Brass prep.

[Michigan Chris]

Fairly new to reloading and was prepping some brass for my 7mm RSAUM and need some help.

Basically I would like to know what steps I need to do in what order for the best accuracy chances.

For example, should I deburr the brass before or after running the brass through the resizer?

Does it matter if I deburr the inside or outside first? Should I weigh the brass before or after the prep?

The factory remington brass is a bit shorter than the OAL of 2.035, I was only getting about 2.028 to 2.032 033 if I work the brass with the deburrer? Is this going to affect the accuracy as I don't thing I can trim it because it will go down to 2.024 or so?

As of now, I weight sorted the brass within 2 gr, ran it through the resizer "neck mouth only" then deburred the outside then the inside ? OAL's are somewhere between 2.0295 to 2.033?

Best Regards.

I don't think that brass prep is at all a waste of time ever. Learn what you can friend, brass prep is always beneficial.

Thank you Sir's, any and all help will be greatly used.

Recently purchased a custom 7MM RSAUM with a brux barrel, borden alpine action, Mcmill. a-5 for long range anything! Coming off a 7mm Rem mag Blaser I couldn't get the "one holes" I wanted out of. Anyway, I think this SAUM is capable of everything I want to do and if I'm going to be prepping brass I might as well spend the time doing it right so I'm not dropping F bombs at the Range/field. If your gonna be a bear be a GRIZZLY!

Just follow the numbered steps and you should get good results. Jacob guarantees it! Plus, he's a tough competitor. Just wish he'd put out those darn cigarettes, when he goes to the line.
