I've killed 51 elk and four moose in 46 years, with a .30-06, .308, .284, 7mm-08, and .25-06. I've never used a premium bullet, and shot them with nothing larger than a 150 grain bullet in the 30 calibers. I have lost none, and none have gone more than 40 yards. I use 120 grain bullets in my .25-06 and 130 grain bullets in my 7mm-08, and elk die just as quickly after being shot with the .25-06 and the 7mm-08 as with the 30 calibers. After helping hunters at sight-in days, I can tell you that most of the people using larger calibers can't shoot them well, and some flinch just thinking of shooting the rifle. You are doing kids, women, and recoil-shy men a favor by introducing them to hunting with smaller calibers, and not handicapping their ability to kill anything up to and including moose, regardless of what those who favor magnums tell you.
