these comments now for the .30-06 and .308.....not the .223 military brass.....

It is fine brass....very fine. It will require reduced powder consumption because it tends to have heavier thicknesses. You MUST work up loads.and that' s not hard to do.

Removing the crimp is easy....there' s tools available to do it.....you can use a simple deburring tool if you wish.

It' s a matter of how much free time you have to devote to this. Given the committment on your part, you can have a lot of cheap beass of high quality.....but you pay for it in time.....there' s no right answer.
