Reelamin, my B Diamond is the same way. By the third shot, I'm really ramming that sabot to get it down. It's that first few inches too. For me, it's a necessary evil, because the first shot (with a clean or swabbed barrel) is almost always a flyer but the second and third shot usually touch or are within an inch at 50 yds. I made a nice little palm saver out of some wood for this reason. I'll shoot it once before hunting and plan on a tough reload if need be. Shooting T/C 300 grain bonded super glide sabots w/ 110 volume of triple 7. I'll be honest too, the recoil w/ that load kicks like a mule and I really start feeling it after two groups of three. I must be getting "seasoned" though, because I shot four groups of three this weekend and it was the first time I didn't wind up w/ a nasty purple and yellow bruise.
