Very nIce rifle build DF.
It looks like you still have a little extra weight here and there that could come off if needed. BUIS for a long range puncher?

I'm still in the middle of my new build. We're waiting for a barrel assy to be built and shipped, then we'll be ready to send some copper & brass down range. Barrel folks now say two more weeks to glue it up and ship.
I noticed you've gone with an ACE butt stock for this rifle. I put an ACE on one of our .450s as you suggested, it lightened things up nicely with no rattles or movement when spitting out the bigger bullets. I did have an issue with cheek weld vs eye relief with my selected long range scope and scope mounts, so i've gone back to an adjustable butt stock to help fiddle with that issue on my new rifle.

Blued steel and walnut = bird guns!
MAID,
BUIS is on there because I can. Humped my 12 pound Savage 10T last year up and down every damned hill where we hunt. It is lighter than last year's weapon. A few ounces is nothing to me.
No issues with Ace skeleton stocks for me. They fit me fine because I have freakishly long arms. The biggest issue is scope mount height. I have 4 rifles with these on them, and after that it is 3 Magpul collapsible stocks, an A2 and a Sig brace. Ace is light and fits me.
I think you and I need to go shooting some time.
JG, You know me. I am not a conformist and I know your were kidding. The boys and I have been killing animals with AR's for years. Body count is only going to get higher. My goal is to be the poster child for hunting big game with AR's. Take is easy Paker, we don't want JG to put you in timeout.
Nick, My goal is consistent shooting out to 400 yards. We have a steel range that goes to just under 600 near McCleary. I'll be practicing with it this spring and summer. It is my new training rifle, so it should see a lot of rounds down range this spring and summer.
Best thing is that 10 round mags are $16-20, while 10 round mags for my bolt gun are $45-50, the same as 4 round mags.
