Sorry I didn't respond to your question sooner...I got busy doing other things.@AKDoc great hunt for sure and thanks for sharing! What rifle/scope combo/caliber was your son using?
The rifle my son used is the original A-Bolt II that I gave him when he was eleven (his first center-fire rifle). It was originally chambered for 30-06. I had it rebarreled for 338-06 when he graduated from college. In this last year he rebarreled it to a 338 Sherman.
We handload all of our center-fire ammunition. He grew-up helping me. He has his own reloading bench now in his garage and having fun playing around with the new cartridges and dialing them in at the range. He's gotten really good at it and he's an excellent shooter.
