Pawn shop 308

[RonMexico]

So I recently purchased 500 rounds of 308 ( 100 rounds new). I think the person didn't resize the brass bc it gets 90-95% in the chamber and won't chamber. Now my options for the experts on here are. I've been taking it apart with a rcbs bullet puller and I dot know If I should resize an reload the brass with the same powder and work up my load, Or toss the powder. The bullets are 155 gr sp and the brass is lake city. This ammo will be shoot out of an ar10

I would never shoot reloads you bought from a pawn shop. You don't know what the powder type even is. Why would you keep the powder?

What pawn shop even sold you reloaded ammo?

Toss the powder. Resize, trim, deburr and reload with fresh powder. You have no idea what was used, for all you know it could be pistol powder.

Well, not being one to work with unknowns, it would be easy for me to say dump the powder. ON THE OTHER HAND...take 10 rounds and load them with the average powder charge after resizing. Fire 1 to test for function...fire a few more over chrony to check for velocity and check the cases for excess pressure. Of course this would ideally be performed from a rolling block single shot, but the world isn't always perfect.

Well that sucks. Its gotta be way out of size if it wont feed in an auto loader.

Being as anal as I am with reloading I would probably not use that powder.

Why do all that, 20X11? To save $1.50 in powder?

AR 10's, like AR 15's and most "auto loaders" need full length resizing of the case. Not just neck sized as these rounds may have been, if they were sized at all.

shoot it out of a spanish small ring 7.62x51 hehe joking. anyway what i would do is find the average powder weight and reduce it by about 5 grains and work up from there. being that it wasnt fully resized makes me think the guy was loading it for a single bolt action he had, could have been making crazy super loads for a hot rodded large ring mauser. you never know

In "general" auto loaders have a little looser chamber than say a precision bolt rifle.

Fired from a sloppy chamber somethingoranother and only neck sized.


I'd probably back off and try to work it back up just for kicks. Is it a stick powder at least? Weighing in the 40 - 44 grain range?
