Re: new brass vs. used
CST, from past experience with .243 Win., fired from a Sako varmint weight barrel, new brass from Norma (i used Norma ammo & brass exclusively in that rifle) shot very similar to a factory loaded round, where accuracy is being tested against a case that was once fired and reloaded was found to be very little difference, when i gave that rifle to my Son, i also gave him all my collected data, but to the best of my recollection the difference between new brass and once fired was of minor significance, on paper, the groups were all within 1/2" of each other, (meaning new brass vs once fired, in fact new brass vs 10X fired brass) i was still popping Commiefornia ground squirrels at ranges of 50 to 350 yds. the majority were in the 150 to 200 yds.
