It's a nice little varmint shooter for sure. Most are set up with either a 1:14 or 1:16 twist so you really can't shoot any of the heavy bullets. It falls on it's face at about 600 yards. It shoots flat but you better be spot on with your wind calls. Another varmint killer that would keep pace with the CHeetah is the 22-250ai. Just twist the barrel at 1:8 and run a slower and heaver 75 gr bullet and it beats the CHeetah out of the gate. Or you could twist it slower and shoot the lighter bullets. It's easy to form and it's not a burden on your wallet. Check the ballistics below.
It's an older forum, with some opinions that have been debunked about barrel burning calibers, but it also has some very good information about powders and loads. I've made a note of them.
One would be tough to find a small caliber better than the .22-250. It's one of those inherently accurate rounds on the market these days that a newb can take to the range and be accurate with.
