Ive finally got my transfer port adjuster working awesome on my uragan. And what a suprise I got shooting at 710fps. Unreal accuracy at 50 yards and in. Its honestly one single .300 hole. So far ive taken 3 jacks, 8 ground squirrels and several pigeons. It knocks them flat, so if anyone has any doubts on lower speeds/energy on a .30 dont hesitate! I shot a tin of pellets and can probably get one more tin through it before a refill. Anyone else shooting the .30 pellets slow?
