Well, I dont hunt with it so thats mute point.
I do shoot alot of paper for score and trail walks.
I first shot 30 gr of 3f and had real dirty barrel and a lot of unburned powder (powder burning way in front of the barrel, notice the fire forward sometime)
Milked it back to 23-25 grains and that helped.
THEN a friend was talking to me and what he hadto say made a lot of sense.....
he said to try 15 gr. so I did. have never looked back, get tight groups out to 45 yards, can turn in 47, 48 , 49 score targets with the occasional X!
Check out the fast twist rate on your barrel. 1 in 20 is pretty fast.
I shoot home cast 490s, home cut .014-.015 patches and lube this one with olive oil.
your milage may vary, but I will betit comes real close!
