processing 223 brass question

[poker2112]

im trimming alot of brass on my forster trimmer........... i know its good practice to chamfer necks clean........... would it make a huge difference if i didnt ???when loading in station #1 (dillon550b) the burrs are gone and inside neck is clean ........dont know if the burrs got smashed down or press off(feels good to me)...........crimping is same........dont see how it would make a difference .thanks

if you're using a BT bullet and loading blasting ammo (not precision/match ammo) then i wouldn't sweat it

even if i was loading precision ammo/match ammo theres really no burrs.....just wondering if not chamfering would make a difference ?thanks

A sharp inside edge will skuff your bullets as they are inserted into the case. A burr on the outside of the case will affect the uniformity of bullet release upon ignition.
If there is no burr on the outside and at least; a bit of chamfer on the inside, you are good to go.

well these are plinking ammo ................do i need to worry about putting a mark on the bullet???? not much burr on the outside

Less than 200 yds? No. Shoot-em-up! You'll never see the difference.

thanks !!!!!!! its a pain trying to clean all that brass .........just wanted to make sure

Tell me about it! I shoot across the course and at 300 and 600yds, brass prep is critical. At 200 yds, the bullet gets there too fast to make any difference.
Good shooting.

Not chamfering outside will in time scratch your die leaving marks in the brass. These scratches in the neck area will in time make the neck split. You will then have to send the die back to the manufacture to have it polished. This happens with neck or full lengnt sizing dies. Just the dirt left on a fired case will scratch the die if you dont clean the brass. It takes a while , many rounds.

Blasting ammo. No, but you should anyway. Anything you want accuracy from. Absolutely yes.
