Russian surplus 53 grain 7N6 vs Silver Bear 60 grain
7/24/2010 3:44:45 PM
I'm considering switching to Silver Bear for plinking purposes. There's nothing wrong with Russian 7N6. I just know that it isn't gonna last forever so I don't want to shoot it all up. It's great ammo and I'd like to have a few cases of it years from now. Another benefit of Silver Bear is the elimination of the need to thoroughly clean every crevice of the rifle.
Which brings me to my question–– If I am zeroed for 53 grain 7N6, how big of a difference in point of impact will there be with the 60 grain Silver Bear? Probably a little bit lower? And vice versa...I'd have to aim a little bit low with 7N6 if my SGL31 is zeroed with Silver Bear?

With my 74, with any ammo I can hit one of four walls from inside the room. IMHO 5.45X39.5 is much more accurate than 7.62X39

I did not notice a huge difference in average POI from 7N6 surplus and some Romanian 60gr. non-corrosive I purchased from Century. However, the group size shrunk from ~4" extreme diameter @ 25yrds with the non-corrosive Century HotShot to a little over 2" with the genuine 7N6. This was shooting from a standing position.
Yeah, I suck

The Russian GI ammo surprised me, too. I ran a few rounds through my runout indicator, and they were uniformly near match specs regarding concentricity. From a rest, my SGL31 shoots 7N6 to 3.3 m.o.a. @ 150 yards.
Wife wrinkles up her nose at the mess in the guest bathtub, after cleaning the rifle,though ! I can't imagine why Russian ammo, dated 1982, was still corrosively primed.

I have shot some 1992 bulgy that was still corrosive
and i get about the same accuracy w/ my rifles.
If its like my AR, more than likely the POI will be slighly shifted to the right w/ a heavier bullet. Zero w/ my 75gr TAP and 60gr Ranger was shooting 1inch left @ 100

It was not for a lack of technology that they didn't switch to non corrosive primers. I believe it was because corrosive primers have a longer shelf life and are more reliable in cold weather (think Siberia). Cost could have also played a role.
