that walks has fallen to chest hits from the .44, and from similar "powered" muzzleloaders. With the 3-4 hits per second possible with the canned BAR, alloy framed, 308, why bother with slowassed bolt action, when you are talking EITHER hunting or defense against big animals, hmm? If you "telescope" about 8" of the 308 can back around the barrel, and don't really care about max quietness, another 6" of can, past the muzzle of the 20" barrel, can do a lot for you. The OAL and wt will still be less than that of a 26" barreled 12 ga pump or autoloader, which many consider to be "fast handling', and lw enough to carry afield all day, in search of upland birds.
