[QUOTE="jdyoung, post: 2024203, member: 113391"] You don’t want any burrs on the inside of the primer flash hole. That’s a given. I have always wondered what the affect of the chamfering of the inner flash hole has on the flame from the primer. The an inner flash hole de-burring tool has about a 3/16” shaft and approximately a 30 degree shoulder on the cutter. So does that 30 degree chamfer at the inside flash hole “mouth” cause/allow the primer flame to flare more evenly throughout ignition of the powder charge ? I set my inner flash hole tool up to only chamfer 0.010” of the inner flash hole. That is enough to remove the burrs . But I wonder if a bit more say 0.015” – 0.018” would give an advantage. If it does, do the manufactures that drill the flash hole chamfer that inside flash hole ? [/QUOTE]
