[QUOTE="8x68s, post: 2768366, member: 109828"] [B]Can one of you previous posters tell me how you know a projectile is 'suffering; from cold weld?[/B] I know how hard it is to use inertia hammers to seperate a bullet from the case (milsurp ammo). [B]But I have no way to measure this so called 'cold weld'.[/B] FWIW since reading about the dangers of 'cold weld' I now use graphite before seating my rifle ammo...
