Back in the mid 70's I joined a local rifle club and spent Wednesdays shooting a variety of handguns. The local APs from Fairchild, AFB were using our range to do some practicing for a grudge match they had with a British AP unit. It seems they had sent a dozen of their service weapons (M-16's) over to the Brits who in turn sent a dozen of their service weapons (FN L1A1) They just happened to need a another body to fill in a slot and I was available. We were shooting the FNs at 600 yds, I had experience with the M-14 and G-3 but had never spent any quality time with the L1A, I was impressed. At the end of the day the Tech Sarge that was running the show presented me with a small coffee can full of .38spl cartridges, I looked at one and thought it looked wicked and asked him what they were . He said they were 158 hollow based wadcutters inverted over 3.5 grains of Red Dot, then added "Thats our duty load, have fun and thanks for your help." They were very accurate.
