I have a Farley action rifle that belonged to a great friend that’s no longer with us. The rifle has two barrels, one is a 6mm dasher. There was a 600 48x f class match shot with this barrel. The barrel has some rounds through it but prior to the owner passing I shot a 1 inch 5 shot group at 600 yards and the first three were half a inch. The other barrel I think is a 6.5x47?? But not positive. These barrels were chambered by Gene Bukys. Attached pics of the groups. Just the rifle and rings, no scope. Ross6905@aol.com
