Krauger action wto switchlug build - 3 caliber ackley improved need advice. 510 whisper 338 lapua 300 rum.

[Archimedes]

Hey, so I’m putting together a rifle
Krauger vpr sst 338 long action receiver nitrided
3 barrels from McGowan precision
1 338 lapua 40 degree ackley improved 32 inch bull
1 300 rum ackley improved 32 inch bull, possibly extended cut chamber for 3.740 coal loads
1 510 whisper 10 bull
Xlr atom chassis, built as a pistol but can be converted to rifle. Pistol config is for the 510 whisper using a brace.
3.850 CIP magazines
West Texas ordnance switchlug system

Couple of questions
Can I modify the chassis to accept the switch lug system and where can I get it done in quality manner that’s not pricey.
Will wto take in McGowan barrels to do this build?
How likely am I to experience feeding issues with all 3 calibers?
Trigger recommendation?
Can I buy an extra bolt for the 300 rum from Krauger or perhaps some other company and how much will that run me?

Any recommendations overall on the feasibility of this build? Different parts recommendations or reputable gunsmiths? Am I missing anything here?
I’m selling my Remington sendero ii 300 rum to partially fund this, I figure the cheapest way for me to shoot all 3 calibers and do it easily is to go this route with the switchlug.
Main concerns are budgetary in nature.
Main point is to have a rifle system capable of shooting all 3 calibers accurately and to switch between the calibers easily, ergo switchlug.
Mandatory to be able to build it as a pistol first so I can have a 10 inch barrel and use a brace while also being able to use a rifle stock with the rifle barrels.

sounds like too much work gong from pistol to rifle then back again

Build a separate rifle and a separate pistol and SBR the pistol

I'd be willing to bet that by trying to do all of this with one rifle system, you're going to run into a significant amount of problems. Shootability, feeding problems, generalized frustration of all the work required to switch everything over to a new caliber, and a significant amount of wasted ammo zeroing the rifle every time you switch things over. Given the fact that these aren't common or cheap cartridges to buy ammo or components for, that last one is going to suck.

Coming from a guy who went down this road in a couple different cases. the quick swap shit ain't all it's cracked up to be. By the time you buy all the necessary components and deal with all the shortcomings from compromises made in the name of universality, you're time and money ahead outfitting multiple rifles for different use cases. It's really easy to make enough compromises that the rifle isn't really good at anything anymore.

At a minimum, I would build the .510 whisper into it's own rig and maybe talk to Kauger and WTO about the other two, but I would still consider just building the 338 and keeping the sendero for 300 RUM assuming you like the rifle.

The Kauger action has a hood over the top and side of the recoil lug.
Did you have yours machined off?

If not, the WTO lug won't work

In reference to your extra bolt question, you can buy extra bolt heads. No need for an extra complete bolt assembly.

According to wto the moa shit you’d experience is .5 and I would mostly be shooting 338 lapua or 300 rum. I feel like it’s such a minimal poa shift that I can re zero fairly easily, I do reload my own ammo as well so it’s not as pricey as factory ammo.

Also this way I’m able to retain my 300 rum, if I can sell the sendero, so it’s just another cost saving measure. Plus I do want a thicker longer barrel with a different chamber.

If I were to keep the sendero and use a pacific tool and gauge receiver for the 510 and 338 I could have the expense be mostly the same, you’re right.

They gave the suggestion of the krauger, so I assume it will work and that they will modify the receiver in someway.
My main concern is modifying the chassis.
