Follow-through
Follow-through is staying in the shot through and after the break: keep your position, your cheek weld, your grip, and your trigger press held for a beat after the rifle fires. The bullet is still in the barrel for a measurable instant — any disturbance during that time moves your impact.
Practically: after the shot breaks, keep the trigger pinned to the rear, recover the recoil straight back into your shoulder, and re-acquire the reticle on target. You should be able to settle the reticle right back where it was.
Calling your shot
A called shot is your honest prediction of where the round went, based on where the reticle was the instant the shot broke. If you have good follow-through and a clear sight picture at the break, you'll know: 'that one broke low-left.'
This is the master skill. When your call matches the actual impact, you're in control of the rifle. When the impact surprises you, something in your fundamentals broke down (usually trigger or follow-through). Calling the shot tells you whether to trust a group or throw out a flyer as shooter error.
Building the loop
Every shot is a feedback loop: position → NPA → breathe → aim → press → follow-through → CALL → check actual impact → adjust. Logging your groups (which this app makes easy) closes that loop over time so you can see real improvement, not just feelings.
