RE: Used brass
You need to be careful about buying used brass. Sometimes stuff that is advertised as once-fired can turn out to be pretty well used up. For all the more you are looking to buy, you'd be better off going with new.
I pick up a lot of 30-06 brass at the range. pretty easy to resize to 25-06. You could probably do the same with 308 for your 243
I found that 270 Win works even better ,not so thick in the neck . But as far as 308 Win to 243 Win for 50 rounds it isn't worth the effort in my opinion we tried it but it was to much labor for little gain .
