AEA AEA SF .25 REG TUNING PROBLEM 2025

I HAVE A AEA SF COMPACT .25 I CANT GET IT TO SHOOT ACCURATE I HAVE TRIED JSB KING KINH HEAVY AND HADES IT SHOOTS ACCURATE FOR LIKE 20 SHOTS AND FILL IT BACK UP AND IT SHOOTS HORRIBLE AGAIN
I have an sf 30 compact, and I have no trouble with aea pellets, but I run hades too. I run it around 175 bar shooting 700 fps. I'm surprised you are having trouble with jsb? The weight tolerance of the aea pellets may be better than jsb. It is only a 10 inch barrel under the shroud. Mine is zeroed at 35 yards. I would try a can of aea center punch pellets

Ive had it for year and it has a 10 inch barrel i didn’t have a problem with that for a while and lately i it just keeps doing it and before i was shooting 25 grain jsb king and now it doesn’t shoot good with that ammo
