I have a bunch of 223 brass from our local SWAT team, and access to lots more of it. I am about to purchase a Dillon 650 and intend to crank out multitudes of 223 rounds for my own (first) AR platform. I am new to reloading.

I have noticed that alot of the brass (almost all of it) has significant shoulder damage (not sure if I am using the right terminology). Big dents where the case narrows from "powder charge holding area" to "neck" where the bullet will be seated. Will these dents "blow out" upon firing after reloading? Will they tend to jam? Is there some way to "prep" these cases prior to reloading? Will the pressures be too high if I load with powder weights that count on an "undamaged" and therefore "true-capacity" case?

I am wondering if I am going to experience issues, and whether or not I should be including another step in the reloading sequence to deal with this issue. I have access to LOTS of this brass and would prefer to NOT get it from another source...

Sorry for my lack of experience....

Sounds like the SWAT boys are shooting on concrete - pics will be needed, but if it's just the necks being flattened a bit, that will straighten out in the reloading process.
 
Best way I can put it, if you squeeze a pop bottle and make one side flat, but are able to squeeze it the other direction and that dent pops out then its good. If you make that dent to big that you are no longer able to squeeze it out then you have a wrecked pop bottle (or in this case .223 brass). Now just replace pop bottle with .223 brass and squeeze with re-sizing.
 
Welcome to the board. Small shoulder dents are nothing to worry about, they will iron out on the first firing. It will not interfere with the "powder charge holding area" as you will be loading a recommended starting load from a reloading manual that you have purcahased and read from cover to cover. It will also teach you the proper terminology with regards to ammunition, then you won't get talked to in a stern manner by the cranky old bastards in the forum.;)
 
Thanks for all of the comments. Unfortunately I don't spend too much time on the computer so I am not as timely on responding as I am sure many would prefer....

I intend to purchase a Dillon XL 650 and all of the attachments...any idea how to do this in the cheapest manner possible? I have a passport and could roll across the border, and could set up a mailbox on the south side. Are there any dealers for Dillon in the Lower Mainland?
