I shoot 3 sometimes but here lately only 2 as it seems to work fine .
A good friend had a Knight and he/we were shooting 3 in it and kept getting blowback in the face more dust than particles . seems 777 is not recomended in most guns as a 3 pill load . loose powder to 150 is OK but pills may not be . I got that from the manf. of 777 when i called them .
My gun is the encore also ss wood stock , lupo. scope , and yea i stopped using 3 after the call .
