After many boxes and brands of sabots, I finally have a slug gun that I confident with.
The issued stock is temperature sensitive, black ijection molded plastic expands and shrinks with heat, especially if laying in the sun. Results varied because of this.
Went to a Boyds platinum stock, laminated in a nutmeg color. Steel bed the lug. Federal Blue Box 2 3/4 inch, 7/8 ounce slug. 100 yards 2.0 inchgroup.
I set this at 2 inches high at 50, it drops to 2 inches at 100. Up here in the northeast thats more than 99.9% of the situations to kill a deer.

Laminated wood is perferred by bench gun and f class shooters. Anyone else have similar results?
