I'm tuning my Stormrider II to shoot the Griffin 13 gr slugs.
I am adjusting the location of the front barrel band (which I added to the rifle).
Observe that the band position was 40, 50, 60 and 70 mm for that target. The 40mm group is stretched out vertically. The 50mm group is round. The 60mm group is stretched out vertically and the 70mm group is stretched out horizontally. I digested that and then shot this target.
You see here the group with the barrel band at 80mm is again round. So decided to try a group at 65mm to see if I could get a group which was as narrow as the one shot with the band at 60mm and as short as the one shot at 70mm. IOW a round group that was smaller than either of the others. You can see that I did. The other two groups on the target were me just fiddling with the zero.
Then I shot this target to confirm the zero.
I realize these are not impressive groups, but clearly there are sweet spots for placing that barrel band along the air tube.
Does anyone have experience finding more than one of these nodes or sweet spots on the same rifle. I'd like to further reduce that group if that is achievable. Also interested in other thoughts on tuning this particular rifle.
