I've been researching this caliber lately due to ground squirrel opportunities starting to crop up on smaller parcels of land. The need for something that isn't as loud and doesn't ricochet is limiting the cartridge choices and my 22's just aren't making it. I've been seeing some posts that this cartridge is on the way to being obsolete, etc. Others have posted that Hornady is still determined to support this cartridge. So far, Savage seems to be the only mainstream gun manufacturer still making affordable rifles in this caliber. Does anybody know any more info on this caliber, etc.?
