Walter Rego, Does any of your factory Norma ammo possibly have a tiny "NP" stamped of the primers? I ask because I've used a fair amount of the old Norma, mostly the 200 grain, back when Norma was the only 10MM factory ammo available. I've chronographed quite a bit of 10MM since those days. I found that even though Norma did not change the listed 1200@200 on the box, the later ammo, marked with the tiny "NP" on the primer, was loaded to lower velocity. About a hundred FPS less than the original in my 5" S&Ws.
ETA, I had a couple of 1006s, 1026s, and 1076s. I think the Op's and other's adjustable sighted guns are the way to go since there is such a range of bullet weights and velocity ranges available with 10MM factory and reloaded ammo. I like my current 1026, but would still prefer adjustables.
