Thread: Lapua 6.5 PRC Brass - Split Necks

I think what is weird is how the crack is shaped....and the other one forming is shapped same but in mirror...its a straight split but has two smaller splits on each end slightly further around the neck so 1;00 and 1;05 if you will..... so its not the same burr/dent/ridge on something doing the damage or all would be the same orientation.... please take photo of a few others together so can compare them....is it optical illusion or are edges of crack peened inwards??? like neck has come out onto a bit of crap in chamber...something like a tiny bit of wire or burr of case..which actuall WOULD explain the same shape of cracks,and maybe its flipped over in chamber neck at some point thus the mirrored dent???

All of this brass has been fired in the same rifle but only some of it has cracked. Chamber is spotless, im pretty careful with my cleaning. Will put a picture up of some other cases. - Just tried to take some but its hard to get a good picture with my phone. Cracks dont all look the same "shape" theyre all vertical and in various stages from just beginning to blown all the way through. No crack is the same as another & each case has 4-5 different cracks total around the whole circumference of the neck, some worse than others.
