On My Way TO Yet ANOTHER Build

[NRAhighpowershooter]

Well.. I WAS planning on buying a Reminton XP-100(i use to own one and am still kicking myself for getting rid of it 12yrs ago) but.. then I decided to build a varmit rig instead... I already have a OLL sitting here as well as a bare flat top.. SOooo... I just got off the phone from White Oak and ordered a 24" SS 1-12 barrel and float tube and I already have 200rnds of virgin winchester brass....and a spare Jewel trigger sitting here... now.. for optics.... I plan on ordering a Leupold VX-II 6-18X 40mm (fine duplex) scope... my only indecision is rings.... high or medium??? I'm going to use a colt style cheek rest to get the right Mk-I Mod-0 to scope alignment.

I'd say of the parts at least...but I know you'd want pics of my wife instead

get a promag 1 peice scope mount, i just got mine and its really nice! it puts the scope exactley where its supposed to be, and it isnt expensive either, its in the $50 range.

I have set of Leupold QRW 1" Rings holding up A Nikon Buckmaster (for now) and it only has about 3/8" between the scope and the upper. I don't know if this helps any or not...

These are the rings I have:

I just sold an XP100 last summer. It was an original 15" mid trigger gun chambered in 223 with a LER Burris 7X scope that I advertised on here for a week with no luck. I then sold it on another board in one day.

You got me thinking about building up an OLL. I've got 3 LCWs that I bought awhile back and stuck in a drawer and haven't looked at since I brought them home from the dealer. I think I may set one up for a slow fire gun: regular range practice for offhand and use it for 1000 yard service rifle matches, midrange 3x600 matches, and what not.

I like the high rings. Sounds like a pretty nice setup. My WOA barreled SPR is a sweet shooter...they seem to put out good barrels.

Yes, they do. From what I understand, they use Wilson blanks. You don't think of Wilson as "Tier 1" barrels, but WOA does some voodoo magic on the barrels because they shoot great and they don't copper foul.

I just broke in a WOA Service Rifle barrel during Thanksgiving Day weekend using the same 10 round break-in I usually use. First 2 individual rounds had a bit of copper fouling, but then the next 2 individuals rounds the amount of copper tapered off considerably, and the 2 3-shot intervals had minimal. I had the same experience with my first WOA barrel (complete WOA SR upper).

WOA advertises that they use their own branded White Oak Armament barrels (probably the Wilson Blanks), PacNor SuperMatch and Krieger barrels

[ocabj]

Correct. According to the WOP FAQ, they use Wilson blanks, at least for the WOA Service Rifle barrels, that are cut by by Compass Lake. The in-house barrels used for the WOP uppers are Pac-Nor (standard) or optional Kreiger.

Never had a Krieger barreled AR. Here's a question for you: I have the WOA 18in barrel on one AR, and had a 20in douglas on another from fulton armory. Both have 1 in 8 barrels. Both of these barrels didn't like the 68's or 75 BTHP's from Hornady, no matter the load. Always around 1.5 MOA. But the 77 SMK's shot pretty well with about any load. I've had good luck with the hornady's in my boltguns, but haven't been able to get them to shoot in the AR's well. Would a better quality barrel, be it Pacnor or Krieger, be "better" with a wider range of bullets? I know its a very general question as all barrels are different, but what has your experience been?

[ocabj]

I honestly can't say what the issue is. I've had no issues with the 75gr Hornady BTHP. All I do is stick 24.0gr of Varget or RL15 in a CCI primed LC case, top it off with the Hornady 75, and go.

If you've already tried varied powder charge weights, then I guess it's just the simple fact that your barrels just don't like the Hornady bullets...

What powders have you tried and with what primers?

I've contemplated actually switching to the 75gr Hornady BTHP for the short line because according to Hornady, the BC is better than both the Sierra and Nosler 77gr BTHPs.

The Sierra heavy 22cals are very jump tolerant, but you figure the Hornady 75 BTHP has to be jump tolerant, too, considering it was most likely designed with service rifle shooters in mind. You could try seating the Hornady out just off the lands to see if it improves, even if it exceeds magazine length, just to eliminate that as a factor.

Yeah, my goal is accuracy from mag length ammo. I've tried all kinds of ball powder (748, 2230-c, H335) and 4064. I have not tried Varget...yet. I've tried Fed and Win primers with most of those powders as well. I'm not done, I just have more development to do. I just figured it may be a picky barrel. From what I've seen and read, thats not common from WOA.

I bet Varget will get those Hornady's shooting good.

+1

Varget or RL15, and either the CCI, Rem 7.5, or Russian primers. Has worked in every service rifle upper I've had.

BTW Robert, for a guy on dis, you sure spend a lot on guns
