Looking like a good starting point to start playing with seating depth. I have a 243win with a 22 inch 1:9 twist, ive been playing with berger 95 grain classics. With H4831sc i couldnt break 2800 fps. Accuracy was terrible as well, i switched back to Imr 4350 and accuracy is good and speeds are 2950 fps. I was wanting to try H1000 but i think in the shorter barrel it would be a wash. If you want to get more Retumbo in the case get a 6" drop tube.
