I've taken more than a few deer with a rem 1 187 30" back in Wisconsin in a shotgun only county. Just a front bead site. Never ever had to reach out over 50 yards, can't imagine having an opportunity for a 100 yard shot.
Did that once on .223 brass using an RCBS bench top primer. Clamped to a coffee table in the family room while watching tv. It wakes you up! Pretty flames to.
