Using Factory Actions for Builds...?'s...

ARC Nucleus is looking pretty nice.

Half the fun of a new rifle is the research of and deciding which parts to use?
There are choices for everything!
Then shooting it confirms if you made good choices...Or not?

Yes, I understand the upside to using Custom actions when building rifles.

But when using a Factory action, whether a Remington or Savage, what are the things to pay attention to?

Various sites sell "Trued 700 Actions".
Is there a big comparison between a factory 700 and a Trued Action?

I have a factory Sendero 300 RUM that I'm thinking about rebareling with a Bartlien Barrel

I have a 338 Edge built on a Trued 700 action that I bought used from a member on this site.
That gun is accurate as hell.

Just use the factory Sendero action, or buy a Trued 700 action?

Thanks

If you are going to rebarrel your M700 Sendero, then you will want to have the action 'trued/blueprinted/squared up'. You may not achieve the best accuracy from your rig if the action is not trued. My only concern with buying a 'trued action' is that 'trued action' may mean one thing to the site you would be buying the action from and may mean something different to the gunsmith building your rifle. I would check with your gunsmith first about the 'trued action' and get his input.
As far as M700 actions go, you will hear a lot of negative about them, but they are very good actions to build a rifle with, as long as you get them trued up. You have one your self.

Good Luck with your decision

Ya, the 338 Edge I bought used that's built on a Trued 700 action is a laser!

Yep, lot of innovation through that action ... https://www.americanrifle.com/produ...n-26-with-deposit-425-non-refundable-deposit/

Yep, and that's exactly what I did ... acquired all the components (action, trigger, barrel, stock) and have my reputable gunsmith build it.

Use the action you have. Rifle actions machined on CNC equipment should be very accurate. Sure you can lap lugs etc and get full contact, as there are two mating interfaces. The action is one piece. I have a really hard time believing that the front face of your remington and the threads on the inside of the receiver are anything but square. There is no reason for the action to come out of the chuck when machining the threads and the front of the receiver. Likelihood of them being off axis is minimal.

Your attention to detail with handloading will pay bigger dividends than getting a "trued action". Have rebarreled a .35 whelen and 300 win mag rifle and all have shot 0.5-0.9 minute 5 shot groups consistently, and dozens of 3 shot groups in the 0.1-0.3 range. Some I found the load it liked quicker than others, but both shoot. Working on a 26 nosler right now. Two of the rifles were savage and one was a remington. Both use the barrel nut system.

Two most accurate rifles i own are two factory remington 700 sps tacticals in 308 and 6.5 creedmoor. Neither of them are "trued". I'm sure that people will disagree with my assessment and that's fine. Do whatever toots your horn. I just haven't seen factory actions causing any issues. Own a TC Venture .243, Weatherby vanguard 2 .270 win, REMINGTON 710 (which overall is a crappy gun, but with bedding handloads and trigger work it shoots), 2 remington 700s, plus the two that I have rebarreled and all shoot it just took awhile to find the load the gun likes. Good luck.

I picked up my Stiller Predator LA Magnum from Redhawk Rifles when they had a 10% off sale a few months back. Ended up getting it for $900 including the transfer fee. Gunwerks has a new action available for $850, however I have no experience with it.

If it already shoots great, a truing job is not necessarily needed, especially if you ever wanted to make a remage system out of it. Don't buy a new action unless you want to leave your Sendero how it is, just use that action. Most people will have them trued when rebarreled, however if you don't want to spend the extra $100-250 (depending on smith) for a truing job, you don't have to, and the rifle should shoot at least AS GOOD as it did with you r factory Remington barrel. But if you have it trued (if done properly) you know if there is any issues it is not from the action.

I beg to differ... EVERY action, including aftermarket custom actions can benefit from truing. Factory actions need complete "blueprinting", but customs still need to have the face checked, and possibly trued to ensure it's as close to square as possible. They're still mass-produced actions, just built to much tighter tolerances than most factory rifle actions.

I checked the Gunwerks action, it has a "less common barrel thread tenon specification"
Why?
So you can't use a standard Remage barrel?

If your goal is to have the ability to use a barrel nut, then BHA is an excellent choice.

If you have your factory 700 Sendero action blueprinted for your build, it will shoot just fine. But if you want a top-notch custom action, look into the Curtis Axiom action or Defiance Deviant.

You should still be able to run a remage setup if you want. You will just have to let the barrel maker know the thread pitch of your action.

I have used pierce engineering, defiance deviant, sako 75 and tikka actions for builds. Pierce is nice because they are in your price range and come cerakoted to the color you want. Their gunsmithing prices are very reasonable.

I would say whatever you do get ALL the parts first. That's what I have seen as the issue in a lot of builds is utilizing the gunsmithing for parts and it taking way too long.

If you are going with a custom action and want the performance of a 300 RUM I would seriously consider the 300 Norma Magnum now that lapua is making brass for it.
