Fritz, FYI...I wasn't implying that 90grns Goex FFg was the magic charge, it's just my charge...in fact, when I first decided to set up a .45 for maxi-hunters, I simply started with 90grns from general past experience, knowing it would be in the ballpark...but it gave such great cloverleafs at 50yds just sitting in a chair simulating a treestand, that I never bothered trying any other charges...if your 100grn charge is accurate, you probably should just stay with it
