I took my Mosin and Argentine Mauser out today. I was shooting the Mosin with the irons at 25 yards. My loads with speer .150 grain 311 bullets and 14.5 grains of green dot were very accurate. I was getting groups touching each other on the target. It's the best that rifle ever shot. They were hitting where i aimed but a little left. I also loaded some berrys 123 grain .311 with 20.21 and 22 grains of 2400. The key hole issue i had solved. But they were hitting low.
I had to move the rear sight up a notch. They were close to where i was aiming height wise. Some spread out though. Im just trying to figure out why they would be hitting low. I wish i had bought my targets home and took some pics. The Mauser is the same way. I only loaded 2 rounds with the 123 grain and 22 grains of 2400. I had 2 casings mixed in my 762.54R casings. So figured i would load them since the powder drop was set up already.
