In a recent rifle pistol class at Pro Gun in Las Vegas, Carry Trainer ran students through a 100-yard prone group exercise — no bipod, no sandbags, just a red-dotted carbine and dirt — to verify the zeros they'd built the day before and tighten them up where the groups told the truth. The drill is simple on paper and brutal in practice: shoot a cold, unsupported group at 100 yards, then read what the holes are actually telling you. As Carry Trainer puts it, \"you get what you give.\" This guide walks through the methodology he taught on the line — how to shoot a diagnostic group, how to interpret flyers, how to calculate MOA at distance, and how to make precise optic adjustments that actually correct your point of impact instead of chasing it. Whether you're working a budget red dot or a precision bolt gun, the framework is the same. Group, read, adjust, verify. Key Takeaways Shoot diagnostic groups prone at 100 yards with no support — bipod and sandbags hide shooter error you need to see. Read the bulk of the group, not the flyer. Identify the cluster, mentally X-out outliers, then adjust to where most rounds landed. 1 MOA equals roughly 1 inch at 100 yards, so a 3.75-inch group at 100 is 3.75 MOA — and opens to roughly 10.5–11 inches at 300. Most red dots adjust at 1/…
