These are pre-fits from Lothar-Walther in Georgia (USA).
I have the 28" .260 with the Savage Varmint Contour and used it in 1000yd F Class for several years. Due to careful attention to bore preservation (no hot loads, and only using it for actual competition shooting) I conservatively estimate it still has another 1000 rounds of life in it; the LW-50 Stainless Steel is some pretty tough barrel material.
It can also give some gunsmiths issues when machining it, so an L-W factory pre-fit is the better way to get one. The list of chamberings shown, minus the .223, should work with the .308 bolt face diameter. Note that the barrels specs shown are not the only ones that are available, and that while mine conforms to the spec shown, it was ordered and produced years before this pre-fit program was inaugurated.
If you want something similar but
different, give them a call. I did and I got a damned
fine barrel (two of them, actually).
I think that the resale value of a rifle with an L-W barrel would need no excuses. These are the Cadillacs of rifle barrels, and come from the world's
largest supplier of OEM and replacement barrels.
The Savage Accu-Trigger is quite good for a factory trigger, and others (like Mossberg) are lately beginning to emulate Savage features, like the trigger and barrel nut. Their manufacturing precision is good enough that truing may not be as effective on them as with other brands, and the floating bolt head eradicates most issues involving bolt lug contact. Also, while the Savage and the Mossberg share barrel swapping capabilities, the barrels are not interchangeable; the case protrusion spec is different.
