>> I have read that the GAMO CFX has a loose or oversize barrel inside diameter. Never gave it much thought until I got two tins of Gamo Hunters from MidSouth that would not chamber in either of my Gamo Hunter 440's nor in my Mendoza. Used my calipers to check them and they were oversized plus had a dimple in the top of the dome.
>> Today I tried them in my CFX, tight but they went in without too much fuss. Will try to shoot them for accuracy soon. Think I will order some JSB Exacts in the four different diameters and see what my CFX likes.
