Here are the chronograph results of some of my stash of .22 LR in my Smith Model 18-3. Shown are the round, the claimed muzzle velocity, then my chrono results: velocity and extreme spread over 5 rounds.
Before you ask, the accuracy winner, from a Weaver Stance and 15 yds is a 3-way tie between CCI Mini-Mag 40 gr Solids, Federal Auto-Match 40 gr & CCI Mini-Mag 36 gr HP's. All will group 6 shots in an inch at 15 yds. I had no mis-fires and all ejected well from the Smith's very tight chambers.
