For my first post on the campfire, I am going to throw my hat in the ring on this one. I am not a ballistics expert, or expert on anything else for that matter. But I have owned, shot, and killed several whitetails with these 2 calibers for the last 30 years. For the most part, I have shot 120 gr. Core-lokts in the little 25 and 130 gr. Core-lokts out of the M77 ultra lite so it is almost comparing the same size bullets. I have had MOST of the deer drop in their tracks with the 25/06 while MOST of the deer shot with the 270 ran a ways. I am sure that there have been some with different experiences-but these are mine with the same type of bullet just a little difference in size/weight. So my favorite is the .25/06-it is a fine little deer cartridge.
