In The last 35 years of successful deer hunting in the upper Midwest, Nebraska, Wyomng, Colorado. Etc. I love the Hornady 120 grain bullets in 25-06. Between my sons, a close friend and I. We have taken over 135 mule deer. Over 100 with Hornady 120 grain 25-05. When the kids were younger we used one rifle with three sons and we took turns so Dad could train the kids in the hunt, not just the kill. Fairly light in recoil too. When boys got older, they went to 25-06 as they trusted this round. Daughter came along and she loves her Ultra too. Wife has a custom 6.5X55 Swede. Nice light rifle. Used to use a Mark X in 25-06. Bought the Ultra in 25-06 and it took a little work to get the accuracy where I wanted it. It will group about 3/4" to 7/8" all day now if I do my part. The big thing I found was the need to seat the bullets out and that helped to a degree. Next thing that really tightened up the groups was to crimp the bullets with a seperate crimping die.
As to the talk between the 7-08 or 25-06. Out west you will not see many of the 7-08. They do not compare at long range. Since I mentioned the number, the longest shot I have seen and it was a one shot kill, was 437 measured yards with the 120 Hornady. Bullet passed thru and deer went about 2 steps and down.
Overall for varmit, deer, elk, make mine a 25-06. Thanks for letting me share my viewpoint.
Shoot straight and know thy target!
