DeerYou don't specify the purpose but my vote always goes to 7-08. There are enough bullet choices for just about any task and my 30 years of experience hunting with the caliber have always given me confidence in that DRT one-shot kill harvest.
I don't know why you are deciding between the two you listed but if anything else could be inserted into the conversation it would be the 6.5 Creedmoor. It's been gaining confidence in my eyes ever since I first hated with one about 3 years ago. A few pigs, an Axis Deer and several whitetails have been taken and the internal damage is impressive.
+1 25-06 is just a great deer killer.I vote for the .25-06. If you are worried about recoil the 7mm-08 still packs plenty. I have put plenty of brakes on 7-08s because the kids still don't like shooting them. The only brake I have ever put on a .25-06 is because the client thought they look "cool". There is nothing wrong with the 7-08 its a fine cartridge and works well but it just doesn't do it for me. The .25-06 however, brings a smile to my face everytime I handle one. Load that thing with 115gr Bergers at 3100fps and kill deer or anything else you want with ease and very little recoil.
This. If you are fixed on your two choices then I'd go 7/08.Split the diff...For a hunting rifle, get the kid a 260 Rem..mike in ct
