Own several of the Weaver Super Slams, one is the 3-15x42 and other two are 4-20x50. Mind you, bought them several years ago, so they are the older design Super Slams. Think Weaver redid the line of Super Slams in the past year, so I do not own one of the new versions of the scope. Light Optics Works (aka LOW) of Japan, who also happens to make high end scopes for Sightron, Bushnell and others, make the Weaver SS. Anyway, mine are LOW made too.
1. As mentioned already, you should be happy with Super Slams optics....quite clear and bright.
2. Good tracking and feel of their pull-up turret adjustments, and it's parallax adjustment for mine seem to be spot on with its distance markings.
Recall the day a fellow range member showed up with a new hunting rifle (for elk) with also a new Zeiss Conquest in the same power range and 42mm lens as my 3-15. He buys some nice glass for his rifles. Would have him sit down with my Weaver scoped 3-15x42 rifle and give me his opinion of how my Weaver compared to his Zeiss. Long story short, after around 5 minutes playing with my scope, viewing down range, he noted no difference between the two as far as quality of glass, adjustments and etc. Commented he liked the Weaver Dual-X reticle over whatever reticle he had in his Conquest. He was surprised by how much less I'd paid for my Weaver.
What's negative to me about my Weavers. Yep, not a scope for a light build carry rifle...definitely on the heavy "beefy" side. A shooter in Australia commented why he bought a Weaver was based on an old friend's opinion on what brand scope to buy. Guy asked, actually worked in a scope repair shop doing factory warranty work/repair for various popular scope brands in their country...."buy the Weaver Super Slam, its internals are built like a tank." Guess this helps explain the extra weight of a Weaver SS.
Also, you'll find the spacing for rings on a Super Slam scope tube kinda short. This is especially true for Savage long actions. I needed extension rings or a different scope mount (had two piece Weaver mounts on rifle) in order to install one of my Weavers on a Savage action.
I've had my Weavers on a fair number of different rifles, with lots of rounds fire with them at range. Generally, with a newly acquired rifle, one of my Weavers goes on it when I'm testing the rifle for accuracy or working on accurate load for it. Have not noted any critical eye relief problems, centering of eye and etc., and I certainly trust the turret adjustments on mine.
