What big bore caliber could/would you build on it? I have reservations about building a modern magnum (65,000psi)cartridge rifle on a 03A3 action.

Would it accommodate a 404J or 458WM? What problems are there in opening up the bold face and magazine box and rails? Kudude

Here was my solution to this question. It is a great set up.

When I was a kid one of the first gun magazine articles I ever read (other than those found in my Grandfather's Outdoor Life) was the story of a fella who put together a 16 inch, 6-15/16 pound 1903A3 in 458 Winchester Magnum.

Was the article an obituary?

Depends on the hassle you want to go through. If you don't want to open up the bolt face ... go to a 30-06, 338-06, 35 Whelen, or 9,3x62.

If you're willing to open up the bolt face then .308 Normal Mag, .338 WM, or .358 Norma Mag come to mind.

I have a Springfield as you describe in .308 Norma Mag and love it.

As I already have a .338 Win Mag, a 9,3x62, two .375 H&Hs, a .416 Rigby already and a .458 AR in progress ... I'd probably do a 30-06 which (believe it or not) I don't have.

It would have to be a 35 Whelen, with a 10" twist.

kudude, might consider Rugers new offering in 07-beltless. boltface, perhaps rail work, trigger, stock, some brass, bulets and shoot! sounds good.

I have a P-17 waiting to get turned into a big bore. So if I had an '03/A3 I think I would turn it into something like a .338/06. I like Rich's idea of a .35 Whelen too.

MJ,
I saw that lovely thing earlier, and gave it some serious thought particularly since I'd have a reason to visit the area. My son and his family live in New Braunfelds.

Potential problems: mine is a 03A3, so the rear bridge isn't quite the same; however, because I have old eyes, I've give some thought to pulling the scope mount and going back to a peep. Kudude

I did one in 416AR recently.. have done,

I'd build a 400 Whelen (Improved) on the action.

I just used that caliber in Tazania, and liked it a lot.

Other than a new barrel, it shouldn't require any other work.
