Picked up a box of the new lot number 314 and some new 6.5 brass.The loaded ammo shot .6 to .7 and was loaded with 44.7 grains of some kind of powder seated at 2.815.The new boxes of brass I got ranged in weight from 146.2 to 153.1.I shot this out of my son's 12LRP that I just got back from savage for the second time to get the throat fixed.At least now I can load a 140 amax out to 2.830 instead of 2.740.What kind of BS is this with brass weight?
