say this based on my experience:

tight sabot + right load= <1.5"groups at 100 yards.
