I used a 25-06 for over thirty years and harvested tons of Deer with it. Loved it but I am now shooting a 7-08 and love it even more. Both are great cartridges but with the 20 inch bbl, go with the 7-08. My Daughter has a Tikka compact in 7-08 and besides the Deer she has taken with it it will shoot under and inch group with what ever you put in it.
