I've shot tons of it. As the machinery for M118 (white box) started wearing out they stuck them in brown boxes and called it Special Ball, for sniper use (sic). Military teams made Mexican match out of M118 already. They demanded better bullets so the M852 came out (168 SMKs), we still Mexican Matched that for 1000 yard shooting.
When we first started getting 852 we found some guns didn't like it, some did. We had two types of barrels in our M14s, the Military Match 4 grove barrel and the Barnett Douglas based 6 grove barrels. The Douglas barrels like the SMKs, the 4 grove barrels didn't. The 4 grove military barrels liked the 173s better then the SMKs. At the time we getting a mix, some M118, some M852. I started issuing my rifle team two rifles, so they could shoot what ever we got.
In making Mexican match I ended up with 1000s of pulled 173s. Was going to sell them then decided to save them for offhand practice. But then I got into the CMP's vintage rifle shooting. I found these 173s worked good in the old military rifles (M1903s, M1917s and Garand). They really worked great in the two grove Springfield barrels. I just loaded my last several hundred last week.
Anyway if you have the M118 Special Ball and want to shoot them in matches, Buy some SMKs and Mexican match them. If you can get a 4 grove military barrel, shoot them as is.
As to $1 a piece...not me. I still have a few hundred hanging around, I'll use them for offhand practice or plinking out of my FAL, but I certainly wouldn't buy any. Not even worth making Mexican match for me now, Since I'm retired and have to fund my own shooting now, I'll just bite the bullet, buy Winchester brass and Sierra bullets. My M1A and Model 70 target rifle sure likes that combo.
