a friend of mine knows a guy with a chronograph , i have set it up for tomorrow to go shoot some 777 and see what the results will be . here is what im going to do , i will start out with a 150 gr charge and work down to 100gr charge . i will be using the 240gr honady xtp bullet / sabot and a musket cap for ignition. the can says it will shoot 1820fps with a 100gr charge of powder . the gun im using will be a t/c blackdiamond xr .50cal
with a 26" barrel . i have shot the 130 & 140 gr charge and got 1-1/2" groups so am curious of what the speed difference is , the 140gr charge really kicks . i hope this info will help all of you out considering using the 777.
