If you're worried about wearing out an Enfield, take heart. First, it's a very mild cartridge (I just love the .303), and it's really hard to wear out a barrel with the .303.
But the really good news is, it's an extremely common military rifle, and if you keep your nose to the grindstone, you should have no problem at all locating a new condition military barrel. They're easy as pie to re-barrel and 99% of all Enfields are headspaced on a "Field" gauge.
Just keep shooting, and shooting and shooting. Nose around from time to time at different websites and keep your eyes open for a new barrel. Should be able to get one that's downright reasonable.
As for .303 bullets. the Hornady 150 grain SP is an excellent medium to long range deer bullet. For large game, the Woodleigh 215 grain SP is outstanding.
Enjoy your Enfield...They're just too cool.
