Enfield Tanker project NOW 95% done

...

I have a drawer full of various heavy 308 barrels off target rifles and such. One of them is a heavy 308 Win barrel off a Winchester M70 that got blown up with a case of pistol powder.

I have thousands of 308 bullets laying around, but few 312 bullets, so I used the 308 barrel to make my own tanker. I left the barrel heavy to within an inch of the tip of the stock. The last five inches are turned down to Lee Enfield diameter, complete with new bayonet lugs.

The chamber was cut with a 303 Brit profile, with a tighter neck since it shoots 308 bullets. I was hoping this would prevent loading real 303 ammo, but the neck is not quite tight enough to do that.

By using the 303 Brit case, the magazine, extractor and ejector all work without modification.

A heavy-barreled .308-03, or would that be .303-08?
 
I have now taken my lead from names like 7-08; 6.6-06 and decided to call it a 30-303. The labels on the ammo boxes are now written that way.

Was tempted to call it a 30-03, but that name was taken.
 
303

Regarding the name of 303/308 combo, I believe that Steve Regwell of 303british.com once wrote about 308 barrels being subsituted fof 311 barrels and the combo was called the 308 British. Just more info. Great thread.
