I've got a New Haven late 90's standard long action and a Brown stock "sitting around." Was gonna build another Whelen but I dunno. Haven't been supporting the economy enough.

So: apologies for the dumb question.

Aside from getting the bolt face opened up (by whomever does the barrel install), swapping out the extractor for a magnum extractor (which I have), and putting a 458 follower and mag box in, can I build a 458 on this thing? Are the factory 458 actions machined any differently from the standard long actions?

Might be the berries to have a stainless 458 for my occasional Alaska jaunts. Even if I killed my last caribou with a 7-08...

And for a final maybe dumb question, I sort of prefer 24" barrels to shorter ones. But is a 24" 458 gaining much over a 22"

Thanks in advance.

Edit: Just realized I have a 375 HH mag box/ejector/bolt stop off another project. Maybe a 458 with a longer box?
