My club is starting up an event for antique military rifles. After
hearing all of the rave reviews here and other places, I went out and
bought a Mosin Nagant 91/30 the other day. It seems to be in fairly
good condition and shoots reliably but is consistently about 8 or 9
inches high at 50 yards which is the distance for our event. The rear
sight is down all the way. The gun must be totally stock for the most
part - no scopes or replacement sights are allowed which sevely limits
the options.

One thing I was thinking about was cutting the notch in the rear sight
a little deeper. Any ideas on that or anything else?

The iron sights on this rifle are set for 300 yards. When I was
researching mine I found that little tidbit somewhere in my research. If
I can again find the article I will link it here but it will not be
until the weekend that I will have time to look. Anything less than 300
yards will be high.

From everything I have heard, a standard battle zero is 200 yards and
the assumption is that a center of mass aim will still deliver a
debilitating hit anywhere from point blank to almost 350 yards.
The high point with 7.62 NATO will be around 120 yards and a few
inches. If you did zero at 300, you would still only be about 6" high
around 170 yards.
Bear in mind European/American strategy was that a wound was as good,
if not better than a kill. The assumption was that the enemy would
expend resources saving a wounded guy. When we started dealing with
Asians that did not always ring true.

If you are 8" high at 50 yards you will be zero again at about 600.

I don't see the data for the 7.62-54

My battle zero with the M-14 was 100 yards. I'll never forget that!
