Newbie here, I have a Kodiak and the the thing has been all over the place out of the box. Both calibers erratic, on a bench. Using Premier pellets from WM. New scope, and rings with blue loctite. Picatanny no creep base. Bought for critters around property but can't hit nothing. Retired LEO Rangemaster and shooting for years. This one has me stumped. I ordered HN pellets, they will be here in couple days. By the way, it has three different sounds when I shoot....a spring thud , a spring air sound, and a .22 crack with gas/smoke. Thinking about trashing it and buying a Gamo . Any advice.....
