I had two pretty consistent issues with mag loading. First was the force needed to push the cartridge down into the mag, second was that the last cartridge(4th) would almost always slip over to the far side of the mag well requiring me to roll the rifle over to the right to free the cartridge to fall back out to try again.

I haven't taken the rifle apart to check it out yet, had to leave for work when I got home today. Maybe something's out of adjustment.
