I am reloading a 22-250 IMR4895 with 34.3 grains of powder. 55 grain soft points. Full length resizing. Cases trimmed. About every 10th round the case blows in two right where the thick part and the thinner walls of the case join. About one half inch from the base of the case. The rifle is a Huskavarna that I have had about thirty years. I always thought that I may have loaded them to heavy, but I have been checking them twice with a powder scale and also with a Lee Dipper.
Can any of you help me with this problem? I would like your input as to what is going on. Thanks
