Woops I jacked up my barrel

Thanks for that.

I have been looking at putting an on-board air compressor on my SUV for airing and changing tires, including using an impact wrench. I can imagine the expression on my wife and kids' faces if I ran the 30' hose into the office workbench.

Would I be nuts to start by building a .300 WSM AR?
Or should I plan on my first project being a throw-away?

The person who never made a mistake never did anything! Go for it but take your time and "enjoy the process". Any process of learning, "education" cost money but experience is the best teacher. I would plan my first project as being an absolute success, with a possibility of an expensive learning curve. This forum helps mitigate cost,

Can't get a WSM into an AR15, are you thinking AR10? Or .300 WSSM?

If .300 WSSM, you'll have to use really short, light bullets.

Sorry, an AR10 receiver. Mega? or another manufacturer preferred?

Hmmmmmm.... If I understand the AR series, I couldn't really ruin the accuracy of the rifle until I get to mating receiver and barrel, right?

I can probably get help with that from one of my shooting' buddies who makes 'em, but I would like us to have our own tools (just like I still have my dad's tools).

[woohoo]

There are a few problems with magnums in the AR10. The mags don't feed well even if you can find a RSAUM follower. The extractors are made for 308 sized cases. When the extractor moves out far enough to snap over a .535 rim it slams into the lugs of the barrel extension. If you modify the extractor to work it will be weak and break off.
You could clearance the 2 barrel extension lugs where the extractor slides through but you still need a RSAUM bolt that no one makes and the mags still don't work.
Save yourself a bunch of headaches and do something else.

Get a quality upper, lap it "carefully" if it needs it, quality barrel that fits snug in upper barrel extension, bed it with blue lock tite if you want, tighten to proper ft lb's torque, check head space, good trigger, optics, and your good to go. There is more of course but that is why building your own AR can be fun and rewarding. Building an AR isn't brain surgery but I learn something new all the time. Truth be told, the most accurate AR's I have witnessed have always had the best shooters behind them. From the targets you have sent me you are one of them.

Here is a different approach.

Yes, even my preliminary internet search shows the WSM/SAUM idea to be a non-starter.

You are too kind and I am too undeserving, but I am very lucky that we shoot with some seriously excellent shooters who are doing their best to coach.

...and those NEMOs are gorgeous. I wonder how that $100,000 titanium .308 shoots.

I've played with one of the WinMag Nemos. I wasn't as impressed as I thought I would be, and I can't figure out why. That stock is a big turnoff to me, so it could be just disappointment that they chose such a cheap looking stock carrying over. And if you are going that big, why not do it right and go with a cartridge with better ballistics, like one of the big 7mm's? BUT....Americans love their .30's!

I have no doubt that this is within your capabilities, Nukes. If I can build one, anyone can. Youtube was a great resource for me, particularly the videos from AccuracySpeaks. My seven year old nephew and I built a lower together a couple of weeks ago and had a great time. It's pretty sweet shooting a firearm you put together yourself...especially when you're seven!

Thank you for the encouragement... And what a great thing when any family does projects of any kind together! You sound like the type of man who deserves and will surely have a Very Merry Christmas!

And may God bless all of you in this Christmastide and keep you and your families safe in this coming year.

texdooug1, did you get the answer to what you were looking for? Good luck. Hopefully the impact driver can make things line up better.
