Do you chamfer and deburr NEW rifle brass?

[Rule3]

Finally found some brand new (yes it's out there) 30-30 brass. I know I need to size it, but what about chamfering and deburring the case mouth. I am so excited, never had new, new brass

 

[rcmodel]

Yes.

Very slightly.

rc

 

[Zeke/PA]

Very slight chamfer inside and outside of neck and size the neck also.

 

[alsaqr]

The new case mouths get a light chamfer/debur job. The flash hole is deburred at the same time.

 

[Walkalong]

Yes.

Very slightly.

Same here.

 

[morcey2]

Chamfer on everything. Deburr flash hole on everything but Lapua.

 

[witchhunter]

I FL size, trim, deburr flash hole and uniform primer pockets on all new brass...just so I know it is all the same when I load it.

 

[dragon813gt]

Yes on all accounts.

I think the OP is referring to chamfering and deburring the case mouth. Flash holes and primer pockets are a different issue.

I also chamfer and deburr new brass and once fired. The factories typically don't do it.

 

[texashunter]

trim, debur flash hole, chamfer and debur. start with all pieces equal

 

[Crashbox]

Ditto here as per RC and Walkalong.

 

[gamestalker]

I do, whether new or once fired, I always run it through the FL die, trim, and then ream and chamfer.

Neck-size o correct anything thats not already perfectley round.
Then just barely touch the inside /outside of case neck on reamer
Flash-holes on everything except Lapua, get spun a few turns

I take that as a yes then Thanks

Never have done a flash hole? How necessary is that on a 30-30??

 

[steve4102]

There is really only two times that I chamfer the case mouths.
1) New brass.

2) Trimmed brass.

 

[Centurian22]

So does this apply to ALL new brass or only rifle? I know most say they never trim pistol brass so where does chamfer / deburr fall?

 

[dragon813gt]

For pistol, anything w/ a roll crimp. I like the crimps to be uniform. I really should trim brass that needs a taper crimp because it headspaces off the cartridge. But it's worked fine w/out doing it.

Chamfer, deburr, every reloading, even new brass. Flash hole deburring, i do about every 3-4 reloads, and yes new brass gets flash hole deburred before loaded for first time.

 

[jwrowland77]

Since all the new brass that I have gotten needed to be trimmed, yes chamfer and deburr the case mouth. I also neck size only and deburr the flash hole as well.

 

[PJSprog]

Like others, slightly inside and out on the mouth. Run your fingers over a few of your new cases and in short order you'll understand why.

 

[pleopard]

Does it matter when you chamfer/debur? Like before/after sizing ... before/after tumbling ... ?

If you chamfer before at least neck-sizing, you'll likely be chamfering an out-of-round case mouth. I don't think it matters in relation to tumbling. Also, depending on the tool used you should deburr after sizing/trimming/chamfering. Most of the deburring tools depend on consistent case length and a round case mouth.

Yep.
Just a lil bit.

 

[FROGO207]

I treat new brass the same as OF brass. Yes I do a complete going over from sizing, length sizing, and lightly chamfer/deburr as needed. If you do not bother do all that AT LEAST make sure it is not too long and the empty brass will chamber before loading it..
