There doesn't seem to be much interest here for the Mosin Nagants but I thought I'd try one last time.
Many people believe that the Soviets took sniper rifles that were worn out and returned them to standard infantry rifles - they were less worried about accuracy in a non-sniper. This example will help to disprove that notion.
I'm prepping for a vintage Sniper Rifle two-man competition next weekend and wanted to zero my restored ex-sniper (1942 Izhevsk with a '42 Progress PU scope) and confirm whether it was going to be my competition rifle or not (I have 2 other M91/30 PU snipers). I shot it last week with MILSURP ammo and it was pretty good. I had started hand loading my own ammo and had 10 rounds that I shot at the end of last week's firing. I thought I had a pretty good zero but still wanted to confirm.
This week while loading with an inexpensive digital scale I had done about 20 rounds and the scale started to act strangely. I ended up with 3 rounds that I believed were under-powered - and knocked my loading tray over so they were mixed in with the bunch of 25. I got a new, much better digital scale for future use so that problem is now gone.
So, today I went out with 25 rounds to validate my zero using the hand-loaded match ammo - using 43.5 gns of Vargent Powder, Winchester primers and Sierra 174 gn .311 boat tail bullets.
First 5 rounds were fired at the lower left target and all placed just right of center. The next 5 hit 3 bulls and two just right.
The next 10 rounds were fired at the lower right target - and in each of the 5 I got one of the low powder rounds.
My last 5 rounds were to validate the fine adjustments I'd made in the first 20 and were fired at the center red bull. 4 dead on bulls and the last of the low powder rounds.
This thing is a tack driver.
