Okay, you guys got me doubting my shooting skills now! I'll have to pay more attention to that.
Last night I managed to get 52gr of Retumbo under a 140gr Speer pill. The powder came halfway up the neck and the bullets seated about even with the bottom of the neck. Was able to make pressure too with the once-fired cases showing 2-3 "tenths" CHE. At least now I know Retumbo isn't necessarily too slow. It certainly changed something! They printed about 10 inches lower and 4 inches right of my H4350 load. Unfortunately, it didn't group any better, about 4 inches at 200 for three shots. Something's goofy, and I hope it's the shooter.
Will try the same load again tonight with a different shooting technique (holding the rifle in my hands instead of resting on the sandbags). It may be bouncing off the bags.
