Speed Option is the stage that punishes a bad plan, and it is the only stage in Steel Challenge where the stop plate is a rectangle instead of a round plate — sitting 105 feet away, over on the far left. That single fact rewrites how the whole stage should be shot.

The official layout

Four 12-inch plates and one 18″×24″ rectangular stop plate. One 3′×3′ box. Five strings, best four counted.

Our own scale plan of SC-107 · Speed Option, drawn from the dimensions published in Appendix B of the SCSA Competition Rules, edition 2026-03. Distances are measured from the shooting box; offsets are from the center line; heights are to the top of the target.

The stop plate is the stage

On seven of the eight stages the stop plate is close, round and easy, and the plan is simply to finish near it. Here it is a rectangle at 105 feet — 35 yards — and 21 feet 6 inches to the left of the box. It ties Outer Limits for the longest target in the sport.

That means the usual advice to finish the array near the stop plate is not enough. You want to finish the array on the left side, because your last transition is going to be a long one no matter what and you would rather it be short in angle even if it is long in distance.

The layout, in plain terms

Two plates on the right: one at 24 feet just 6 feet 6 inches off center, and one way out at 45 feet, 21 feet to the right. Two plates on the left: one at 30 feet, 12 feet off center, and one at 60 feet, 6 feet off center. Then the stop plate, far left and far away.

Notice the asymmetry: the right side has the widest standard plate, the left side has the deepest one, and the left side is where the run has to end.

How to shoot it

  • Start right, finish left, then the stop plate. Near-right at 24 feet, far-right at 45 feet, then cross to the left pair, then the rectangle. That leaves you already pointed left when the last standard plate falls.
  • Take the 105-foot rectangle seriously. An 18-by-24-inch target at 35 yards is a real shot, and the whole string rides on it — miss it entirely and that string is 30 seconds under rule 9.4.
  • Do not rush the settle before it. A quarter second of stillness before the last shot is the best-spent time on the stage.
  • Know the sight offset. If your dot or scope is zeroed at 25 yards, at 35 yards it is close enough not to matter on a target this size. If you are running irons at a 10-yard zero on a rimfire, it is not.

The common mistakes

  • Shooting left to right. It ends the array on the right and asks for a 40-plus-foot lateral swing to the stop plate, at 35 yards, as the final act.
  • Treating the stop plate like every other stop plate. It is the hardest target on the stage by a distance. Plan the run around it.
  • Firing an insurance round at it. The timer stops on the last shot fired, not on the hit (9.2.2). A second shot at 105 feet is expensive.
