25.0 to 26.0 gr with 64 and 65 gr, for me, up at the top of Hodgdon's listed .223 data; wish they listed 5.56 pressure data. Not really heavies now that I think about it, kind of mid-range these days. I haven't had any luck with 73 ELD's yet, but that doesn't seem unusual.

That's why you get ASC's. cool



The rule of thumb is to add 1.5gr of powder to go from .223 to 5.56 velocities. Of course you need to work up, and this is just a rule to give you an approximate upper limit.

You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.
