Scotty,
I've used about every possible combination with the 160s. Retumbo, H1000, 7977, 7828, R22, R25, R26. My rifle is throated long, 160 ABs touch the lands at 3.670" so bullets get plenty of jump. Accuracy is very good overall with this throat length, especially with TTSXs. Bob and I had many conversations about this and we both came to the conclusion that I just have a slower barrel. 3150fps is about it's limit before case life goes down the drain. I don't think that another 50-75fps means much anyway.
For sure. I don't sweat it too much either. Just surprises me how some do it easily and others struggle to get there.
