.243WSSM factory Winchester ammo, 100 gr I think it was. I have 3 or 4 cases like these and a couple more that have shorter cracks in just the shoulder of the case. Is this the nature of this cartridge, just some bad brass or could this be a problem with the rifle?
Can this damage the chamber?
Is it anything to worry about?
TIA
