In continuance of my foray into springers. Getting ready to pull the string on a HW 97. Two questions. I notice on Krale's site there are two 97's I'm interested in. First is the Hw97K and the L. Designating the longer barrel. Will the longer barrel be quieter with a tad bit more power going long? And secondly, going back and forth between .20 and .22. I have many .22 pellets ( a few PCPs in .22). This will be for plinking and still hunting. I know thumper, for one, is not big on .22 as a caliber in springers. Any help or opinions would be welcome. Do intend to have it tuned reasonably quick and a new stock when I can.
