Sounds like a Great trip with your son, even if no animals were seen. And when you do spot some game in the future, having not spotted and harvested one right Away, will likely just make That moment even bigger
Does he know that the rifle will be his one day yet?
Ps. I have a sporterized m98 in 6.5x57 , carrying a Schultz Larsen barrel, and I think whomever put it together to its current configuration modelled it after the obendorff Mausers in terms of stock and look.
Now even though she has a full length 24 inch barrel, she shoulders and points well, carries light, has good balance and distributes recoil well.
So Maybe Obendorf just hit a true Winner with that stock and rifle design , and i can more than understand if that's your go to, at the moment.

And that's even without the great satisfaction that I imagine carrying and using a rifle one put so much effort into making , must bring. .-)
