Do you chamfer and deburr NEW rifle brass?

    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
    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?
