I have the program in the handheld and just used it for the fist time today at 1000yds. I was using my 300 Ultra and 180 Ballistic Silvertips at 3190 fps. Punched in the Nosler BC of .507, temp etc and came up with 26.2 moa. Well, a bit more than I had thought but I let her rip anyway and hit center mass, first one on the 13.5" x 18" steel plate!
John, I was using the True MOA setting too. It is working better than the SMOA, more on it later.
My wife and I were out shooting at 500 yards yesterday. We dialed in a good zero at 100 yds first and checked velocity on the 243win and 300 Ultra. Hers using 95gr BST and mine the 180gr BST. We went back to 500 and both were on the steel with our first shots. Mine took 7.5 moa and hers, 14.4 I think. The program was on the money each time with both guns.
Two in the middle are the 180's and one on the bottom just right of center too. The rest of them are my wifes first time out past 200 yds using the 243. No load development with these bullets yet just some random loads just so we could get out the door and clang some steel. Both loads all shot under 1.2moa at 100 yds with half of them just under .7moa.
This is at 1000 yards today with the Ultra and the same load. I had three rounds left from the day before. One missed the plate, the one that looks like a hit on the right is actually a 400gr 416 bullet, been forever stuck in the plate.
These are some 180 Scirocco's I had loaded. First group was high left and the second was a little right after adjusting it down and over. I think the 2mph wind at 2 O'clock just let up at the same time I moved her over to the right. I lost two shots off the plate on the rt group.
I'm really happy so far with the Horus program, it just works great in the field.
