After years of being a Minute of Moose, Deer, Bear, Bunny etc guy. I've finally joined the MOA gang and I done it with, of all things, a muzzleloader!!!

Firearm: TC Omega w/ a 3x9x40 Bushnell Banner Dusk to Dawn w/Circle X Reticle (power set at 7.5x).
Load: 110 gr 2F T7, 209 Winchester Primer, 300 gr, .451 Cal Nosler Partition w/ supplied Sabot.
Weather: Overcast w/ misty rain, light breeze head on.
Range: 100 yds lasered, shot off a bench.

I don't know if I measured the target correctly but this is how I did it. The holes were not crisp so I measured to the outside edge of the gray area around the hole. Largest spread was 1 inch minus the .451 cal = a .549" group (edit: thanks wabi)? If nothing else it's a minimum 1" group.
