Rifle-specific details:

Official site: https://scsa.org/ · Researched 2026-10-11 · Confidence med. Rules change every season; the official rulebook always wins.

Tikka T1x

T1x fit

Legal in RFRO, but a bolt action is much slower than a semi-auto here. Treat it as fun or training, not a competitive choice.

CZ 457

457 fit

Same: legal but uncompetitive against semi-autos.

What it is

A speed-shooting match on fixed steel arrays. Rimfire rifle divisions are popular entry points.

Rimfire Rifle Optics (RFRO) allows scopes and red dots. Rimfire Rifle Irons (RFRI) is irons only. Any legal .22 LR rifle may be used.

Time-based: the fastest strings, summed across stages.
