My Fellow CZ Lovers:
One of the things that strongly attracted me to both the CZ 452 Lux and to the Ultra Lux was the high quality and utility of their factory tangent sights. The Lux once thoroughly cleaned gave me easy windage adjustment then with the elevation of the rear sight set at 25, as low as it could be set, gave me little bee shaped groups dead center with Lapua Master L +.001 diameter .22 LR, which I had on hand at considerable expense of $9.00 the 50 rd box. Up to the next distance 50 yards was the next notch up. The setting for 100 yards with this match load was about the 100 yard notch. and hit center on a ground squirrel target in ca. 1". As yet I had not checked how the moveable front sight was set, only determined, when cleaning, that it was moveable and seen this in a downloaded CZ 452 Lux manual.
I next fired Federal Gold Medal and found I had to lower my rear sight a little to hit center on the little ground squirrel target Accuracy was very good but not up to the Lapua Standard. Federal also hit a little higher at 25 and 50 yards, but not enough to make anything but a slightly lower hold necessary for close range field use.
I got surprised when I went to a different class of ammo, the hyper velocity CCI Velocitor, which was the fastest 40 grain bullet load at that time. It hit 8" above the setting for the match rounds at 100 yards on clean target paper above my ground squirrel in 1". I was getting a demonstration that from the bench in quiet air my 1999 CZ Lux with its match chamber and bore was extremely accurate with its tangent sights, even with a hyper velocity hunting load. I knew that the CCI Velocitor could be accurate to 300 meters from my Savage Stevens Favorites by my methods, so I was very interested in what it would do from the CZ Lux to the maximum distance listed 200(yards or meters).
Given that it was hitting 8" high at 100 yards, I raised the rear sight to 150 and aimed at 6:00 at a 200 yard black powder target a friend had posted at 200 meters. It hit repeatedly in 3.5"-4" just above point of aim. I considered that both remarkable and proportionate to the very fine results I was getting using tangent sights with the little Savage Stevens "Crackshot" Favorite and the Model 30 G half octagonal.
I went hunting using Federal Gold Medal and had little trouble quickly estimating the ranges to squirrels or knowing these from previously pacing them off from a waiting spot. It proved easy to quickly score a lengthy record of close range head-shots on the limb-chickens from supported positions to 100 yards.
I can say much the same for the Ultra Lux. The tangent sights, when the front sight was set at lowest possible screw purchase on the Lux allowed me to easily change sight settings with the lower velocity match and small game loads. I did not change that front sight setting for years on the Lux, until I tested the Williams FP receiver sight with target knobs on the rifle and had to bring the front sight up and remove the rear sight leaf. Then I tested a 3-12X 30mm tube 50 mm scope on it, and afterward gladly returned to the tangent sights.
It took me a little shooting on Feb. 2, with the Lux to find that I must return the front sight to lowest full screw purchase on my Lux's front sight to regain the match ammo center grouping at 25 yards on 50 ft small-bore targets with the low 25 yard rear sight setting using this time the tolerable Aguila Golden Eagle Match Rifle, which shot very well, giving some bee sized center groups. By the time I confirmed the 50 yard elevation on the Lux, the sun was hitting my rear sight. This does not happen with receiver sights or scopes. It changed my optical perception of the rear sight, the first time this has happened in 63 years. This really put me off my game. I saw well enough for elevations, though the sin-lit sight ruined my windage a bit. Aguila GE Match Rifle hit the lower edge of a 25 yard pistol center at 100 yards, when set for it. Federal Gold Medal shot high of the 6" black. I lowered to 75 and got a fair center group with Federal Automatch. At 200 meters the 150 setting gave me a 6:00 group on the lower part of a 100 yard target's paper, and a 175 setting a 4" 3:00 group. This experience showed me that in the field or on the range, with the sunlight coming directly onto my rear sight my optical perception of windage is poor enough that I ought to pass up any shot with my tangents on my target and save some ammo, much as I love to shoot my CZs.
While one can move into a tree-trunk's shadow in the squirrel woods that is apt to send the target scurrying. I still have the Williams receiver sight on my Ultra Lux sighted in for small game. I think I shall keep it there a while. Good shooting to you all.
