Lake City Brass Question

[lotus]

I saw an interesting question on another board about whether Lake City brass found in Federal XM-193 and Black Hills remanufactured ammo was technically "military" brass.

I have quite a bit of XM-193 I'd like recover the brass from some day. Do I treat this stuff as thicker walled military type or normal brass?

Only way to tell for sure is to weigh it and/or do a case volume study using water. Neither is entirely precise, but should do the trick. Of course, you would need Lake City brass to compare it to.

Keep it seperate

I agree with Sven in comparing the brass weight. In using your normal hunting load try bench resting and see if there is a different point of impact on the target from your other brass. I don't see a problem unless you are preparing max loads. In any case you may want to keep that batch of loaded brass seperate from your other loads because of the possibly different POI.

I prefer GI brass for any caliber in which it is available as the caliber and weapon was invented for the military and the GI brass was made to military specifications (MILSPEC)for that weapon and civilian brass to me is a cheaper quality version as far as strength and longevity of its reloading life is concerned.

You should probably check brass weight, but the Federal XM193 brass is original LC brass that was meant for military ammo production.

USGI .223/5.56 LC cases are the same weight as their commercial equivalent. Go ahead and do the water volume testing for yourself if you like. The .308 and .30-06 LC ARE thicker than commercial.

2.5k of LC Match brass arrived this week - let me tell you, that's HEAVY stuff.
