Should new brass be lightly deburred inside and out before using? or is that done already? or, just depending on brand? Thanks! :)

As a rule, I fully prep (even) new/unfired brass: FL size/neck expand, uniform the primer pocket, check/trim length; and chamfer mouth. Done once, it's done.

Since it's become a habbit over the years, I even do it on El Primo (Lapua) :neener:

I have never seen new brass from any manufacturer that didn't need inside and out side chamfering. Inside chamfering is required to seat a bullet easily for the first time, especially if you're using lead bullets and don't want to shave lead. I usually inside chamfer all once fired GI brass I acquire for my 223 and 308 rifles .

I've got one of the RCBS inside/outside hand deburring tools so I will be sure to use it before pressing the bullets in the cases. Thanks for the info. :)

Size it, trim it, chamfer & deburr it, or just load it and shoot it. I choose the former.

Always chamfer new brass, it is quite rough as furnished. I've had a lot of headaches trying to get it through my progressive press as it sticks to the powder drop.

I always chamfer and debur new brass. It's easy to do and doesn't take long.

The edges are usually sharp on new casings. Inside and outside chamfer is a must.

The subject of prepping new brass seems to cycle through every forum related to reloading every few months. This target, like all targets I shoot with new brass, was shot using new, untrimmed, unchamfered, unsized, unscrewed around with brass.

I'm sure it will relieve you all to know that I do resize fired brass and even trim it if needed.

If it ain't broke, don't fix it. That said all new brass gets the once over. Whatever it needs it gets.
