M193 projectiles......terrible.

I had some 147grn .308 seconds I got... the bases were malformed, but I didn't have a worry about the diameter because they were otherwise well made. They shot as well as anything else FMJ out of my M1a...

The OP's bullets are all over the map, and I would worry about the bullet diameter. Mic a few, see how consistent they are... then make your decision.

Those look like different lengths jackets, but well formed. Separate into two groups.

If my sorting were as simple as this ^^^and big Ole .308" pills I'd do it.
