Yesterday my buddy and I purchased us one of the Anschutz 1517 D Classis Rifles. We could not locate the HB model at our distributor. The 1517 D Classic is exactily like the HB except the barrel is .050 smaller. I spent all day yesterday gathering up ammo for us to shoot this weekend! I managed to get all three brands of .17 to try. I ordered a Leupold 12X40 AO scope which should be here tomorrow! Now for the last couple of years I have been punching paper with .308 and .223 rifles. I am very interested to see how the .17 does. We really needed a .17 like a hole in the head but it looked like something fun to try. I will keep you posted on the group size from this coming weekend.
