to continue..why do this ?
basically a new cartridge
the numbers are aprox 75 fps FASTER than predicted by software,
while having no indications of pressure issues, easy bolt lift, no ejector mark on the case head, primer still has a rounded edge.
i can now do some real load development, off a front rest, maybe with some distance 200/300 yards.
two things to note
1) THE BEGINING LOAD 2823 is super sonic past 2000 yards at my match elevation;
2) ignoring the first cold bore shot, sighters 2.3 and shot 1 of the string
had an average of 2822, and an sd of 1.5
( yes shot 1 is 2823..not 2828..typo)
