My eyes are hurting

I have a Hawke Sidewinder 5-24x56 FFP that is truly fantastic on three of my rifles. With the red/green IR and 20 yard parallax, I don’t think you could go wrong.

Good luck!

I also have a Hawke Sidewinder 6x24x50 FFP on my Wildcat and have been impressed with it. Would buy another one for sure.

Might be a stupid question but have you tried "splatter burst" type paper targets? I can easily see poi with my SFP scopes & I turn 68 in 10 days so I relate to the "old eyes" thing. I make my own targets of this type also. A LOT cheaper than a new scope! 

How about using a splat type target that shows yellow over the black back ground 

I would think a spotting scope next to you would be a way to see your hits 60X will give you great visibility

you can get a B&L Discoverer on Ebay at great prices used but maybe I missed your point 

You don't need a new scope, you need a new, larger caliber air rifle !

I have a like new Hawke Sidewinder 6-24x56 ffp red&green illuminated retical I’ll sell you for $400 shipped. Worked great on my 72 year old eyes, sold rifle.

Don't know how you get by with a 18X scope. I'll be 70 in July and I pulled a 16X scope out the other day and could barely see the target, let alone the pellet holes. I moved up to a cheap 6-24x50 Discovery scope for about $300 and have no problem seeing my holes at 80 to 100 yards. I also have a 8-32x56 Hawke and it is one of the clearest scopes I have ever used … but for some strange reason I usually shoot the guns with cheap Discovery scopes on them … they just seem to get the job done pretty good and visibility is no longer a problem. It's a pain getting older, but it beats the alternative. 

Another thing about Hawke is their lifetime warrantee. I have the airmax 6-24x50 and I see 100 yards pellet holes in paper no problem. No spring chicken here either.

I have an Aztec 5.5-25x50 and can see my .25 holes at 100+ yards most of the time. It has a wonderful reticle. Parallax to 10 yards no IR. 400-$500 Also have a 45 power spotting scope for the days I can't see much of anything. 

Lighting can play a huge part in seeing your impact points 

a cheap trick go to harbor freight and get a solar flag spot light put your target on one of those plastic signs with the light shining up from the ground behind the target

I just use a piece of black tape to cover the light sensor so the light comes on in daylight takes a little adjusting but my holes are easy to see and when done right it doesn’t wash my target out

also plays double duty I can move it to the front and shoot at night when I want too

Besides the splatter burst targets I too have a Hawke 6x24x56 through which I view them. No spotting scope needed. 

I'll be happy to send you some targets to try. Those "China deliveries" can be slow! PM me if you want some. 

Buy your splatterburst targets at amazon, next day or two delivery.

Time to step up to an airforce Texan in .458 Cal. You won't have any trouble seeing those big holes.
