I have done some load development with 1 and 2 fired brass and assume that 2nd fired brass will give better results than 1 time fired and much better than unfired new brass. The problem I have is that I don't have enough once fired brass to do the load testing I want to do.
I have 200 unfired ww cases (223 ww), that I want to use but don't want to load and fire uselessly.
My question is : is load development with new cases significantly different from the same, using 2x fired cases? I body resize after 2x fireing and neck size with collet die for every loading.
