The 6mmAI is a good round. Don't expect an increase to 240 Wea. vel. or any larger cased 6mm round, but
a decent increase, let's leave it there. For what the round can do, go to the Sierra Manual, Edition V & consult them, they have good research to offer & no need to repeat here, anyone who wants to know can read it there. Look at their loads, I would rather not see loads that are over there's & not pressure tested as they do, so don't post them here.
As far as bullets go, 100 Part, Barnes TSX & Interbond would be my first tries.
BTW, if this becomes a "what can I get with an Ackley" thread or not get, I will shut it down.
