I competed in IHMSA at Rio Salado Range in Mesa, Az. Back in the 80's. At the time I was competing in IPSC, PPC, Bullseye & service rifle matches. I enjoyed the metallic matches more than any of the others.
The matches were much more laid back than the other disciplines I competed in.
I loved shooting the steel, instant feedback, you knock it down to score or you don't. Simple & easy. This could also add to the pressure when you knew you were cleaning the rack and got to the 5th or 10th shot.
I shot long range production for years with a Ruger 7.5" SBH, shooting Hornady 240 gr JHP's over 20 gr of 2400.
I eventually moved to a 10" 7mm TCU, shooting 139's & for 200 yds, the 154's.
Out in the desert, the wind blows occasionally and as a result, sometimes the rams had to be "hard set" so that we could shoot w/o the wind blowing down our rams at 200 yds.
I learned a LOT about shooting at 50,100,150 & 200 yds with open sighted Hgns.
The turkeys at 150 were always my nemesis's.
I have a box full of these pins some where, had these in an envelope in my loading bench.
