Another thing to be aware of when loading for old .303 for Enfields is a problem with the head space of the gun. They are notorious for that. Case ruptures around the base/rim could be indicative of that. This is due to the bolt locking lug design. The locking lugs are located in the rear of the bolt, not in the front, like most other rifles of the class. In older rifles, repeated firing can actually compress the bolt body minutely or stretch the action enough to cause excessive head space. This is a very dangerous condition, and can and will cause catastrophic case failure around the base, venting the hot gas into the shooter's face and and/or blowing the action up.

If you have another case rupture, have it checked by a qualified gunsmith, if not before. The problem can be easily fixed usually, by head space adjustment. However, not after you blow it up.

if you are reloading, put a small oring on the rim for fireforming, then neck size only. The brits made chambers sloppy to allow off spec/dirty ammo to work in war time. This is not conducive to brass life however.

It already is!

Ive found the best thing is to stay consistent, if you do something do it to all of them... (Except screw up, of course!)

The SMLE Enfield is famous for head space failure. They have issue bolt heads in type 1,2,3 to change out the bolt heads as they wear. As I recall the type 3 heads are in short supply. This rifle has a typical Enfield head space problem. The new ammo will fire OK for awhile longer. The reloads will be a problem.
