setting up open sights
i have a cometa fenix 400 with open fibre optic sights, the front sight is fixed but the rear will adjust on a circular dial marked from 0-9. Which number roughly corresponds to what distance? eg if i'm shooting at 20 yards? i've no idea!
you would probably be better just using paper with a steady rest and setting up from there.... instead of paying attention to the numbers on the rear sight adjustment.
As already stated the only reliable way is to ignore the numbers,put out a paper sheet with a dot in the centre and start shooting.Move the sights in the direction you need the pellet to go just like telescopics.And always aim at the dotevery time,you should have the dot looking as if it is sitting on the front sight post.Use a sandbag or a rolled up towel under your support hand and just rest the forestock in your palm.Also make sure the pellets actually suite the barrel as there is no point in trying to zero a gun with pellets that fly all over the target.Not trying to tell granny how to suck eggs or anything just stating facts and observations from watching people trip over the littlest things.Good Luck with it as it is an accurate gun and will repay the effort.
My Mrs had a Cometa 220 in .22, 16 quid as it was shopsoiled???
This had open or iron sights, they were the fibre optic type, two green dots on the rear sight and a red dot on the fore sight, It/She was deadly with it,
Play with the rear sight screws and see what action does what so you know which way to go,
Place a paper target out at ten yards and with the airgun rested on a rolled gunslip or whatever, shoot three to five pellets at the same point on the target,
Do not grip the gun, relax and let the gun fall naturally on the aiming point and gently SQUEEZE off your shots,
This will produce a group of pellets and should show where the gun is hitting,
For iron/open sights the rules are simple,
UP= the rear sight needs to be raised,
IE: Shoot low, raise the sight,
Pellets fall left = Move the rear sight blade to the right,
At ten yards set the left to right until shots are centre and a little high,
Move out to twenty yards and re-set left to right, should be set to a little high,
30 yards which is about maximum for open sights,
Set sights for dead centre hits,
Happy and Safe Shooting.
Sorry can't really help J4M3S but i've recently bought a springer with fibre optic sights and i've not adjusted them and it shoots spot on! that normal?
i'm going to buy a scope
that sorts everything then mate, far more accurate, plus gives you further range
