The Ackley Improved design's steep shoulder is said to minimize the case stretching problem. I have a 30-06AI, and have had it or a very long time. I haven't had to do any trimming for length, so I think this may be true.
I had an old buddy ( who has since passed away ) and he used the standard 25-06 with the Sierra 117 grain boattails for EVERYTHING. He loaded IMR 4831 with this bullet, and pushed them pretty fast. This guy shot dozens upon dozens of big Oregon blacktails with this rifle, as well as a boatload of elk and a couple of Wyoming moose. He also had a 300WM that he shot a few elk with, but stopped using it because it was too heavy to carry and he said that didn't kill elk any better than the 25-06. He only found a couple of bullets in the animals, as most penetrated completely.
I also remember him telling me that the rifle shot well with the Hornady 117-grain factory loads, back when they sold them in their Light Magnum line of ammo. His 25-06 was the camp loaner rifle on hunts he outfitted in Sonora, and after shooting a bunch of big mule deer, he said that the bullets didn't hold together as well as the Sierra 117's. His clients also shot a fair number of coues deer with the Hornady bullet, and he said it was a real destroyer even on the smallish animals. He used the rest of that case to shoot coyotes and liked the way it demolished them. That's the story he related to me, anyway.
