[QUOTE="Stratmeister, post: 328511, member: 21225"] The Lapua brass (and maybe Norma not sure...) has the flash holes drilled whereas most other brass has the holes stamped through. This is the reason the Lapua brass doesn't need the flash hole cleaned up. The stamping process used by say, Winchester and Remington, can and often does leave a burr on the inside of the case which 'can' hinder the even ignition of the powder. I always deburr/chamfer the inside of the flash hole of brass when its new. You only have to do it once, and I think it's worth the effort. You'd be suprised what drops out of the case after deburring new cases sometimes... [/QUOTE]
