I find this the praise of the Sheridan F surprising really. Sheridan was locked into its barrel soldered to a full length tube from its pumper for some reason? There is no need for a tube that long for a CO2 rifle unless it’s bulk filled? Looks odd really. You see the exquisite Howa 55G and the Crosman 160 designed a rifle from the ground up for CO2 and the tube is shorten to accommodate the CO2 cartridges. The result a long free barrel looks like a normal rifle? The Sheridan looks like a pumper when there is really no inherent elegance in that? Plus the fact that it is probably the most inefficient CO2 rifle ever made?
