    Question about 55 grain ammo in the ACR

    I wanted to see what type brass cased .55 gr ammo would be best in my ACR that has a 1-9 barrel. Any suggestions would be appreciated.

    I'm no expert, but an M4 barrel should be perfectly suited for XM193, as that's the typical military round. But I've also found that the ACR is perfectly satisfied with everything I've fed it. I think the only thing I have refused to subject it to has been ammo on the order of Wolf or Tula. Bear and above (brass or steel) it seems to like just fine.

    I don't use the older 1/9 barrels anymore in my ACRs, but when I did they always liked Federal XM193 and PMC 55gr .223.
