After reading through a few posts on here regarding scopes for rimfires, I decided to share a test of limited value and scientific method, although I hope it may still be helpful. Coming up to dusk, I set up a zeroing target of ¼” black squares on a white background and placed it 25 yards away against a dark wooden wall. Also at 25 yards I placed a white, gray and brown silhouette target of a rabbit partially in deep shadow, and egg on top of a post in full day/moonlight and a shiny bottletop in full shade. There was some small amount of constant and consistent artificial light.
The times given are the point at which the black squares could not be aimed at reliably.
3-9x40 were set on 6x, the Falcon on 8x.
Nikko –Sterling Gold Crown 6x40 20:21
Weaver 4 x 38 20:10
Hawke Panorama I/R 3-9x40 20:16
Falcon Menace 4.5-18x56 20:22
Edgar Brothers Silver 3-9x40 20:20
Redfield 3-9x40 20:22
The times that the silhouette became unshootable.
Nikko –Sterling Gold Crown 6x40 20:35
Weaver 4 x 38 20:30
Hawke Panorama I/R 3-9x40 Some time after 20:45
Falcon Menace 4.5-18x56 20:30
Edgar Brothers 3-9x40 20:35
Redfield 3-9x40 20:35
As noted the results were almost reversed. The limit on shooting was down to the reticle disappearing, although the Weaver just blacked out in parts of the picture due to lack of light. The illuminated Hawke, was still usable right up until complete darkness on the egg and silhouette.
The Gold Crown, E-B and Weaver were all less than £30 secondhand.
The Menace was £140 very nearly new.
Hawke was £70 old stock, now £135 at Uttings.
Redfield Revolution £205.00.
All the above hold zero very well on rimfires and tuned springers, the Redfield and Weaver are just zero and forget even on centrefires.
All were capable of extending shooting time on the zeroing squares beyond the time that they could be seen with the naked eye. All were capable of showing the silhouette beyond the time that they could be seen with the naked eye.
I was wondering what to fit to my HMR, having become annoyed at the poor twilight hunting range of the Falcon being worse than the (broken) Hawke Varmint IR it replaced.
