Hi all,
Been laying down some groups today. It's cold, but clear. Not too windy.
The bottom target, I shot first; 5 shots in 1/3" @ 15 yards. They grouped up and left. I corrected 2 MOA down and 1 MOA right and then shot the top target.
Everything started off well; one right in the bull. From there, they drifted down and right more and more. Once I had the third shot in a row land outside the 4 MOA ring, I stopped for a bit.
If I take slow, careful shots, they seem to group well; 5 shots in 1/3" at 15 yards. But if I lay down 10 or 15 in a row, they tend to track down and right.
In other words, the longer I shoot, the more fliers I tend to get.
Should I leave my rifle to acclimate to the cold for a bit? What about time between (springer) shots?
What about the pellets? Let them get cold? Keep them warm?
Thanks all.

I think the term "flier" relates to the situation where you have a stable zero and you get unexpected outlier shots. Groups tracking down and right as you note don't seem to be fliers as much as they are a change in POI. Why that is happening is probably related to the spring and rifle warming as you handle, cock, and fire it. Not something I have any experience with since I don't generally shoot unless it is warm enough for comfort. Just my guess.

Benjamin Prowler Nitro Piston .22. The rifle has been outside for several hours now, so it should be pretty stable.
Maybe I should give it a few minutes between shots and see if the groups tighten.

I saw (springer) in your above post. Shooting/cocking has to generate some heat even if the rifle has been outside. Not sure how a gas piston responds but compression generally is going to generate heat. Interesting problem to watch.

Before you assign the change in POI to the rifle, somehow you need to eliminate shooter influence. Could all be the shooter. Could be the cold infuencing the shooter.
Could even be a change in hold, change in clothing because of the cold. Loss of concentration.

Certainly possible. But I bet most shooters would certainly try to control that.
