I had a chance today to shoot the Wolf Drilling. It took me 4 shotgun shots to figre out the point of impact for the barrels but more importantly was the rifle. This is the fist time I have shot a gun that is setup for the ammo I am using. For this gun I went with the RWS Brenneke TUG. The fist shot was 2 inches low at 35 yards. I mistakenly adjusted the scope up 16 clicks to compensate. At 100 yards the fist shot was about 10 inches high, so I adjusted the scope down 16 licks. After letting the barrel cool down the 3rd shot was 1.5 inches high. If I had not touched the scope adjustments the rifle wold have been spot on.
