This drill was discussed in @Tom Givens August 2023 Rangemaster Newsletter, and also in this recent thread
I think it deserves it's own thread. Here's the description, cut and pasted directly from Tom's newsletter.
"This drill really drives home the trigger management needed at different engagement speeds, driven by changes in distance. I think a reasonable goal here is 95% or better. Use a B8-C, an FBI-IP1, or the bullseye on an LTT-1 target. Try to keep everything inside the 10 ring under the time limits. All strings begin at The Ready, muzzle below the target, finger in register."
Stage 1- 2.5 yards: two rounds in one second
Stage 2 – 5 yards: two rounds in two seconds
Stage 3 – 10 yards: two rounds in three seconds; repeat for total of four rounds at 10 yards
Stage 4 – 20 yards: two rounds in four seconds
10 rounds total 100 points possible
I shot it yesterday and squeaked in with a 95, counting a line break. I dropped most of the points at 10 yards by shooting much faster than necessary.
It's a good drill, especially for those ranges that don't allow holster work.
