UltimateSlam 3-9x40mm

Leupold’s® all-new UltimateSlam™ riflescope is the ideal combination of flexibility, accuracy, and durability for today’s modern muzzleloaders and shotguns. As an example of accuracy, using Hornady SST 2-pellet, 3-pellet and 12 gauge shotgun loads at up to 300 yards, the maximum error of the UltimateSlam is less than 1" as compared to a 14" error from the leading competitor.

UltimateSlam 3-9x40mm is rated 4.9 out of 5 by 17.
Rated 5 out of 5 by from Unbelievable All I can say is NEAR ONE MOA AT 100 YARDS with 12 gauge sabot slugs CONSISTENTLY. With some good experimenting I figured out that with my set up and a 100 yard zero, I zoom out with the scope at 200 yards as the picture shows with the red dot on the dial to use the top of the post for shooting at 200 yards with the hold over. This is a mind blowing set up and people at the range can't believe I can group at 200 with it! See pics for reference. Equipment below. Info: - Leupold PRW Medium Rings (I could've gone with low rings) -Leupold Ultimate Slam 3-9x40 scope -Late 1970s Remington 870 Wingmaster - 12 gauge, Father's hand me down -Remington factory rifled barrel with cantilever mount (year 2010 or so, perfect fit) -Remington Accutip Sabot Slugs 2-3/4"

Rated 5 out of 5 by from Great value in a scope I purchased this to put on a Marlin 1894 44mag lever gun to be used for deer hunting. I didn't want a giant scope on my lever gun, and I don't plan on taking long shots, so this fit my needs wonderfully. I went with the heavy duplex and like how that looks when quickly pulling the gun up for a shot. The 75 yard parallax setting is perfect for the terrain I hunt in. The clarity of the scope is impressive, and I have found it to be very durable. Point of impact has not shifted since I did initial sighing in. I will defiantly look at Leupold for future optics needs.

Multicoat 4

Light reflecting off lens surfaces diminishes image quality. So Leupold® engineers developed Multicoat 4®, our own proprietary lens coating system to keep image quality pristine. 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. You’ll never be able to control the light, but with Leupold’s Multicoat 4, you can always make the most of it.

Generous Eyebox

The generous eyebox makes it faster and easier to get 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 pictue that fills the eyepiece completely - putting you in better position to make the shot of a lifetime.

BAS (Ballistic Aiming System)

Leupold’s® Ballistics Aiming System™ is comprised of five specialized reticles – Boone and Crockett® Big Game, Varmint Hunter’s, LR Duplex, LRV Duplex, and the new SA.B.R. reticles – which take into account the variables crucial to accurate, long-range shooting. A special ballistics indicator ring allows users to customize their power settings for their cartridge’s ballistics, then saves that setting for easy reference in a hunting situation. With multiple aiming points for longer ranges and varying wind speeds, and infinite power selector settings to match your rifle’s ballistics, the Ballistics Aiming System can help you master the art of accurate, long-range shooting. It has proved so successful in helping hunters learn how to shoot accurately at long range, we’ve expanded your BAS options with additional reticles offering many of the same benefits as the original reticles. We’ve also made them available in more riflescopes than ever. With practice, the Ballistics Aiming System will teach you how to gauge the distance to your target, where to place your reticle for that distance, and even how to compensate for wind deflection. With the Ballistics Aiming System and some practice, you’ll consistently make shots you wouldn’t have attempted in the past. Accurate, long-range shooting is probably one of the most difficult hunting skills to master. For many hunters, it remains a combination of hard-won experience, intuition, and a little luck. Together, the reticles of the Ballistics Aiming System give the hunter very useful tools for successful hunts with clean and efficient harvests. By practicing with the Ballistics Aiming System, all hunters can add science to the art of long-range shooting, and master this important skill. One System, Five Unique Reticles The Boone and Crockett Big Game reticle and the Varmint Hunter’s reticle use the same principles to help you hone your long-range shooting skills, though each has been tailored to meet the needs of big game or varmint hunters. With practice, using each will become a natural part of your shooting. Unlike other range estimating reticles, the calculations made here are incredibly simple, and take the guesswork out of long-range shooting. Each reticle provides a series of aiming points. The first aiming point, the intersection of the Duplex® reticle, is to be used at 200 yards with most common cartridges, and 300 yards with several flatter shooting, longer-range loads. The Boone and Crockett Big Game reticle and Varmint Hunter’s reticle also provides you with two different power selector ring settings, indicated by large and small triangles on the power selector. These allow you to select the hold points best suited to the cartridge you are using. In some cases, the smaller triangle setting can be used with your slower, heavier bullet load, and the large triangle setting with your faster loads in the same rifle. The new SA.B.R. reticle also features holdover points and a power selector matched to different load settings for muzzleloaders and shotguns. The LR Duplex and LRV Duplex reticles are designed to be used only at the maximum magnification settings. For example, a 30-06 with a 180gr spitzer bullet and 2700 fps muzzle velocity would use the smaller triangle setting. In the same rifle, a 150gr spitzer bullet with 3000 fps muzzle velocity would use the larger triangle. We have designated three sets of cartridges to be used with the large and small triangle settings, and sight-in distances of either 200 or 300 yards, described as Group A (large triangle, 200 yard zero), Group B (large triangle, 300 yard zero), or Group C (small triangle, 200 yard zero). Verify the aiming points by shooting at the actual distances at which the hold points in the reticle are intended to work. With the LR Duplex and LRV Duplex reticles a shooter can tailor the reticle to his or her load by varying the magnifications, thus altering the subtensions. With all four reticles, remember: practice, practice, practice!
