6mm- Great photo man! Congrats on you/your sons success.
The irony of that story - had the same story been told but instead you changed out the '243' with a 270, 7/08, 7 Mag, etc. everyone would say, 'too light? - heck no!'
Thanks for sharing. BTW, what rifle is that, I see on 2nd glance it has a silver handle like a Ruger....but not sure since the stock looks more like a Remington or a Boyds aftermarket.
