I've been working with some once fired Lake City brass. Once fired in my Rem700 .308win.

Even after resizing them and trimming them back to 2.005 (trim to length) they are a little little snug when I cycle them and close down the bolt. These are unloaded resized and trimmed cases.

I even trimmed some back to 2.000 some of those work smoother- I checked the calibration on my dial caliper it OK

is there any problem with loading and shooting some cases that are trimmed to below the 2.005???

I never used to have this problem with reused Remington,Winchester brass even after multiple loading.


Wonder if it's just something finicky with this mil spec brass?
 
Lake City brass is thicker then most other brass, and I would make sure to just bump the shoulder and then check them. I have never had any problems with the Lake City brass that I have.
 
sounds like you need to screw the size die down a tad more,,the LC brass is tough and the press will actually give a little,,lower the handle all the way down and screw the die in till it touches the shellholder,then screw it down 1/16 turn and try that and screw down another 1/16th turn untill it closes easy,,back the decapping assembly up a little or you will break it,,
 
Be careful with the Lake City brass. I had a problem once with a set of Lake City brass. It developed excessive pressure and the bolt had to be hammered open. That was years back before I knew any better and didn't measure loaded round neck diameters with unknown brass. It's got a lot thicker neck than most brass which can result in an oversize neck diameter in loaded rounds. Take a micrometer and measure some factory cases fired in your chamber and then measure the necks of ammo loaded with the Lake City brass. You really need a minimum of .002 for safety's sake and that's a tight tolerance. You may not have that. A combination of oversized brass and a minimum chamber could be disastrous.

This may or may not be the cause of your problem but it's something to keep in mind.
 
just to help clarify, this is Lake City Match-not just some regular LC stamp heads from an auto rifle. And they were once fired- fire formed in same said my Rem700.

If that helps.

btw, just from visual appearance-the neck meat looked beefier as I noticed just after trimming them.

I'll check some neck diams after loading!


I'll keep these other thoughts in mind.


Thanks
