Shot various groups today with my .177 Brocock Bantam at 52 yards, no wind. It became apparent that as I lowered the velocity, the groups tightened up. I'd like to get the JSB Heavy 10.3 gr. down to 885 to 890 fps, and I think the group size will shrink to dime size. Unfortunately, the Bantam does not have an HST adjustment, just the speed knob on the side with High, Medium, and Low. I didn't use low since it drops the speed over 140 fps from High. The groups were the JSB Exact Heavy 10.34, the JSB "old" Monster 13.4, and the H&N Barracuda 10.65. See five shot groups below. Velocity was with the speed adjust on High and them Medium for each pellet. Best groups were the JSB Heavy and H&N Barracuda om Medium, pretty much the same spread.
