de-burring question?

[.444 Marlin]

I know your supposed to deburr the flash hole in the case but are you supposed to deburr the flash hole inside the case and in the primer pocket?

I do debur the inside and have never debur in the primer pocket.
Good question, never thought of it before.

I think because most of the holes are punched, that the inside only is required. If drilled, none required.

I only use the deburrer on the inside of the case on new brass. I do, however use a primer pocket uniformer on the outside even on new cases and then use the same tool to remove powder residue on fired cases each time.

Is that just inside the primer pocket or incase the case neck?

primer pocket uniformer goes in the primer pocket


flash hole uniforming is inside the case to the primer hole

First size brass, then trim to length. then chamfer and debur inside and outside of case mouth, then uniform flash hole inside, then uniform primer pocket outside, then polish case, then charge with powder and seat bullet. That's my order....sure get's tedious sometimes but it pays in good ammo. That doesn't include the match calibers that get the cases and bullets weighed and sorted by weight and bullets sorted by ogive length. It goes on and on.

I have some 308 and 25-06 brass that I deburred the flash hole on,,I can not tell any difference in accuracy or velocity deviation ,,IMO,

it can not hurt,,but I never got any better groups by doing it

I think there is a lot of little things that dont really make a difference most of the time. But when you do all these little things it just gives piece of mind knowing that this is some of the most accurate ammo I am capable of loading. Or something to that effect.

I agree,,I just wouldnt expect a load to go from .75 to .50
