Just got the refill adapter in the mail this morning and filled the talon SS I just bought last week. As far as I know it is stock, but got it used. It is .22 cal w/12″ barrel.
filled to 2900psi and shot over the chrony. Could not find any Kodiaks or JSB pellets in town, so just bought what I could find for now. Those are Benjamin 14.3gr dome pellets and an RWS brand of pointed field tips, don’t know the weight of them.
Chrony w/ power dial all the way down showed about 464 fps. Dialed to the top I was seeing about 896fps and it was pretty loud. I have it set about the 7 range and shooting 790-810fps and not quite as loud.
Have not shot a string yet to see what a curve may look like, hopefully more time tomorrow.
