Several passes to size brass?

[CJ]

Thats what I figured. So would something like this more than likely go away with a press that doesn't flex as much/at all?

That isn't going to change anything. I run that S&B through a single stage, and I can gorilla that mofo and make it my bitch, but the brass is too thick, it springs back and never chambers right. Some brass you just have to learn to avoid. After time you'll recognize which head stamps to avoid. It happens from time to time. For volume loading I would set the headspace at minimum, to give the thicker cases more room to expand and still be within spec.

One thing I'm not sure if you mentioned. Are you loading 7.62x51 or .308 - the cases are different. You mentioned LC - that's NATO brass, and that's going to be thicker. You also need to load these differently. My guess is it's the NATO brass that's not resizing, because they won't resize the same as commercial .308, it's a much thicker case.

The only reason i did what i did with my 308 was no issues with different hardness of brass. Its all the same.

On my .223 its all mixed and some took two pulls mainly lake city. Its a habit for me to run the handle all the way down once and then pull it out a little and push it down again. Basically sizing it twice and not even noticing because its a habit.

It isn't all the same. 7.62x51 is different.

As long as the rifle isn't a 7.62x51 chamber or certain action there won't be a problem. Now if using a 7.62 case there will be a variance in pressure between the two but depending on load it may go unnoticed.

Cj read my post where i said i bought all new .308 brass so it was all the same.

Plus i want to see how many loads itll take till the neck cracks. Im up to 8.

Yea I think I'm going to go through mine. I have some NATO brass mixed in, but some of the LC stuff doesn't have that little NATO circle with the cross in it. Still NATO? Either way, I am not loading these up to full power, rather close to the min load actually. Just soft plinking rounds so I don't think chamber pressure is an issue.

They are loaded quite lightly, so I will just toss the SB brass and double run the NATO stuff. Its going in a 308 chambered gun

Externally they are identical, internally they are different. They also resize differently, the nato cases require more pressure as they spring back more.

As for how many times you reload, it depends on whether or not you started with an annealed case, and whether or not you anneal the case as you reload it. You can get 20+ times if you're annealing.

Yes, the circle with the cross, "The Nato Mark" just means the ammo meets Nato specs as to bullet weight, velocity, and pressure for one of the standard offical Nato loadings. Not all LC will have this mark, and not all 7.62x51 will have this mark, same with 5.56.
