Back in the 80's, Uncle Sugar surplused some WW match made for the US Army. 230 gr FMJ in 50 round boxes labled "Match".
OMG! that stuff was uber accurate, even with my then only .45, a skinny sighted WWI M1911!

I had bought 5 boxes from a vendor that had cases and cases of it at a gun show. I shot one box later that week and realized how good the stuff was and called the vendor less than a week after the gun show and he had sold out all he had. I wasn't ever able to find any more.

I did use the 4 boxes in 3 gun matches that year. I did better on pistol in those matches than I ever have!
