New Hornady .308 brass
I was lucky and found some in stock on Midway.
My question is, besides measuring and resizing what other case prep needs to be done in any to new brass before reloading? Thanks another newbie question |

None
Zero Nada But the case mouth may need to be deburred a bit. Use a No.5 Easy Out twisted clockwise and it'll put a better angle on the edge than conventional tools. |

Great idea on the EZ out. That never occurred to me. Running the left hand tapered grab screw backward should do an excellent job of burnishing the inside edges of the case mouth.

I resized and primed 6 cases. I won't get to shoot any until next week.

Maybe it's just me, but I always resize and check length on new brass. I've purchased brass before that was so bent it wouldn't even go into a FL die. Check all of it before loading.

Unclenick, that Easy Out idea was passed on to me by Sierra Bullets' first ballistic tech; Martin Hull, back in the '60's. I'd asked him what to do about their bullets' jackets being scraped off when seating them in normally chamfered case mouths. He said I had to make the case mouth's inside edge round/radiused so it doesn't act like a cutting tool. He also jokingly said "Shame on your for unbalancing our great match bullets by scraping off jackets more on one side than the other." His final comment was for me to cut off the pointy end of my deburring tool and only use the coned end on the outside of the case mouth.
Then I did some tests on jacket scraping and ended up running newely chamfered case mouths over a spinning bore brush and got the most round shape on the case mouths and zero jacket scraping. |

I found some more Hornady in stock, I was impressed with the quality of what I received in the last order.

Led0321,
Would you mind putting a few of those new Hornady cases on your loading scale and reporting what they weigh? I'd like to add that information to my data. Bart, Interesting that the information hasn't got circulated more. I first got onto the problem loading moly-coated bullets. I had occasion to pull one and was astonished to see no moly left at all below the case mouth. With a little experimenting I discovered I could sharpen a dowel like a pencil, turn it in my drill press and push case mouths up against it to burnish the chamfer and it would stop the scraping. I could also run the chamferred case over the carbide expander in my sizing die a couple or three times to burnish it, and that would stop scraping, but of course it tends to pull the neck off axis. The screw extractor in the drill press or in a hand drill sounds like the best solution. A little buffing to polish its surface may improve matters still further.
