After the stellar performance I've experienced in my unregulated Huntsman .177 for informal target, rabbits, squirrels, sparrows, (many of these pests haven fallen with the Huntsmen) I'm all in on .177. Only had experience with Springers in .177 in the past. I have three .25's, wish one or two were .177 instead, considering Bantam Sniper in .177! All calibers have there place, I just learned I enjoy shooting the .177 as much as the other calibers!
