This allows for having a fixed aim point for 50, , , , and yards respectively see reticle image. They have also calibrated the magnification ring so there is no guess work in knowing what magnification setting will yield the correct spacing for your particular load.
To accomplish this, Leupold has replaced some of the commonly found numbers on the magnification ring with symbols representative of a typical muzzleloader or shotgun slug load.
Twelve-gauge shotguns are represented by a shotshell icon effectively 8x magnification which is calibrated for a gr saboted slug propelled at fps. Aside from the new S. The lenses share the same coatings; the objective bell, ocular bell and one-inch main tube share the same overall dimensions as the standard VX-I x40mm scopes, and I would venture to say the internal adjustment system would be the same as that found in the VX-I as well. Resolution was tested at a distance of 15 yards at the each scopes lowest magnification setting.
In terms of resolution, the Ultimate Slam was right in the ballpark with these other scopes, matching the Bushnell and being surpassed by both the Leupold VX-II and the Vortex Diamondback. In the field the results were pretty much the same with the Ultimate Slam and the Vortex running neck and neck, each having a slight edge under select conditions and slight inefficiencies under others. Offering 65 total minutes of both windage and elevation, the Ultimate Slam provides more than enough adjustment to get dialed in on most any firearm.
Eye relief is very generous at 4. Tracking with the Ultimate Slam was spot-on, and returned to the initial point-of-impact POI during the minute box test. The windage and elevations adjustments are the standard low-profile design with knurled finger-adjustable knobs. At the range I found the dot spacing of the S. Fortunately, because the reticle is on the second focal plane one can easily adjust the magnification ring to bring the aiming point and point-of-impact into alignment.
That in effect is the downside of calibrated ballistic-style reticles such as the S. As such, you will need to spend some time at the range with your preferred hunting load to find out where you need to set the magnification dial to match your load, or to determine how high or low your bullets print at the prescribed distances when set at the recommended magnification and log it into memory.
The Ultimate Slam is matched to three different hold point arrays contingent on where you stop the power ring: slug gun, two pellet, and three pellet. Depending on which Hornady data set you might be reading, the grain SST pushed by three pellets equates to fps at the muzzle with fps residual velocity at yards.
Based on the velocity at yards fps we have an approximate ballistic coefficient of 0. Here is our little conundrum. Based on these ballistics which vary significantly by individual gun and ambient conditions using the Maximum Point Blank Range method, assuming a six inch kill zone, zeroing 3 inches high at yards means a yard zero and a MPBR of yards. Phrased differently, a rifle with these ballistics means hold center of the body and pull the trigger out to yards with no adjustments.
The reason is not the wonderfully repeatable notion of gravity, but the problem of doping the wind as ranges increase. Just a 10 mph crosswind at yards moves the bullet nearly two feet, a calculated Our large diameter. There is no easy answer for this that I have to offer. So, back to the Leupold system, a rough approximation of this load based on a yard zero is. Inside yards, hit the switch. Whether you crank up the power to the appropriate setting and use the yard hold point or not, nothing can live on the difference.
From to yards is where this reticle is the most useful. Even at yards, we have approximately Beyond that, let your conscience be your guide.
Leupold has wisely noticed that dots can obscure your target at longer ranges, so the yard dot is commensurately smaller than the yard dot, something many scopes of this genre ignore. For from being a muzzleloader only scope or a slug gun only scope, the suitable applications for this scope are huge.
Multicoat 4 greatly increases the amount of all available light that reaches your eye, while at the same time, it minimizes the reflections of the sky on the outer eyepiece. This system delivers new levels of performance in every optical category. The result is razor sharp imaging across the typical light conditions experienced on any hunt—from the bright daylight of varmint to the dawn and dusk hours when big whitetails are on the move.
By repositioning optical elements, employing new coatings and importantly, leaving key, time-tested mechanical aspects of the Vari-X system untouched, significant performance gains have been achieved in many other areas as well.
The Quantum Optical System has greatly enhanced light transmission, resolution and color fidelity—all while preserving the ease of use and nearly indestructible ruggedness that has been a hallmark of Leupold rifle scopes for generations.
Generous Eyebox: The generous eyebox makes it faster and easier to set your eye behind the riflescope and achieve a full, clear sight picture.
Setting up for longer shots, you'll appreciate the flexibility it affords, and in close up big game or dangerous game situations, the quick target acquisition will be the difference maker. At high power, the longer eye relief and more generous eyebox gives you incredible head position latitude and an improved sight picture that fills the eyepiece completely - putting you in better position to make the shot of a lifetime.
