When i got my FX Maverick i was having problems, any sane person would have returned it.
The .177 rifle came set to 90 bar and hammer spring #7 where it shot 570 or so FPS with 13 grain pellets, and did so like a laser i might add.
BUT ! i did not get a blowpipe i got a high power airgun and of course wanted to sling my .177 lead faster, that was also possible and with a OK shot string, but now the gun was all over the place, with holes on 50 M changing 1" this way then 1" that way and anything in between.
Only pellet it would shoot fast was the 16 gr Beasts, those was like a laser at 50 M
I changed to a 700 mm barrel ( +100 mm ) when i could and this changed things, even if i have not shot all my pellets i do know the desired Monster redesigns i had problems with, they flew just fine now, and the slugs i now mainly shoot in the Maverick,,,,,, very enjoyable out to 100 M at least.
I am pretty sure someone shot my Maverick before i got it, and i doubt it was a Dane as i was at the shop hours after those rifles landed there for the first time.
But the first think i did comming home was cleaning it, and my patches said this rifle have been shot for damn sure. ( unless FX use crude oil / lead mix to preserve the barrels )
