Today we take a closer look at the new Meopta MeoSport R 3-15X50 SFP scope. It’s been awhile, but now this scope is stocked by Pyramyd Air and you guys and gals can get one if you like. I first told you about this scope in Day One of the 2022 SHOT Show report. Here is what I said then:
“This is an entry-level scope for those who want a Meopta but don’t want to pay great big bucks. Unfortunately they can’t just give it away, either. So it’s priced at a retail of $450. It has a 30mm tube for a bright image. But here is the deal. It isn’t just the scope, it also comes with the mounts. And the mounts are kinda special.”
The SFP stands for second focal plane, which means it’s like all other variable-powered scopes whose reticle lines don’t enlarge as the power changes.
This is also the scope that has lines engraved on the bottom of the 30mm tube and also on the rings that come with it, so you can level the scope easily. I talked you through that in Part One. That is what I meant by the mounts being “kinda special.”
Today’s test — boxing
What I want to do today is test the accuracy of the reticle adjustments by “boxing” the reticle. What I mean by that is I will shoot a 5-shot group at 25 yards, then adjust the scope a certain number of clicks in a certain direction. I will go 12 clicks to the right. Then I will shoot a second 5 shots at the same target. That group should move to the right of the first group. Then I’ll adjust the same number of clicks (12) down and shoot a third 5-shot group. Then I’ll come back the same number of clicks in the opposite direction (left 12 clicks) and shoot another group. That will be four groups and, if this scope has precise adjustments, the centers of those groups should form the corners of a box.
For the last group of five I will adjust up 12 clicks and shoot at the same target. We should see a box of four groups, with the first one being slightly larger since it now has ten shots instead of five. I know the Avenger Bullpup .25 that the scope is mounted on does best with JSB Exact King Heavy Mark II pellets, so that’s what I’ll use. Here we go.
I had to sight in the rifle to group away from the center of the bullseye. I won’t just be shooting a group of five or ten shots. I’ll be shooting 25 shots by the time this is finished — 5 above the center of the bull, five to the right, five below that, five to the left of that and the last five on top of the first group.
I’m not trying to confuse you but until you see this on paper it might not make any sense. Here are the first 4 groups I shot. I will explain what I did after showing the picture.
The first group at the top left is above the center of the bull and measures about 0.30-inches or less between centers. I didn’t measure it with calipers, so that’s just my estimate. Remember, I’m shooting .25-caliber pellets so all these groups look larger. After shooting the group I adjusted the scope 12 clicks to the right.
The second group is to the right of the first one. The first two pellets didn’t go all the way over, which is why this group is larger. That’s from stiction. After that the shots grouped together. This group measures 0.617-inches between centers.
Next I dialed 12 clicks of down adjustment and shot the third group. This one measures 0.406-inches between centers.
For the fourth group I dialed in 12 clicks of left adjustment. There was a little stiction on the first two shots, then on shot three the group came over to be in line with the top group. This group measures 0.349-inches between centers.
Discussion and group 5
I took the picture shown above because I figured the first/last group would grow in size. It did for two reasons. First it grew because ten shots will almost always be larger than five shots. And second because if I pulled a shot, I might throw it wide of the main group. In the first 20 shots there were no called pulls.
The first two shots of the fifth group didn’t enlarge the group at all. But the third shot of the final five was called high. It is the highest hole seen in the next picture. By the time I finished this group a total of 32 shots had been fired.
Meopta reticle adjustments are precise
With some scopes you feel the clicks as the scope is adjusted. With other scopes you also hear them. With cheap scopes you may neither see nor hear anything and you have to watch an adjustment line on the scope knob relative to a scale. This Meopta scope has silent clicks that are easily felt. Pull up on the adjustment ring to unlock it and then feel as each click changes. When you are finished push that outer ring down and the adjustment is locked.
I used to get so angry at airgun shows when guys would pick up my rifles on my table and start turning the knobs just to feel the clicks! For some reason they thought that was alright. What if I jumped in the driver’s seat of their car and adjusted the seat and armrests? That probably wouldn’t be alright, would it?
Think today’s test is easy? Try it. It is embarrassingly difficult, and it reveals many of the hidden flaws of a scope. Remember, you have to hold perfectly for every shot. It’s like shooting a 25-shot group.
Only a quality scope will give results like you see here, and that is the reason for this test. First, does the scope adjust as you think it should? In other words, is every adjustment with the same number of clicks moving the same distance? And with four adjustments like these will the groups be shaped like a box?
Second, does the scope return to the starting place at the end? Can you put the fifth group on top of the first group?
This test also shows the tendency for stiction. I see now that this particular scope has some stiction when adjusting left and right but not when adjusting up and down. That doesn’t mean that another of this same model scope would act the same. This is something unique to each scope and has to be evaluated by the user, or suffer the heartache of never being sure when you are zeroed.
Cheap scopes will show their colors when tested like this, but it is essential the rifle that’s used to test them is one of known accuracy. The air rifle becomes the testbed for the scope.
Bipod test will be next
I said at the end of Part Five of the Avenger Bullpup report that the next test would be shooting off a bipod, but since today’s test scope is mounted on this rifle I did this test instead. I didn’t want to test two different variables at the same time.
Before you criticize anything you see today please try this test yourself. It has been years since I did one of these, but since the Meopta MeoSport R 3-15X50 SFP scope is being tested is a top end scope I felt it needed an acid test. I can now recommend this scope to anyone who is comfortable with the 3-15 power it offers. Remember, Meopta doesn’t recommend this scope for use on a spring rifle, though I am testing another Meopta scope on my TX200.
I had fun today and I’m inspired to try this test again with another air rifle of known accuracy and another fine scope. Maybe my recently tuned TX200 MarkIII that also has a Meopta Optika5 mounted?
