Have any of you knowledgeable pistol hunters heard of the ".44-45" caliber? I think that is what it is called. Basically a .44 magnum with a longer casing, i.e. a .44 magnum-magnum. If so what do you think of it for deer hunting? A friend of mine swears by it, says it brings considerably more velocity and eeffective range than a .44 mag.
I am thinking of having my Thompson Contender G2 with a 14" barril bored out from .44 mag to .44-45. I understand that I will still be able to shoot .44 mags in it just like you can shoot .38s in a .357 mag. pistol.
I should mention that where I hunt (Illinois) it is illegal to hunt deer with calibers that have a case length longer than 1.4" if they have a tapered neck but there is no case length limit to flat walled cartridges. This is why this caliber is of particular interest to me vs., for instance, a 30-30 which would not be legal here.
