I used to have both round and square butt 34s, with 4" barrels, down to just one RB now. My experience of them as grouse getters was that they weren't accurate enough for head shots past about 10 yards, and that body shots (base of the wings) might or might not anchor them. Best ammo I found for that duty was the Winchester Silhouette shaped like a LSWC (hollow points were too destructive). Far too many grouse were able to get up and sail down into brush choked canyons, full of old logging slash. Total PITA finding them. So in a way, the 34s were good teachers about what worked, and what didn't, for shooting grouse with a revolver. I eventually went to a Model 31-1 .32 S&W Long for grouse, and later still, a 60-10 3" (with very mild loads). The wider bullets simply killed better. But I will say that the 34s are probably the most fun plinkers and teaching revolvers out there; the grandkids love them!
