338 Federal Experiences? Thinking of building new AR10
Does anyone have any experience with the 338 Federal round? I’m thinking about building my next AR10 with a 338 upper versus the standard 308. I know the 338 is a necked up 308 with a slightly larger diameter bullet. I’d like to it mainly as a deer gun. But if the situation ever arises, maybe bear, elk and/or moose. I like the idea of the 338 because of the wide range of weights to choose from. Also, it’s starting to become more prevalent and is sitting on more store shelves.
What kind of distance can I expect out of the 338 Fed?
Is the 338 Fed around to stay? Or is it just a novelty round?
Or should I just stick with the tried and true 308?
What other big bore calibers should I look at?
I was originally looking at the 50 Beowulf, 450 SOCOM and/or 450 Bush but those are only 150-200yds rounds at best. The plus side of these is that all I would need is a dedicated upper for one of my AR15 lowers. But ammo availability can be a bitch. I can shoot half that distance with my 20ga and damn near that with my 50 cal smoke pole.
