Today I got to compare my SWFA 1-6 with a Viper PST 2.5-10X32. I was very suprised by the results as they were the complete opposite of what I was expecting. I had both scopes set to 6X during testing.

It was an relatively bright day, with occasional clouds. I expected the PST to be brighter due to its larger objective, but that was not the case at all. The SWFA was noticeably more so and seems to show more vibrant colors as well. 

Resolution however, was another story. I've never been terribly impressed with the resolution of the SWFA 1-6. I can not spot .223 hits with it at 100 yards on orange or black targets. I can make out the general POI on white targets, but not very well. I had compared it once to my March F 3-24 on 6 power, and the March trounced it. I wasn't terribly concerned at the time because the March is a considerably more expensive optic with a 42mm objective. Today however, the PST had MUCH better resolution on 6X than the SWFA. I was surprised by this since the SWFA is the HD model. I guess it may have to do with the focus as the PST has an adjustable focus/parallax whereas the SWFA does not.

So in the end, I was surprised as the scopes performed the exact opposite of what I had expected. I figured the glass on the SWFA 1-6HD would be a little better at resolving and the PST brighter. Nope, not the case at all.

Has anyone else compared the two? Or surprised/not surprised by the results?

Be aware that most companies do not calibrate anything but top and bottom, so the March at 6X might not be 6X at all.


That said, I am surprised by not being able to see bullet holes at 100. I don't have the 6X but do have the 4X and have no such problem.


I have neither scope and am interested in others responses.

I have the 1-6 and bought my SIL the Vortex and installed and boresighted it for him.  I agree that the 1-6 has some issues with "fuzziness" not present in the Vortex, but the Vortex has some REAL tunnelling issues not present in the 1-6.  Though the 1-6 is useable at long ranges, that is not what I got it for.  It is on a 6.5Grendel with 14.5 inch barrel extended by the locked on flash suppressor.  6.5 Grendel is capable of much longer ranges, but I got it for the very close to 600 yard regime.  It is excellent there as is the 1-6.  The Vortex is on a Browning Stalker in 7mmRemMag.  To me, it is a "learner scope" for him.

That is somewhat odd.   I just finished testing a 2.5-10x32 Vortex and it did not have any tunneling to speak of.

I liked the scope a lot.

I thought I would... I did not...  the tunnelling was atrocious at low power.

It was in the ballpark. But whether it was a little above or below 6X, it still blew the SWFA out of the water, not even close. 

Even the difference between the PST and the 1-6 was concerning. Does anyone know where the focus/parallax of the 1-6 is set at?

So I ended up ordering a 2.5-10X32 and it came in yesterday. I was able to compare it to the SWFA and the March. None of them are mounted on rifles. Sad I was a very informal test at objects in the back yard. I only tested for resolution, didn't pay attention to CA and other issues.
 
At 6X, as before, I was able to resolve things the SWFA couldn't. At 100 yards, I could make out the texture of roof shingles better. At 300 yards, I could pick up individual pine needles more clearly.
 
At 10X the difference between the PST and March was quite pronounced. At 300 yards, I could tell with the March that the pine tree I was looking at (over the rooftops so I could only see the top of the trees) was actually two trees one in front of the other. Individual needles and pine cones were a lot more clear.
 
I do not expect an $800 scope to compare with a $2800 scope, so overall I am quite happy with the optics and design of the PST.
 
Unfortunately, build quality on the PST is another story. I have contacted Vortex about a potentially major issue, but even without that problem, it doesn't feel as solid as the other two. I am refraining from going into detail until I hear back from Vortex because it could be very minor.
