Hey all new guy here from western Oregon. I've been planning to build myself a custom 50 for a couple years now, and today I bought a new BAT model EX. When on the phone with the knowledgeable folks at BAT machine, they suggested I give serious consideration to .416 Barrett instead. I admit that while I am aware of the cartridge, I've never researched it much, so that's what I'm doing now. For those who have interest in the big stuff, which would you build and why? This would be just a "toy" as I'm not a competition rifle shooter, just a shooting enthusiast that likes to tinker...
