115 gr
I don't shoot 124gr or 147gr training ammunition unless it's Speer.
I also picked up a case of 55gr 5.56 Lake City XM193 for $0.34 about a month ago. The deals are out there. I can still get HST LE under $0.70/rd and I have been finding deals on most things. The only thing I have had trouble acquiring recently is 12ga Buck or Slugs.
Both arms are torn up so I prefer 147 ammunition even though you pay more for the 147.
Are you interested in 150 rounds of 124+P Gold Dot which costs slightly more than the HST.
I will sell my last 3 boxes of 124+P Gold Dot in Walker for $90.

FYI, Federal had a 20% fixed price increase recently, so regardless of what you were paying, you will be paying increased prices from here on out.
Mine is recent production in the new boxes.
