Response to Pellet weight and gas-rams

Shooting Crosman .20 Premiers at 26 fpe: when shooting 21 gr .20 special pellets the energy dropped to 17 fpe. The other half of that late 1990s experinment was to shoot both pellets from a very good Sheridan which shot in the 14 fpe zone with both pellets, the 21 gr pellet doing slightly the better.
In this example the drop in power from the overweight pellet was significant from the gas ram and the msp showed the trend of a pcp with a very overweight pellet. .... Kind regards, Harry.
