I had a .45 caliber " carbine " with a 25 inch barrel. I sold it. I hunt with a .50 caliber full-stock with a 39 inch barrel. I don't have anything against half stock guns, however, but I think using a short barrel ( under 28 inches) is counter-productive, particularly if you are shooting PRB.
I know a man who has severe physical limitations on how much weight he can carry, and how much recoil he can now tolerate. He has made a zipgun to shoot .40 caliber pistol bullets, with a light charge, that will give him both accuracy and killing power out at 50 yards, the longest distance he could see a deer from his usually tree stand. He also put a small scope on it. The gun weighs less than 6 lbs. but because of the light bullet( 185 grains) and the powder charge he uses, it does not recoil enough to hurt him. The barrel is very short- to cut down the weight of the gun.
This is an example of a special gun( he could not get the weight limitations to his desired "specs" using a traditional sidelock, or underhammer action, BTW.) made to allow a fine gentleman hunter to continue to hunt deer in his old age, when his physical limitations would prevent him from hunting otherwise. He has killed hundreds of deer in his life, and is quite a good enough shooter to take head or neck shots with his little gun. He also has enough discipline as a shooter, and hunter, to pass on chancey shots. If he fires, he will make meat. The gun is a " half stock" as those guns usually are, built on a break-open action. But the light weight, short barrel, and small caliber( He could not legally use it in Illinois, for instance) were not designed to let him " bust brush " with his rifle. He walks game trails to get around brush, rather than busting through it. If he could have made a longer barrel gun, with a full stock, that met his weight limitations, he would be shooting it. :hmm: :thumbsup:
