The .17 Winchester Super Magnum is a bigger, meaner .17 rimfire created for varmint shooters who like the low price and recoil-free performance of smaller .17s but find them lacking in range, wind-bucking ability, and wallop. This round is based on a necked-down .27 nailgun (!) case and holds lots of powder, which propels either of two different 20-grain bullets at an honest 3000 fps, and a 25-grainer at 2600 fps. It is, I have on the highest authority, an honest 300-yard cartridge. As it presently stands, a box of 50 will go for $15.
