Ok, my bad, I meant .22 Rim or .17 HMR
where to start...
.177 does not produce the smallest groups.. you are confusing group size with "hole size" or calibre size.
lighter weight makes variations worse not better - a 0.1 grain variation is a bigger percentage of 8 grains than it is of 14 grains
FAC air advantages out to 55 yards ? You kidding right ? Lets go with flatter trajectory, less wind affected, and a far greater impact energy (allowing shoulder / heart / chest shots rather than a small and potentially moving brain).
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
