Just had a brown bear hunter show up with one and took him down to our 100 yard range to sight in. After a couple minutes of adjusting and readjusting positions and sandbags on the bench, another couple of minutes of fidgeting with turrets the first shot completely missed a 10 inch paper plate ! Another couple of minutes readjusting everything eventually resulted in a hit !
As the guide, I'm sure that's comforting.
I'll wager there was more entertainment in the ensuing days.
