How bad is the glass on SWFA 3-15

Has anybody encountered tracking issues with these scopes? I was just at the range.
Confirmed a 1/2” zero 5 shot group
Shot out to 900 yards prone
Dialed back down to 400 to practice some sitting/kneeling positions
Impacting left and low
Went to confirm on paper and shot a 1/2” 5 round group .7 down, .6 left
Never touched the windage the whole day
Recorrected the zero before leaving the range.

Any thoughts?

Um rings paint penned/torqued to 30 in/lbs
Base screws to 60 in/lbs

The gun never sprayed shots on paper. The 5 shot groups stayed consistently 1/2, just completely shifted low and left.
 
Been looking at the reviews on Mil-Quad reticles, SWFA in general, you name it...

Is there a big problem with the glass on the 3-15? It seems like there must be some catch that I'm missing, as it gets nowhere near the attention the 6X, 3-9, or 5-20 gets.

Anyone with input on what everyone else knows that apparently, I don't? 😂😂😂
I wouldn't trade an old Nikon monarch 3 3-12x42 for two SWFA 3-15x if I had to actually hunt with them. The SWFA doesn't trip my trigger.
 
A couple of S2H podcast episodes ago Jake said not all colors of paint pen are created equal, and UM now only uses certain colors. No joke! But he didn't say which ones are good and which to avoid.
 
So much for the paint pen is foolproof theory.


Who’s said that? And it wasn’t the paint that was the issue- bet money. It’s his cut away action and where he mounted the ring. “Paint” coming loose isn’t causing a screw to lossen up enough to shear a pin- nor is loctite…. But mounting the ring too far forward where the dovetail isn’t full depth will…

Not the first cut away action with busted pins either.


Here’s one, and if the recoil pin was used, it would have broke it too-

Actually, you've been the one saying that loctite has a failure rate and the paint pen doesn't. Others have chimed in too.

This seems much more likely to be the root cause. I have seen instances of non oil based paint pens being used that were worthless.

No doubt. We are seeing between 75-100 rifles used for at least 1,000 rounds each a year. 15’ish being used for 3,000 to 4,000 rounds a year. On average no matter how it’s applied, blue loctite is not setting up in about 5-10% of screws weeks to months after being applied. Paint pens- some are better than others (thicker); are about one out of 20 screws or less. To date, no screw using finger nail polish has still been wet weeks later, on any screw- though I’m sure there is some level of dilute too.
 
Maybe I didnt shake er up enough before applying? I been using isopropyl alcohol as a degreaser. Is there a better alternative?
I gotta say though. I tried my girlfriends finger nail polish before the paint pen and that was a disaster.
That being said, I am not trying to claim that my experiences should be considered . I am just trying to follow some of these protocols and have had some interesting results. Just sharing my process. I think not all nail polish is created equal.

I had full depth on the dove tail. Used the forwardmost screw in pin and the first mounting hole in the rings.
