OK, went to buy more 777pellets and couldn't bring myself to spend the extra money to buy 50 grain box and 30 grain box to try different loads on my gun. This is the first time I've used powder and just wanted to ask if I need to do anything different?

50 Caliber New Frontier, have used 100 & 150 Grain charge w/ 777 pellets if I measure 100 grains with the CVA 4 in 1 loading tool will that be close to the same charge?
