Contemplating a new rifle build. I currently have 3 Savages with pre-fits, which all shoot pretty good (sub-MOA with 95% confidence long term, or for the statistically challenged..."half MOA all day long if I do my part" ;) ).

They're all three pretty good hunting rifles, and nearly identical in weight, form, and function, only differing in pill size (264 WM, 7mm RM, and 300 Win Mag). Problem is, they're all a bit heavy (11 lbs), a bit crude, and not quite as accurate as I'd like...

So...New build Criteria...

1) ≤10 lbs outfitted, but a stout enough barrel to shoot a few rounds in a few minutes without setting fire to anything.

2) Capable of chucking 200 ± 25 grain, 0.69 ± 0.2 B.C bullet at 2940 ± 60 fps into less than 0.8 MOA for 10 shot groups at 200 yds in ideal conditions.

3) Adjustable comb and LOP stock. Not necessarily on the fly adjustable, but user adjustable with some simple tools and effort.

4) $3100 ± $250 OTD, not including optics.

5) Build it myself (e.g. prefit bbl, drop in stock).

So far, I'm looking at...

1) Long action ARC Nucleus ($1000) or Archimedes ($1400). Is the Archimedes worth $400 more?

2) 7mm Rem Mag or 300 Win with long throat for heavies (have the stuff and experience to load these already, but MIGHT be convinced to go with something else). Thoughts on "special" reamers, which won't break the bank to utilize?

3) 45-50 oz barrel, 26". Carbon ($850) or fluted 416R ($600), medium-heavy contour, Savage style nut. Not sure who to go with here.

4) XLR Element 3.0 Mg chassis and XLR AR TR-2 Buttstock ($800)

5) Trigger Tech Primary trigger (I won't run anything under ~2 lbs, so no need for a real fancy unit, but perhaps the "Special" is worth $40 more?).

6) MBM Super Baby Beast or Lil Beast 3 or 4 port brake ($100)

That's about it. Am I wrong to think I could bolt that all together easily enough myself? I've installed 3 Savage prefits, and pulled apart a couple of Marlin X7s, so I have the necessary tools/equipment for the barrel. I'm fairly handy and have access to some simple machining tools (old lathe, mill, etc), but couldn't do any sort of complex work.

Thoughts?
 
I would go to an action that you can buy shouldered pre-fits for instead of running a barrel nut. I have a terminus Zeus, excellent action and easy to spin on a barrel for it yourself.

I prefer a stock over a chassis especially since most are fairly heavy, although that does give you stability
 
Some suggestions to help in the accuracy / repeatability dept:
  • Face off the action (you probably already have)
  • Good, precision ground recoil lug
  • Use a square shoulder instead of the nut.
  • Have your bolt face squared, and the bolt timed.
  • Tune your firing pin - new spring, bolt head bushing, etc.
Stock depends on the barrel selection, length and weight. If you're looking at a 48 oz'er, I'd go to a fluted heavy sporter. I much prefer my rifles to balance like a good knife, with the balance point being somewhere around the recoil lug.
 
I would suggest looking into one of the lighter actions. Maybe a Lone Peak or a Defiance antix. I would also suggest a shouldered setup for a nice action like this. I do lots of savages and love the barrel nut setup but on a custom I would do a shouldered. Putting on the barrel will be a snap.

Any reason for the shouldered prefit suggestions, other than looks? I've done some googling, and everything I saw indicates there's no discernible difference in accuracy. I'm not sure yet where I'd source a barrel, but it seems a shouldered barrel will limit my options more than a nut style, as the shoulder will be somewhat unique to a particular action family, while virtually every manufacturer makes a Savage prefit.

The XLR Element MG setup is only about 34 oz with grip/stock installed, so I think it sits right in there with "regular lightweight" stocks in it's price range. I never weighed one of my Accustocks, but for reference, an OEM Marlin X7, short action, tupperware stock comes in at 28.5 oz.

Regarding the Terminus, Lone Peak, and Defiance receiver options, they are pretty spendy, with the lightweight models being even a bit higher (particularly in Ti) for only a 6-8 oz weight savings.

I wasn't clear in the OP, but I'm actually not trying to shave every ounce off. The 10lb weight limit is "ideal". Much lighter, and the recoil will be more than I want. This will be a hunting rifle, but not for steep back country stuff. It will also be a range rifle for fun steel plinking. My reference is my 11 lb Savage 300WM with a brake, which is no problem for even inexperienced shooters. That said, if I go with 7mm, I could stand to lose another 6 or 8 ounces for sure, and of course, less weight in one area means I can add weight in another (scope, barrel, gadgets, etc).

Just wanna try and stay in the lane on my budget, as I know how these things can creep...:rolleyes: I do want to get the best bang for the buck though, so I'm certainly open to other options.
 
Shouldered are nice because you kick the go-no go gauge to the curb. That obviously saves money. As for getting a barrel you can buy off the shelf for a shouldered as well or have a gunsmith make it for you.
Maybe look at a Bighorn origin if you aren't worried as much about weight on the action. Plus all your Savage small shank barrels will fit. It's also a bit cheaper at $850. You can also easily swap the bolt face between mag or standard if you decide to change it up. Just a thought for you.
 
I just did a 280ai on a Lone Peak nitride stainless Razor action, a #19 contour stainless Bartlein barrel (25"), Grayboe Terrain Stock (2 lb) and DBM, Hawkins UL Tactical Rings and a LRTS scope (heavy glass) and it came in well under 10 lbs. Rifle felt really nice and lively before putting the tank of a scope on it... but this one is for dialing, a necessary evil.
The barrel is the Remington Magnum sporter contour, which is about an ideal contour for a long range hunting rifle IMO. Also, since the Razor is a timed action, we did a shoulder pre-fit on the barrel to enable non-gunsmith barrel changes.
About $3400 including optic.
 
As you stated in the OP, one of your battles is heat. Hence, as heavy a barrel as possible.
Shouldered, because:
  • Much easier to order an unchambered blank
  • One of your desired outcomes is to have a predictably accurate rifle, that your current pre-fits are "not as accurate as you like."
    As @Alex Wheeler pointed out, a shouldered barrel is the best way to "point" your barrel. I was only vaguely aware of that until recent discussions with the gunsmith turning two blanks of mine, where not only is the bore often "not perfectly centered", but in the straightening of the barrel, there is an inevitable arc that you have to set up for. In a shouldered prefit, I'd hazard to say that neither of these will be accounted for.
  • IIRC you are in eastern WA (haven't forgotten I owe you some 357 Mag brass... :oops:). I should be receiving my barrels at the end of this week. I'll ask him if he's interested in more work.
Edit to add:
Thoughts on "special" reamers, which won't break the bank to utilize?
You can rent.
To give you an idea, the smith turning my 6mm Rem AI calls this morning and asks, "what bullet are you planning on shooting in this ?" I answer, "Berger 105's". He immediately knew how much throat to give me to properly seat those bullets. IMO, that knowledge is worth every dollar spent.

Here is what I use. 9.5 lbs. Folding stock is not a must for most but it is for me. It would be close to 9lbs without. The modified MDT chassis sits at 3lbs with the folder and 2.5 without. MPA and XLR make 2.5 lb chassis with a folder out of the box though. Take the 9 oz can off and you're at 8.5 lbs.

I'd choose a short action set up like a 7 SS or 7 Saum perhaps since you want heavier bullets.

MDT Chassis
Bighorn TL3
TT diamond
Proof barrel. I have an xcaliber in a 18" that is replacing this 22" at some point>
TBCA ultra 7. Have a dominus on the way. It is a little lighter and about 1" shorter.

I was a Jewel snob for decades and they deserve their reputation. Now I put Special Primary triggers on everything. I like the single stage and straight shoe. Hard to beat.

Man that's a good lookin rig. Thanks for the pic
 
My 25-284 came in at 9.5 lbs scoped. EH1,700LA, Helix6 CF barrel, 3 port brake, trigger tech, Remington BDL BM, March 2.5-25x52. Balances very nice. Not adjustable comb so not sure how much weight that would add.
