Flash hole chamfer
Flash hole chamfer
I have been in the habit of chamfering the case flash-hole with many rifle calibers.
With the .223 Rem 5.56 NATO I have found many cases to be ragged at the flash hole.
Does this really help ignition/accuracy or am I wasting my time?

You're wasting time unless you're a serious competitor at 600+ yards - or hunting mice at 300.

I did that for a while when I first started to reload. Couldn't see any accuracy difference, but the club only has a 100 yard range.

Since it only has to be done once per case and I don't know how much ammo I'm going to use at different distances I do it for all the cases the first time.

Do it for all,...
I don't use different loads across course (168's or 68's)
do it to all once.
It make the primer flame more consist when forming and eliminate weak flame when it flows around any burr @ flashhole.
A long length #2 center-drill from a industrial tool house does the trick for me.
