February 27, 2022 – If you’re not using wind flags, you’re throwing away accuracy. There’s an inexpensive, simple device that can reduce your groups by half. This device is essential for accuracy. The “miracle device” we are referring to is a simple wind indicator, also known as “windflag”. The “miracle device” we are referring to is a simple wind indicator, also known as a windflag. You should always have a set of windflags or some other type of wind indicator with you when you go to the range or prairie dog fields, regardless of whether you are a competitive shooter or a varminter. You can cut down on group size by paying attention to your windflags. Here’s the proof: Miss a 5mph shift and you could DOUBLE your group size. The table below shows the effects of a crosswind of 5 mph at 100, 200, or 300 yards. You might be thinking, “Well, I’d never miss an 5 mph letoff.” Consider this: If a gentle 2.5-mph breeze shifts from 3 o’clock (R to L), to 9 o’clock (L to R), then you’ve just missed 5 mph net changes. What does that mean for your group? Take a look at the table to see what it will do for your group.
Point Blank Ballistics software for 500? elevation and 70? Temperature. Let’s say you have a 6mm rifle which shoots at half-MOA in no-wind conditions. What happens if you miss the 5 mph shift? This is equivalent to a full reversal in a 2.5 mph crosswind. If you shoot a 68gr flatbase round bullet, your shot will move approximately 0.49 meters. At 100 yards, your group size will almost double. The bullet moves 0.28 with a 105gr VLD. This is not as bad as it sounds, but enough to destroy a small group. An AR15 can shoot 55-grainers at 3300 feet per second. If you miss that 5 mph shift, your low BC bullet moves 0.68? This pushes a half inch group well beyond an inch. It’s worse than 1 MOA if you have a AR capable of shooting half-MOA. As you might expect, wind effects at 200 and 325 yards are even more dramatic. Your 300-yard range could expand by as much as 2.5 mph if you miss a full-value wind change of 5 mph. If you don’t have wind flags, your 300-yard group could expand by 2.5 mph if you miss a 5 mph full-value wind change. You can spend a ton of money on fancy shooting accessories (such as expensive front rests and spotting scopes) but, dollar for dollar, nothing will potentially improve your shooting as much as a good set of windflags, used religiously.Windflags Sources and OptionsWhich Windflag to buy?
