    I was just messing around online yesterday and found the 6x45 round (.223 necked up to a 6mm). I was just wondering if anyone has one of these in an AR? Sounds like you'd just have to rebarrel it and everything else would be the same. Just looking to improve on the .223 without having to spend a bunch of $$$ to change out the whole upper. How much of a difference in drop is there with both shooting 75gr bullets? I was thinking of this round for p-dogs out to 500-600 yards, but mainly within 300. Thanks for the info!

    I have a 6x45 and would take it over a 223 imp but thats just me, they are very close in drop out to about 400yards and the 6x45 carrys more energy and you can use the 6x45 in some states to hunt deer and its a great round to start a new hunter with. the 6x45 is one of the least picky rounds I have ever loaded, I mean you can load alot of powders and bullets and get great accuracy with almost any combo. I have shot many deer with mine with the 85 partition and havent had one run more than about 30yrds,while I keep my shots under 200yrds I feel it would work fine out more if realy needed but I have bigger and faster stuff for that.

    exbal says
    my varmint load
    sierra 80grn blitx boatails @ 3025

    12.2 drop at 300yrds with 100yrd zero


    223AI
    75grn@ 3000fps (maybe you can get more but this is a what I found online)
    11.9@300 2 27.5@400

    everybody likes what they like but feel the 6X45 is a better mid range varmint round and can be a great closer in deer round.also to get the 3000fps I have listed for the 223ai you would have to load them very long and lose the use of the magazine in a ar from what I know but I am no expert
