I am testing some rounds for my 280AI with 26" barrel and 1 in 9 twist. I am working on some 160's. Nosler AB and Speer SPBT. I have some RL 23 and 26. I have others but they are all posted on the Nosler load data. If anyone wants to chime in on these powders they are H4831SC, IMR 4350, RL 17 and 19. I have tested the IMR7828ssc with a 162 Hornady Interlock SPBT. The results were decent enough to take another look at that powder. I would like to see what the 23 and 26 will do since they seem to have a good following on this site. Thanks, Alan
