Distance and accuracy

Hello everyone,
I was at the shooting range about 2 weeks ago, shooting CCI Mini Mag 22lr 36gr (1260 FPS) ammo. I was shooting about 15-20 feet with a S/W M&P 22LR full size. At that distance, my shots were landing right on target.

I went back today and was shooting about twice the distance and noticed my shots were landing slightly left. I couldn't figure out why. But my question is, does distance affect ammo accuracy. I have proven that there's nothing wrong with my sights. Thanks in advance!

Hello again, folks,
I was thinking about the accuracy issue I had at the range today. Some of you may fall out of your seat laughing, but I had a band-aid on the first joint of my shooting finger today. When I was there a couple of weeks ago, there was no band-aid on it and those shot were right on target. I must admit, it didn't feel right; I mean, I could feel the trigger but because of the band-aid, the sensitivity wasn't there, and now that I had plenty of time to think about it, I believe because of the absence of sensitivity, my finger was not where it should have been on the trigger and therefore I was pulling the trigger incorrectly. I'm certain that is where the the issue was. But I will get back to you after I shoot again.

well, you wouldn't be the first to confess something like that.
But yes, an injury to the hand, even a small one can affect your shooting.

Me, I'm 76 now. My hands have good days and bad days. On a bad day, my hands might definitely pull my
shots off one way or another. And I've had to get used to this... It wasn't this way in the fairly recent past.
*shrugs... but the worst day shooting (or fishing) is better than the best day working.
That's a proverb.

For accuracy, you might want to try sub-sonic ammo. It's often held that as the bullet slows and transitions back through the sound barrier to subsonic, this can cause instability and loss of accuracy. Also, most .22 rimfire ammo will be closest to their labeled velocity when shot through a roughly 18 to 22 inch barrel. Shooting with a typical pistol barrel may still be supersonic, but not so far above it as the box suggests. Supersonic is roughly 1,100 fps at sea level - it varies with altitude and density. As you go higher, the speed of sound decreases.

Less wind drift with slower ammo too. Yeah, I know it's counter intuitive. At short range it might not be an issue, but if you start to reach out it should be.

The reason for poor results with hi v 22lr
has nothing to do with the transition from supersonic to sonic.
It has everything to do with poorly made cartridges.
It doesn't matter what the velocity is of the 22lr
when it's a collection of component and assembly problems.
Cr*ppy cartridges produce cr*ppy results.
It's that simple. :cautious:

Don't blame the transition for trajectory spread
when you already know that y'er using junk ammo.
