3-10X 40mm Grand Slam
As I said before, the Grand Slam is Weaver's top-of-the-line model, and it is the company's idea of what a top-quality hunting scope should be. I chose the 3-10X 40mm model for review because I thought it would be ideal for most big-game hunting situations.

Removing it from its box I found an attractive scope with very nicely proportioned lines that gave it a well-balanced look. Length is a relatively compact 11.8 inches, and weight is a fairly light 13 ounces. Attractively knurled caps cover nicely designed finger-adjustable turrets. These are easy to read and provide 12 MOA of adjustment per full turret revolution in audible and tactile 1/4 MOA clicks. Weaver's patented Micro-Trac adjustment system is utilized, and this model features 70 MOA of total adjustment.

One feature I liked is Weaver's SureGrip power ring. It is comfortable to the touch, even in extreme cold. In addition it's contoured so that the magnification settings are visible at 9 o'clock while looking through the scope. This allows a right eye dominant sportsman to easily view the magnification settings with his left eye without having to lift his head and peer at the top of the scope. It's a nice touch.

The Grand Slam (as well as the T-24) features fully multicoated lenses. Field of view (FOV) runs from 35 to 11.3 feet at 100 yards. An adjustable diopter is fitted, and eye relief runs from 3.5 to 3.0 inches. This model generates a 12.6mm exit pupil at 3X, which shrinks to 4mm at 10X.

Optical performance was quite good with the Grand Slam, impressing me with a very bright image, accurate color rendition, and very good resolution. The image is flat and clean to the very edges at 3X. Even at 10X resolution is very good--almost, but not quite, to the outer edges. While many scopes have a problem to some degree with internal flare, the Grand Slam seemed to ignore piercing counter-light. Optically, the Grand Slam performed very well and bested the T-24 in this regard.

Mounted onto a rifle, the Grand Slam zeroed without incident and easily passed a box test. I also noted point of impact was unaffected by changes in magnification.

My thoughts? While no longer American made (both the Grand Slam and T-24 are made in Japan), Weaver's 3-10X 40mm Grand Slam impressed me. Optical performance was very good, and I really liked the finger-adjustable turrets and SureGrip power ring. I would expect the Grand Slam to make a fine hunting partner. Suggested retail price is $429.99.

24X 40mm T-24
Weaver first introduced the T-Series of fixed magnification target/varmint scopes in 1977. Designed for benchrest and metallic silhouette competitors and varmint hunters, the T-Series introduced Weaver's now justly famous Micro-Trac adjusting system. Not just a marketing gimmick, the Micro-Trac system has proved to be an extremely reliable adjusting system over decades of use in competition. This feature quickly earned the T-Series an enviable reputation for consistent and repeatable adjustments. In doing so it became quite popular in benchrest competition.
