Depends on how often you want to practice IA/ Malfunction drills.



Seriously though. Brass length could be an issue depending on your chamber. A tight chamber might not like + .010", whereas some more forgiving chambers might be OK. Course if you have multiple weapons in 5.56, each could have variations in the gun that could be an issue as well. As for the pockets, keeping them clean helps make sure it goes bang instead of click. For myself, I clean, trim and deburr all brass. There is a difference between my blaster loads and precision loads. Blaster stuff, Im a little more forgiving on specs, how clean i get it, mixed headstamp, etc. When I'm loading the good stuff, I get pretty meticulous on cleanliness, length, case thickness, headstamp, and so on.
