[Caliber 22]

For a while my rifle shot good groups from close by all the way to 100 meter and was at its best at 940 - 950 fps. This morning I opened a new tin and the shots was all over the target. At 50 meter it opened up to 25mm and even 30mm groups. I thought their was something wrong with the rifle. I took it to the 25 meter target and the groups was 12 - 15 mm. After some re-adjusting it settled down to 920 fps and did one hole groups again. I did try higher and lower speeds but groups where bigger.

I then checked the sticker on the tin and sure it was another batch, bought at the same time from the same dealer. All the other tins I received in the same parcel was another but all the same batch nr.

Just to show, always check for the batch nr when receiving and opening new tins.


5 Shots at 25 meter after adjusting. It started to rain so I could not test 50 meter and longer targets.

That's interesting, atleast thus far it's only been a matter of adjusting velocity. Hopefully the groups don't exponentially increase as you get farther or worse fall apart entirely.

Are you sorting your pellets?

Normally I do sort by head size but with this round I did not sort it. That one that went in stiff was a result of that.

I don't know if "stiff" is the correct word, English is not my home language. What will be a better word for it?

Stiff works, I normally say "tight fit" but I understood you just fine.
