Well - I don’t have great self control. I went to a gun store to check out rifles for my son and ended up buying two guns today. I got a Model 70 Compact in 7mm-08 for my son as his first rifle (his birthday is in a few weeks) and bought the Model 70 Extreme Weather in .300 Win Mag for myself.
With my .270 and .300 Win Mag I feel I’m covered for anything I might hunt and my son has a rifle he can grow into that covers him from whitetail on up to antelope, mule deer and elk as he starts hunting more.
Do what you can to limit recoil for your son (get a good recoil pad and consider reduced recoil loads). The 7mm-08 is not a hard kicker, but it can slap you pretty good in a light gun. I have a 7mm-08 that seemed to have a decent recoil pad, but I found it kicking more than I thought that little cartridge could, it was downright unpleasant on the bench in a t shirt. I have far harder kickers (with good recoil pads and better stock fit, that I'd prefer shooting to that lil 7-08).
Thanks - I’m getting a few adjustments made to the gun to fit him better and they are putting on a better recoil pad as well. He definitely will be shooting reduced recoil loads. For the range and even when he starts going after whitetail and hogs he will never have a shot more than about 70-80 yards to start so those will work there too.
As he gets bigger and stronger he can start using regular loads and hopefully use this gun on western game once he is old enough.
