[QUOTE="charlie 7, post: 1386014, member: 66237"] Winkfish I’ve read the whole thread and I am convinced that the engineers at Remington did a very good job designing your gun. I don’t think that the fouling of the barrel is the culprit, I think the whole event took place while the projectile was still in the chamber as once the bullet travels down the bore pressure drops dramatically. The unusual location of the case separation stretch mark as seen in post #50 points to the lubricant in the chamber or on the case. Good gun design !!! as the lugs sustained the whole brunt of the charge with a lubricated (well, half of it) case in the chamber. I suspect that the case was loaded for the 190gr projectile and when 230gr was seated to the same COL, the projectile reduced further the powder space sending the pressure higher still. There is 180 thou difference in length between those two projectiles.
