Thread: Decapping military 5.56 and 7.72 Brass. Consumptive?

    though I do want to figure out how to get more space under the anvil so I don't have to dump the primers every six err eight 'thumps'.

    Get a block of wood - drill it out to fit the anvil, then drill a smaller hole for the primer to drop through into a trash bin.

    Why not just limit your brass to 223?

    I have never been a fan of .223. So I have way more 5.56 brass than .223.
    I'd rather be lucky than good, but I'd rather KNOW I'm good than HOPE to get lucky.

    I visually check every cases flash hole. The evil one's are of course berdan but another guaranteed pin breaker is IK 5.56 brass. It's used by Federal for there tracers. They have a very small flash hole and a lot of bright red primer sealant.

    "why not just limit your brass to. 223" wheelman

    Well for starters there's the issue of dimensional differences. There are 8. The. .223 is smaller and therefore goes through more expansion in a 556 chamber thereby stressing the 223 brass.

    Differences in BRASS or differences in CHAMBER?

    I'm aware the chambers and load pressures are different, and other than MIL 5.56 cases being thicker with less internal volume in some cases... I'm unaware of external dimensional differences... can you clarify?

    So.... you ARE saying there is a difference in measurements of the BRASS?

    OK... because if you have something other than what's cited above, I'd like to see it AND the source.
