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:D;)

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

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.

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.

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??

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

2) Trimmed brass.

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?

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.

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.

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.

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.

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..

Chamfer everything but pistol brass that is going to be flared.

Yes, On the 30-30 brass I just got (Remington) you can see the case mouths are not round, Some are downright flattened on one side. I just full length sized them all and now will trim them a bit as they are almost max length. Then chamfer and deburr

It probably is good to do the flash hole but I never have on 223, 30 carbine or 30-06. Never did one on any pistol calibers.
I suppose if one is a bench rest shooter every little thing matters, but I doubt it will improve my shooting to be worth the effort. Heck, I do not sort brass by head stamp either.:uhoh: 99.99% of all my brass is range brass from the days when the fields were lined with gold (brass):D

You would know if you looked at the case mouth and tried seating a few bullets. Or you could just do what everyone tells you. :)

I just started reloading rifle (.222 Rem) ; I've been reloading .38 Special for a few years. I full length resized, chamfered lightly, but have a problem getting the bullet started when I try to seat it. Do I need to chamfer more?

Yes. I also de-burr the primer hole. Rod

BT or Boat Tail-Beveled Bottom Bullets should seat fine without Chamfering, loaded 1000's of FMT-BT and never chamfered any cases
Now FB or Flat Base Bullets are easier to Load with a Chamfered case..

BT will balance on there own and load great.... FB will need to be Guided into Bullet Die so do take a bit more time to load

I inherited about 1000 flat base & spend more time picking them up than loading.:banghead:

Yes, and I trim them if they're not the same length.

In 1999 I started handloading with a Rockchucker kit that came with a Wilson 60 degree chamfering tool.
At some point I was researching everything Bart Bobbitt ever posted [40 shots at 600 yards, all inside 2 inches]. I found a 1992 use net [before there were gun forums on the WWW] where he said that not chamfering would cause the bullets to get scratched. He used a #5 easy out instead of a 60 degee chamfer.
rec.guns 1992 post (https://groups.google.com/forum/?hl=en#!search/rec.guns$20bart$20chamfer/rec.guns/1w1VAqj82rw/FyTqQ-OTBusJ)
As I measure the old RCBS OEM Wilson it is 60 degrees.
The newer RCBS 22 degree VLD chamfer looks like 25 degrees to me.
And a #4 easy out looks like 7 degrees and needs a left hand twist to cut.

Brand new brass is often in need of certain fixes: necks not round or not cut off square to the case body or not uncommon.

With a batch of new rifle brass, I test chamber to ensure the shoulders have been formed in the right place. I have yet to find a piece of unfired brass that won't chamber, but you never know. Then I neck size the lot. This ensures uniform neck tension, and if any mouths are flattened at all, this step will round them.

Next I find the shortest one and verify that it's within spec length, and I "trim" it just enough to square the mouth to the body. I trim the rest to match.

Finally I debur and chamfer the necks and uniform the flash holes. Now they're ready to prime and load.

Yes. It's part of the drill. Case preparation is a big part of successful reloading. So you want to skip it?
