Do research for reloading the .303
Fireform your cases, then only neck size.
Use, "starting to mid range" loads only, (if you have a sloppy chamber as most LE's do.)
You will get good case life doing this.[/QUOTE]
You can't go wrong following the advice above. My first experience with reloading for the .303 was a bit scary. With once fired Federal brass, I was getting complete case head separations in my LE No4 Mk2. I put up a post here on CGN and received many helpful replies. I thought I had a headspace problem and was looking for a #3 bolt head to cure the issue. Headspace checked out OK. Turns out that full length re-sizing was the culprit. Even with once fired brass from commercially available factory ammo, full length re-sizing can work the brass enough to weaken it just above the web.
To the above advice I would add only one more tip.
Whether you start with new brass or with factory loaded ammo, only use the brass fired by a specific rifle as re-loads in that same rifle.
