Which way did you go on this Big G? I was thinking (as I’m catching up on everything here…..gone too long!) that for a bolt action, young person, and not jumpy over the recoil, you’ve got a decent offering here. I’d choose the 270 or 308. Readily available ammo and really Ford vs. Chevy, ballistically speaking. I own guns in both calibers and the 150gr. 270 rounds are about identical to 150gr. 308 rounds. Curiously though, the 308 maintains better energy at longer range though? Not sure why that would be but I use both on whitetails cuz they really are a horse a piece. For shorter, thicker conditions, I uprade to a 180gr. 308. Hardly a difference in accuracy at 100yds and it maintains good energy while slowing the velocity, which helps in the expansion reliabilities of the round. Either way, better suited for young hunters are both the 270 and 308, and just as deadly no matter the age we become! If long range shooting is the norm, the .06 and 7mm become the better tools, according to preference of the individual.
