Re: Deburring flash hole Lapua brass? + grns water 338 LM vs 338/300RUM
I still deburred the flash holes on the .338 lapua brass used in the .338 MOAG because even if there are no burrs, it will still help powder ignition to have a nice smooth bevel on the inside of the flash hole. I think it helps, and the groups at 2k with the MOAG said, "thank you!"
If it's not far, it's boring.
