On Sunday this week, Sept. 29, I shot fifteen ten-shot groups at 100 yards with a good lot of Center X. One of them was the best I've had the pleasure of seeing first hand. The caliper shows the outside-to-outside measurement.

Of course not all groups were like this one. The fifteen group average was under 0.930" center-to-center.



Yesterday, Oct. 2, I used a different rifle and a different ammo at the same distance. I shot ten ten-shot groups and had the pleasant surprise to see two of the ten looking nice. Again, the caliper shows the outside-to-outside dimensions.

Again, not all groups were equally good, but the ten group average was under 0.850" center-to-center.

Those are truly excellent, beautiful rifles also! Good shooting without question. I am curious what the wind was doing, & what were the rest of the environmental doing?

Thanks again.

For readers in general, the most important environmental is always wind, especially as distance to target lengthens. As noted earlier, along with ammo all depends on when to shoot. If wind isn't accounted for at 100 yards, shooting well is not possible.

I find reading wind flags at 100 yards is more than twice the challenge it is at half the distance. My club range is a small one with a lake only yards away on one end, with hills and trees elsewhere. When there's wind it is usually switchy, with flags showing different directions and wind strengths. Those conditions can be difficult to interpret.

I always use wind flags and they can help confirm calm conditions, which is my most productive time to shoot. The best chances for calm are generally early in the morning and on a few occasions it may continue for a few hours.

👆 Truth...

To illustrate the point a 1 mph (as measured with a Kestrel) full value (90⁰ from the bullets path of travel) will move a 40g match bullet going 1060-1070 fps @ the muzzle roughly 1/2 of bullet diameter at 50 yards. I have tested and proven this many many times.

Think about that for a minute. It's a wind that is barely noticable in everyday life.
