Title: Info on Scope, parallax matter
Post by: kar120c on March 19, 2017, 09:26:23 AM
Thinking to buy a scope for my 1377, I am looking at this price target http://www.gmaccustomparts.com/epages/BT3197.sf/en_GB/?ObjectPath=/Shops/BT3197/Products/400-003
I see that the most of these scopes are declared parallax error free at 35y.
My 1377 is detuned to be free in my country but it shots around 500 fps. Its the ideal shoting range go from 10m to 20m (yards is almost the same).
Can I use one of these scopes from 10m to 20/30m distance with accuracy?

I would think you probably could use that scope.  There is a way to change the parallax that works on most scopes.

The CenterPoint scope has a 20 yard parallax.  http://www.pyramydair.com/s/a/CenterPoint_Adventure_Class_2x20_Pistol_Scope_Duplex_Reticle_1_Tube_Weaver_Rings/4297
I have a problem using a pistol scope because, free hand, I cant hold the gun steady enough and the bouncing crosshairs are a distraction.  I seem to have better shooting using a Millett SP-1 red dot scope.  Having a 3mm dot size it doesn't cover too much of the target as the 5mm dot size.

I use this one. Right in the same price range as the GMAC scope. But, as Bill said, adding a scope to a pistol makes for new challenges due to the added weight. I pretty much bench rest so I am good, but I have shot this scope on my 1740 offhand. It is possible. If you are young and strong.....no problem!  I'm old and weak ;-)

I do have an old Beeman scope and the parallex has been adjusted a little but anything in the 10-20 meter range is fuzzy and does not make shooting very enjoyable. I can shoot pretty good groups with it, but a scope with clear optics is head over heels better.

Parallax can be (mostly is) a problem with airguns and shooting a short distances.   If you can adjust the parallax to the most common and useful distance, it is a good solution.

But with varying distances an AO (front or side adjust) is really the most satisfactory solution and all that I use.   Many are reasonably priced.

Me too...I use a UTG 3-9x32 AO "Bugbuster" and a UTG 4x32 AO "Bugbuster" on pistols I want to scope.  Paralllax adjustable from 3 yards to infinity.  Although it's a rifle scope it works very well using a "taco hold" for offhand shooting.  Works off bags on the bench just as well.

2nd the bug buster! It will focus from 3 yds to farther than you can shoot.
