Hmmm... well, if I can afford to buy the smaller bullets I will try em anhow, but for now I will probably buy whatever is cheapest ( till I can get my loading dies, then I will taylor a round fer this with some light slugs ) all I have at present are some 150gr corelocts I hunted deer with... hope it dont blow the critter up too badly! *G* anyhow I checked out those sounds, and some of the cotontail calls are fairly easy with my call, although I had to completely rethink how I hold it in my mouth. I will let you guys know how well ( or not so well) I do once I can go out and try it on the real thing.
