That is ringing memory bells.
We started at 50 yards and I only shot it once, so they ,may have shifted. Basically they handed us a box of ammo, two speed loaders and the gun (we must have had holsters strapped on already) and told us how it was shot.
I can't remember range specifics, but at a couple of points you were on a timer and it was obvious that is where the speed loaders came in. Rest of ammo was loose in your pocket (I think they issued us a jacket for that).
The one part that I was not sure of was a left handed shoot on a barricade. I did fine. Years latter I figured out I was quasi ambidextrous. Someone noted I did card dealing the wrong way. I wracked up my right wrist and learned to cut left handed (I could hammer nails left handed to but it was iffy though with practice....)
The fun part was when I got done the range guy is totalling up the target, after his third go through I am thinking, damn, it looks ok, what did I do wrong?
He then asked me where I leanre4d to shoot. Gravel pits? He looks at me askance, put a score on the target and told me to look at the board at the office and to keep in mind all the instructors were at the academy for one reason, to get on the pistol team.
So off I got, I forget, something around 20 instructors. If I had been on the board I would have been third or 4th.. Ahh hah.
Now, that was 38 wadcutters in an N Frame S&W so it was like shooting 22 after the 41 magnum full loads (it was my woods gun and I loaded those up as hot as they kept accuracy for - never wanted to shoot a bear but if I had to, well I was going to maximize the penetration.
Somewhat Ironic, my Step Dad had a card to shoot on base and he and I would go down there in the winter once in a while and shoot. He was better than I was. Not by a lot, about 55-45. He was all skill and I was just solid muscle.
