Well I am not having a very good day today at all. /ubbthreads/images/graemlins/frown.gif I loaded up the 6mm 110gr Wildcat bullets Kirby was nice enough to send me and went out in the back yard for some load testing. I started at 50.5 grains of R-22 and I have shot up to 52.5 with the 105 A-max without any trouble. I shot the first group and they shot about 2inches at 300 yards. I had no sticky bolt no pressure sign that I could see so I grabbed the second group which was 51.o grains and fired a shot. Well next thing I know the firing ping is sticking out the back of the bolt and I have some nice hot powder on my cheek and hands. /ubbthreads/images/graemlins/mad.gif I had to tap the bolt open with a rubber hammer and I was able to get the pin out and it looked fine the bolt also looks fine but I am going to have to take the bolt in to my smith because I cannot get the case out of the bolt face. This rifle is my baby and I hope to GOD I did not ruin it. /ubbthreads/images/graemlins/frown.gif I have never had this happen before in 15 years of reloading. I do not know what happend? No sticky bolt, no ejector marks then .5 grains more and the gun comes apart and the powder LOT is the same? I know these 110 bullets have more bearing surface then anything I have shot but would .5 grains more of powder would cause that much of a pressure spike? I am also going to pull the bullets and weigh the powder charge on another scale to make sure my scale is accurate. Can one of the smiths here tell me if I weakend the action and the bolt? I was using Lapua brass and the case did not come apart thank God.
