Took the savage 10 fcp-sr out again. This time i put my nightforce nxs f1 3.5-15 reticle is the np-rf1 .25moa clicks moa reticle: winds were gusting right to left and left to right swirling about due to the high berms making it very swirly. temp 51 degrees humidity 69% ammo was hornady 168grain amax over 44.3 grains of RE15 loaded out to 2.809 OAL using cci primers. all shots were 300 yards. still using the weak firing pin spring making ignition of the primers iffy at best. i never was able to get 10 in a row to go off. first group 6 shots 4 fail to fire. 2.5" spread approximate. second group 8 shots 2 fail to fire if it wasnt for one flier totally me yanking the trigger this would also be a 2.5" spread the good news is that after an annoying morning with the light strikes i stopped by my LGS and he had the warranty replacement spring!! i just got done replacing the bad one and its a bear to get the end nut off the bolt. had to wrap the bolt in a towel and place in a vice to get the nut off. savage used a small bit of red loctite on the edge of the nut. im grateful they didnt put that crap on the threads!! just a minor spot of it took most of my strength to break it loose!! spring swap done bolt reassembled so i pulled a few bullets and dumped the powder back in the re15 can. with the new heavier spring all the primers went off. i expect the next range session will not have misfires and accuracy should improve with more vigorous consistant primer ignition.
