Anyone here debur the flash hole?

[PistolPete75]

I just got my RCBS Trim Mate Prep Center, so I am finally starting to debur the neck, chamfer, and clean the primer pocket. Does anyone here also debur the flash hole? Is it worth the extra time?

This question is for precision rifle shooters.

I have a flash hole deburring tool that I hardly use. I used to use it on my Lapua .308 brass because back then, a lot of the lots had burrs on the flash holes even. It's wise to get one. You only have to debur the flash hole on a piece of brass once.

I always debur the flash holes on new rifle brass (.308, .45-70, .45-90)

Can't say if it makes a tremendous difference, but you only have to do it once.
I don't bother with pistol brass.

Now let me flip the question, how many times do you have to chamfer? Is it only after you trim? Please say yes.

Well, you chamfer after you trim brass, but you may trim several times during a piece of brass' lifetime. Just don't be stoopid and chamfer first ;)

See the thing is, i've been watching my brass very carefully the last 3 times I shot it. Brass is holding up very well, with no signs of streching or cracking. I've already shot it three times, and it is in great shape. Without fullsizing it (just to see the present condition of the brass), brass that was shot three times fits my case guage perfectly! I figure if I start chamfering it now, and clean the primer pockets really well, and fullsize it again I can shoot it perhaps 2-3 more times, before I have to trim it, and start the whole process all over again. What do you think?

See my 5.56 brass, I load in quanity like 500-700 at a time, so I like to bang it out if I can but I still want to get reliable, accurate ammo.

oh by the way, it's 5.56 gutamalan brass (very thick!)

[Rule .308]

All of my .223 and .308 brass that I run through auto loaders I full length size everytime and it needs to be trimmed pretty much everytime. Necksizing only it never needs to be trimmed. I have yet to run into a pistol caliber that I have had to trim. I only bother deburring flash holes on the stuff that I want to be really accurate, general blasting ammo I do not go to that extent. The RCBS prep center is pretty cool though isn't it? I just wish the thing would spin about twice as fast.

I debur flash holes on all of my brass - I notice that after I clean the primer pocket out, deburring makes more crap fall out of the flash hole... Well, I don't on most handgun, but a must for rifles... Did not try to see if there is a noticeable difference but somehow doubt it - more of a peace of mind that I have wider flash holes:43:

I deburr my long distance varmint & competition brass except Lapua, which don't need it. My regular hunting/plinking brass I don't (That's like putting a spoiler on a Yugo, not enough improvement to see)

Chamfer your brass when new and after you trim it. All it is for is to get the bullet in the case without damaging/marking it and doesn't effect the length of the case
