Hey, thanks to all for your replies. Forgive me, I didn't mean to get everyone so excited. I never actually planned to do this; I just wanted to see if it was something that anyone else ever heard of, and if so, how it worked out. I just though it might add a little extra versatility to the .45/70 if you find the need to take something smaller than a deer. (To tell the truth, I've never even fired a .410).<br>To my way of thinking, the rifle's chamber will certainly contain the pressure of the little shotshell, (if the shell/chamber dimensions were close enough to keep the shotshell from rupturing and spitting gas out of the action of the rifle), though I agree that accuracy would be pretty bad. I know I'd feel somewhat "overgunned' by using a 300/400 grain bullet out of a .45/70 to take a squirrel or a bunny. (I imagine I'd walk over to where the critter was only to find a fur-lined hole in the ground). <br>Cyberraven, I agree with what you say about not needing food in a short-term 'ordeal'. Like most Americans, I carry enough extra calories around my belly to carry me for a week or two. For something a little longer, I keep an old 20 gauge H&R Trapper single-barrel handy, with a few boxes of no. 6's. I figure that will certainly help keep my cooking pot full, and do it very cheaply. I think it cost me $69 years ago, so if it gets lost or stolen, it's not that big a deal.<br>
