OK, I've got an opinion question but first a little history of how I got to where I'm at on this. Some of ya'll will remember back in December I purchased a Rossi .243/50 cal. ML combo. Well that turned out to be a disaster, or at least beyond a 100 yards it did. It no longer resides here but now I've got a chance to get either another 243 or a 270. The main use for the rifle would be for me to coyote hunt with but it would also possibly serve a secondary purpose as my son's deer rifle. I know the 243 is plenty of rifle for deer with proper shot placement but I think the 270 might be a bit better, opinions please. One thing I would like to ask though is please keep it to these 2 calibers.
