Blimey, thanks for that...i see now, once you drop the CF you use a different marking on the wheel..
Do you shoot with it down or do you get px error?
Think i will change to holdover once below 10 yds at the mo using a lower mag...or just px it at a lower mag as has been suggested, i have been setting rifle up on 50 mag down to 10yds'ish.
Also moved scope lower now so Rowan rail back up for sale soon!
All good fun, just need a nice day to set up!...some hope!
