I still remember when one of my friends first asked me to order him an IOR scope. I said, Who is that, never heard of them. But he insisted that he had read good things about them. So I did a little research and called up Valdada Optics. Before long, a 4x24 308 scope was on my doorstep. Within minutes of opening the package and viewing the clarity of the little combat scope, I was back online doing more research. It wasn't more than a couple of weeks until I had my first 2.5-10x42 IOR with the modified mil-dot. It was more than I expected for my first Valdada. It was tough, had precise adjustments, and was the clearest scope that I had ever owned. I used it for more than a year shooting at shorter ranges here on the family farm from 100 to 400 yards. I was satisfied until Valdada came out with the 10x42 fixed power scope with the side focus knob, and of course the new MP-8 reticle. Well I had to have one. It has been on my custom GA Precision 308 Win ever since.

Shortly after, my interest in long range shooting grew and I decided it would be nice to find some sort of competition. After looking into it, my friends and I settled on F-class competition. Two of us shoot 308 so we would be classed F/TR which is F class tactical rifle. It is limited to 308 or 223 prone with scope and bipod. Rear bags are permitted. Some of the others will be shooting F-class open in which the caliber is open to wildcats or large 300 mags. In open class you can use a front mechanical rest and a sand bag rear rest. We had been going to practice at Camp Butner, NC at the NC National Guard known distance range. It has 50 shooting lanes and berms from 100 to 1000 yards. After a few trips to the range, more of the guys had become interested in the IOR scopes. We had shot in 34 degree rain and 98 degree heat. My Valdada did not fog, leak or miss a beat anytime we went. Soon the others began to switch sides, even my brother the diehard MK4 fan. One day in September of 2005, we almost had a miserable day at the range. I say almost because any day at the range is better than a day at work. It was hot. Hot and humid, and the haze was terrible. My scope was clear as a bell. I shot great that day. After looking at both scopes in the haze that day, my brother's custom 300 Win Magnum now wears an IOR.Butner at 800 yards

We had practiced, tried different loads and hoped we had everything ready to shoot at a competition. I had my GA Precision Remington 700 in 308 topped with the 10x42mm side focus with the MP8 reticle. One of my friends had a DPMS LR308 equipped with a Magpul Precision Rifle Stock and a 4-14x50 side focus with the illuminated MP8. We both shot in the F/TR class. We had practiced up to 1000 yards but never actually shot in a NRA match. The first one to come up was the NC State Long Range Championship. It was to be shot October 28-30 for three days at 800, 900 and 1000 yards each day. I was not quite as prepared as I should have been. Neither of us had a spotting scope for judging wind and mirage. I figured that the wind flags would be enough. I will not miss that next time. I was still able to come out of the event with a 2nd place finish in my class. For three days we adjusted the scopes up and down for the different distances and back and forth through the fishtail winds. By Saturday, I had full confidence in my equipment. The only thing I had to worry about was missing a wind change. Several shooters on the line stopped by to look at my rig. Most liked the gun, but even more were impressed with the clarity of the scope. I don't think any of them were more impressed than I was. Every day, the adjustments from 800 to 900 and then to 1000 yards were the same. About a month later, I shot the 600 yard F-class match at Butner and came in 3rd place in F/TR. My first two matches, second and third place finishes in both. Happy? You bet I am!
