Sorry about the long thread. can't help it, it's my nature. So here's another one. I'm assuming you are referring to the 03A3. Not sure if it is a A1 or an A3 and more than likely you plan on keeping it chambered in 30-06. Is it mill. grade or modified? I have a 03A3 model of 1903 that was sported and weaver scoped. It was my dads favorite hunting rifle and we re barreled with a unused surplus 4 land/groove tube. Brings back many great hunts ant range sessions with my dad. As far as a hunting rifle it turned out sub MOA at 100 yards with good hand loads and loved 165gr sierras. Have to say it is my most cherished of my collection. Because of the age of these actions most will tell you to be concerned about the strength of the steel in the actions. Rock Island, Springfield and Remington all built these actions for our military. The military proofed them to 125,000 psi plus. From my notes the Remington produced actions where much stronger and used a better mix of alloys in the steel. Rocks and Springfields where known to have brittle steel and could fail with high pressure loads and rechambering for larger magnum calibers loaded to maximum pressures. Research for yourself always but the A1 was Remington and stamped 1903 the A3 was of the other two. Any numbers under 3348086 should be an A1. For barrels other than mill spec. ER Shaw, Hart and Shilen make good barrels but not sure if they supply barrels that directly thread to 03 actions. If you have the duckets to spend and don't mind waiting check out ABS carbon barrels. Nothing sweeter than a old meets new carbon barreled 03 on a custom bed with tactical glass. I'd use a 26" tube to squeeze every bit out of a 06 with a 1 and 10 twist. Carbon barrels reduce weight and increase felt recoil but shouldn't be a problem with an 06. They are more ridged with less harmonics and dissipate heat much better and that means no wondering shots on a string. A good smith can square the bolt face, receiver and lugs mate a new barrel and set head space and produce an accurate rig. If this gets you drooling thanks for letting me help you spend your money. Enjoy your 03 they are great guns.
