Chamfering

[Heather]

So I'm on the newer side of reloading, only been using new casings. Just got some pulled brass and was aware of some burrs. What about chamfering? Is that something you all view as important? I saw redding had an inside chamfering tool and I did just get one with my Hornady Duo Prep Tool. This may be a stupid question to you all but did not see it in my reloading books (maybe I didn't look in the right place) so was just wondering what your guys' thoughts were?
Thanks

I always chamfer and deburr. Its especially necessary after trimming. Dont want the nice sleek bullets scratched or scuffed. Most any deburring tool is fine. There are difference in angle of cut. 30°and 45°. Hope this helps. Welcome aboard

Thank you!!

Lightly chamferring inside case mouths is a good practice. You only need to do it once with new brass, and again each time you trim brass

Glad to hear, I was starting to do that

The only stupid question is the one that isn't asked.

When you get down to details, even new brass should be chamfered on the ID of the neck.

The mouth of the neck can scratch the bullet jacket and create issues with seating, so learn to be sensitive to the force when you seat bullets and you will even be able to detect the difference between seating with brass that does and does not have that chamfer.

No reason to go overboard with the tool either. You just need to make it smooth so the bullet can seat. Just a few light pressure twists is good.

Thanks guys!!

...always during every reload, but very very very lightly.

Only because no one mentioned it:

New brass will have cases mouths that get out-of-round due to packing/shipping, etc. It's a good idea to run new brass through your sizing die before attempting to chamfer/deburr the cases.

Speaking of deburring/chamfering tools: I've been using the same one by RCBS for about 35 years, and have wondered if I should replace it with a new (sharper?) one. Any thoughts?
