Never have used the MMP sabot, but that target was punched out by my x7 at about 101yd; shooting 105g BH209; ignited by Winchester 209 primers; using the Harvester crush rib sabot . The barrel of my rifle is very tight, and that is why i use the crush rib sabot. It seems to me the MMP may be too large for my rifle, but i can't say for sure because i have never tried them. Since i have to squint real tight to focus on the front sight, one can see the bullet is plenty accurate. Didn't start shooting the gold dot until after hunting season last year, so can't testify to their ability on deer, but i will use them this coming season.
