I cant seem to get consistance in the ammo pressure wise, the accuracy is fine but!
i have done the load development and thought i had it sorted at 44gr N150 behind a 70gr blitzking
I fired 20 shots today and probably 12 were fine, 8 have soot marks down the neck and onto the body,5 had small marks on the head from the ejector 2 had blown the primer out alltogether and 1 has blown the primer and had bad marks on the head from both sides of the ejector mechanism
I measure each powder charge out to within less than a 10th of a grain
Someone has suggested that the brass may be at fault, I aquired it with the rifle but do not know its history
