After waiting for things to slow down on my bridge repair job this summer I finnally had some time to get this new X.O.T.I.C USS mounted to my bolt gun to give it a good workout. I purchase the USS from SWFA maybe 8 months ago, its been in the box ever since, but no longer!!! I know I am always interested in reviews on hardware especially non-brand name hardware like this. So here is my 2 cents on the performance and operation of this gem:

Test rifle:
Remington 700VS 308win
26" Heavy Barrel (conditioned previously)
HS-Precision Police Stock
HS-Precision Steel Floorplate
TPS Tactical Rings and Bases (Steel)

Test Loads:
Handloaded Sierra 110gr Varminter HPs on fireformed brass
Handloaded Sierra 168 HPBT Match on fireformed brass

This rifle with my Bushnell Elite 4200 4-16x50 can shoot thru a dime all day long at 100 yards with either handload. So I know this rifle cartridge combination works. Prior to mounting the USS I sent a group of each downrange to make sure this latest batch of handloads wasn't crap. Everything functioned as it normally does.

Accuracy Tests

After I got this mounted properly and zeroed it in on the paper I began five shot group accuracy testing with both handloaded bullets at 100 yards. I take the best 4 shots to determine my accuacy group as one flyer here or there is usually some sort of user error. The barrel was brushed and allowed to cool between shots. I fired three 5-shot groups with each bullet type for a total of six groups total, or thirty shots fired. The best four shots of each group all shot within a dime. If your interested in the CTC distances I suppose I can put the calipers on them, but its the best accuracy I personally can achieve with this rifle.

Tracking Tests

To test the turrets I put a 10'x10' piece of cardboard out at 100 yards with an orange spot. I put one group at the zero mark. I went up 12 minutes and left 12 minutes put a five shot group. Then I went 24 minutes right and put a five shot group. Next went 24 minutes down and put a five shot group. Then I went 24 minutes left and put a five shot group. Lastly I went up 12 minutes and right 12 minutes to re-zero and put one last shot. I really need to buy a digital camera so I can capture this paper but you have five dime sized groups in almost a perfect square.

Optical Clarity

Since I don't own an optical comparator or a planar-waveguide intergrated spectral comparator I will do my own extremely subjective clarity test with my own eyeballs. I compared the USS to my Bushnell 4200 in 4-16x50 and my buddy's Leupold Vari-X III 4-12x40. Both the USS and the Bushnell have a cooler tint to them, the Leupold has a warm tint. My personal preference is for a cool tint. We took a Snellen Eye Chart we printed to scale off the internet and stuck it up there at 50 and 100 yards and tried reading the letters. Since everyone's eyes are different any random person who showed up to the range that day I asked them to try and read what they could on the chart at 10 power and up. I asked that they try to read the chart at the center of the scope, then move the eye chart near each edge of the scope and tried to read the chart again from the top, bottom, left and right of the lenses. The damnest part of this test was the back of a paper bag I used to write the results on is MIA. As I am writing this the shop is torn into pieces. I WILL find it or repeat the test but we haven't had a clear day here in weeks.

Observations

The parallax knob calibration is pretty damn close to being on the money. Our range goes in 25 yard increments from 25 yards to 200 yards. At each respective range the knob is practically dead on except the 25 yard target is a tad too close and the knob bottoms out before focus can be achieved. Not that anyone here is making 25 yard shots with a 16 power scope anwyays but I put it on there just because.

Fit and finish is excellent. The finish is very very hard. On an obscure side where no one would see I took a common nail and tried to make a scratch or gouge in the finish. After bearing down with some signicant force and still causing no visible damage, I can conclude the finish they use is superb. The knobs and the rear focus ring were stiff. Really stiff. Even after cycling the knobs thru the full range a few times as the manual suggests and after all the testing and shooting they still retain that factory tightness. While my first instinct would be to complain because it seemed too tight for my personal prefernce, it does speak to the quality of the machining and assembly of the scope. You don't wear this thing out, rather, you need to break it in.

I dropped it. Well not on purpose of course but on two occasions both myself and my buddy had the rifle accidentally slide from our hands on the relatively cold day of testing. Each time the scope hit the concrete range slab with a heart stopping clank. And after inspection, there was no visible damage, no loss of zero. Says alot for the scope and the mounts.

My laser rangefinder has yet to be purchased, but when it arrives I will place targets of known height at various ranges and use my mediocre skills using the Mil-Dot system to test the USS reticle. I am trying to find someone who has alot of experience with the Mil-Dot system. It's my humble opinion that personal ability to use the Mil-Dot effectively will increase substantially with practice.

Thats all for now. If I can find that fosaken paper bag I can post those eye chart results. I hope this post can be a help to someone.
