Me too on the 7mm-08. I started my son, then 9, with a stainless T3. I loaded down for him then adopted the rifle when he wanted a .30-06. I load max charges with 140 Partitions and Accubonds.
All of the following were one shot kills:
Three of the five bucks hanging died from the -08. Closest shot was 175, farthest was 541 yards.
My dad's 5x5, 225 yards.
Spike bull, 346 yards.
Speed goat, 313 yards
There are several more but you get the idea.
