Case prep on unfired Lake City 7.62 brass? Login/Join 
Member
posted
Hey all-

I got a deal on a pile of demilled Lake City 7.62 brass. It's unfired with primers intact. They pulled bullets and dumped the powder and sold the primed cases.
My question is: How much brass prep would you do on these? Round out the case mouths, fill and seat? Trim, chamfer, deburr, fill and seat?

I will be shooting this out of my 700 Remington bolt gun.

Thanks,

Bruce

A few years ago, I bought 2k Austrian pull down 7.62 cases w/ primer. I just loaded them with powder & a bullet & shot them. Worked very well & accuracy was just fine.

I would just ensure the mouth is round, then check length, no reason to get to the case body. One shouldn’t need much lube, don’t want to chance primer contamination.

Length ‘should’ be good. If not trimming, champher/debur could be optional.

I’m talking casual shooting or hunting rounds, one can take it to higher levels if desired. Once you have a handful do some testing before loading 500 rounds.

I think I will check length, neck size with the bushing die, fill and seat.

You can just put a caliper to those necks to check a few, no need to check all of them in a die. You might need to bell the mouths just a bit to prevent skinning the jacket when you seat your new bullets. Then taper crimp a bit ... all depends.

I used to get a lot of brass from powder valley before they started reconditioning all of their brass and usually all I had to do on primered brass was open the mouth up a bit, enough to seat new boolits, then recrimp lightly.

Then I started buying from Top Brass and, back in the day it came completely reconditioned and primered and ready to go. It spoiled me a bit.

You are a lucky man to get that brass .... you might get 6-10 reloads out of that brass if you don't overwork it and learn to anneal. Congratulations on your good fortune.

Yeah, I am excited to get this. I scored it at Midway. Unsure if they have any more.
I was cautioned that much of the fired LC brass is from belt fed machine guns with huge chambers and long headspace and basically trashed from one firing. Getting Lake City unfired was a definitely a win.
