[QUOTE="sambo3006, post: 115140, member: 2740"] I have a 26" LSS and I was able to get 3500 fps with the 140BT and 3400 fps with the 150BT. Above these velocities I got extractor marks, flat primers and a big velocity jump for small powder charge increase. I would say 3300 fps with the 160AB in my gun. Interestingly, I got the best velocity from IMR 7828. I also tried H1000 and got pressure signs at lower velocity. With 2" more tube and heavier slugs, H1000 or RL25 might be just the ticket for you. I would think that you could safely get 3400 fps with the 160 from your 28" tube. [/QUOTE]
