@Silent shot - I also have a Krait standard in .177. I shoot mostly H&N Baracuda Extreme Hunter in it at 1030fps. I also shoot 10.03 4.51mm KO slugs as well as JSB 10.03 pellets. The speed drops on both, but I just adjust my scope (I have a digital scope on the gun so I change the profile for what I'm shooting) and go about shooting. My gun likes the KOs and is very accurate with them, but not "target competition" accurate! I shoot pests with this gun out to 100 yards - smaller ones like squirrels, rabbits, and starlings and have no problem dropping them in one shot. I use the Krait L .25 for longer and larger pest shots.
