Hello to all dear member,
i come to you concerning a friend of mine owner of a beautifull Crowm laminate .25 . He use Jsb king heavy MK2 and king standard
from 0 to 50 m accuracy is good no sign of spiralling the pellet fly correctly, past this distance the shoot group start to move on the left, strangely all pellets spiraling in the same way.
the group move on the left side of the target, we use slow motion to confirm spiralling and effectivly we see perfectly the strange behavior.
we have tested from 245 to 266 m/s and the result is same.
i already have the same problem with my Impact and for me the solution is:
Opened transfert port to 6mm, polished breech, polished barrel, opened shroud exit,
i have applied the same routine on the Crown but with no success.
In any case, thank you for reading my poor english
have a nice day to all
Thierry
