Is it worth getting a Wilson cartridge gauge for .303BR?

I too have suffered frustration trying to reload .303 British. If you full length resize so the ammo will fit all your guns you will have to trim the brass every time. By the third loading you will have a significant number of case separations. The only up side is that owing to the significant taper the broken section of the case will come out stuck on the round you just extracted because the bolt wouldn't quite close.

If you neck size to increase case life you have to dedicate brass to each gun you shoot. Here is one time the Lee collet dies seem to have it over other methods of neck sizing only in there is less stretching and subsequent trimming.

Nobody makes a flat based 174 grain spitzer. While Horndy and Sierra make some lovely boattail spitzers many MILSURP rifles have seen enough Cordite that they sling them more than they shoot them. On the other hand, out of a new unfired Vickers barrel, the Hornady bullets atop a moderate charge of Reloader 15 the Hornady bullets would pass the "punch firing test" of a 50 round burst within a 2 foot by 2 foot square at 500 yards required before firing over the heads of friendly troops.

Sure wish some of the WCC 81 or the Greek HXP stamped stuff was still around.
