Until the other day, I was under the impression that any Savage Long Action could handle a .338 Lapua chambering. But... I saw a comment the other day, and I'm now not so certain of this.

Are factory Savage .338 Lapuas made with a receiver unique to handle its overall length?

Or could I just buy a stainless Long Action from the 110 family, and be certain I could order a Lapua chambered barrel, the correct bolt head, and be confident it would be safe and feed reliably from a box mag?

I ask because of a comment comparing the Lapua to the .338 Edge... but I may be missunderstanding the situation here.
