I had previously zeroed by mathematics and verified zero on the range, but hadn't had the time to shoot this one.
Today I had the opportunity to take it out for 40 rounds. A friend and I were shooting the Springfield 1903A3 and this, a 1943 Tula manufactured Mosin Nagant 91/30 PU sniper.
We put the target out at 75 yards. The first magazine was just to get used to the trigger, the 1903 has a shorter and lighter trigger than the Russian beast.
This was in in my better groups. In all my groups (minus the first) were 2 inch diameters or less.
