Just to reiterate some of the previous posts, it is very common with my Lee case trimming equipment to have to shave lots of brass from the .303 cases that I pick up off the range. I currently full-length resize any brass that I purchase or come across at the range, then separate the cases based upon the rifle that I've fired them from and have used my Lee Loader to only neck size the brass (of course a Collet Die would do the same and slightly faster).
I entered into reloading a year ago and have thus far loaded both cast and jacketed bullets for a variety of calibres.
Thus far I've fired off my milsurps with reloaded .303, 7.5x55, 8x56R, and 8x57JS. I have had some decent success with my .22 Hornet reloads as well.
I still have to try out my 6.5x55 and .308 reloads, time permitting, and have loaded up 9.3x57 and 9.3x62 for Swedish Mausers that I've purchased from Tradeex.
While the number of calibres, experimenting with different powders and the purchasing of lead casting equipment might have lead to a high cost per shot based upon my expenditures thusfar, over the longer term this looks to be the only way to feasably shoot all of these rifles. I am very glad that my entrance into reloading has corresponded with the availability of 9.3x57 and 9.3x62 rifles. Nevertheless, I would also recommend it to the person shooting only a few different calibres, and would think that such a shooter will be better able to focus on producing the best loads for each of his guns.
Cheers,
Frank
