My rifle used to shoot one hole groups at 25 meter and good groups at longer distances up to 100 meter. Now that was with a certain batch of pellets that is finished I don't get the same anymore. It still shoot one hole groups at 25 meter but it is split in two groups. It would shoot a few pellets through one hole, then the next few shots about 8mm higher and then back to the first hole again. The chronograph show the SD is about 5 -7 and ES about 18, but the high or low shots does not correlate to the speed.
It is a M22 in 5.5mm.
I checked and everything is tight. I tried another scope as well but it still do the same.
Does anybody has experience with such a problem? What would cause it?
