When i was boxing up my old accura, i found a few 250gr slick load sabots. These normally shot best with 80gr powder but with pellets, i decided for the heck of it to go with a full 100gr pyrodex pellet charge.
Elevation was just right at 100 yards but a good deal to the right.
A 2" center center group is good enough for hunting but i personally want tighter than that.
A total of 6 shots through the rifle and this is what the plug looked like when i removed it for cleaning.
