Scope minimum range.

[kb1]

I have just purchase and fitted a RICHTER optic 3-9X40mm scope on to my Gamo Magnum 3000.
Can scopes like this have clear focusing at a range of 45-65 feet?
This one doesn’t even at zooms between x3-x6. However if you pivoted the rifle and scope on any axes so the target moved towards the edge of the field of view the target comes sharply into focus.
I have turned the eyepiece but it doesn’t make a lot of difference and turning it to much make you see double cross hairs!
The shop sent another one out to me and that is out of focus all over the field of view!
Is it the scope type? Manufactures quality control? Or do I need to spend a lot more that £35?

The scope sounds like it's parallax focused to 100 Yds for rim fire etc.

It sounds like you need to re-parallax the scope. In other words wind out the objective lense until the scope is parallax focused at 30 Yds. You should then see that at x9 mag that everything is in focus from about 40 yds back to about 10 or 15 Yds depending on the scope.

You can find more comprehensive instructions on how to re-parallax a scope if you do a search on this site.

Before you do anything this is a new scope so check with the shop you bought it at to find out where the parallax is set to, it might tell you in the instructions. If you don't feel confident about doing it don't swap the scope for one that is parallax set for an air reifle at 30 yds. But it's going to cost a little more. I would look at the AGS air rifle scopes or maybe one of the Hawks if thats what you decide to do.

Thanks done that unscrewed the object lens end ring unscrewed the unit holding the object lens about 4 turns and replaced the end ring using a blunted cocktail stick (just in case I slipped) to keep the lens mount in place and its crystal clear now at 65 feet (22 Yds) . OK at X9 it’s a tad out of focus at large dissentiences but Squirrels don’t bother me at large dissentiences so it’s not an issue.
