I am getting this expansion in the case just above the web in my 22-250. Is this considered normal for this round or is my chamber possibly out of whack? The expansion is even around the circumference of the case, and I don't see a "bad spot" so to speak. I can see this leading to eventual head separation after a few re-loads. It occurs with the factory ammo, and with my "mild" hand loads of only 36.5 grs. of H380. It is expanding about .002" ... just enough to force me to re-size the whole case every re-load, as opposed to just re-sizing the neck. This is gonna kill me on the economy side of bass savings. Is there any way I can spec out my chamber and compare it to other chambers (yours), in this caliber for reference. I don't want to send it in if it is within specs and they won't replace/fix it.
