[QUOTE="Greyfox, post: 782170, member: 10291"] I have not tried Reloader 19. I have heard that it didn't have the temperature stability of Retumbo, but that is information from a few years ago and they have done some work changing the formulation to improve the temperature stability of the Reloader powders since then. I get great performance with current Reloader 15 in my 308. I don't see why Retumbo wouldn't perform well in a longer barrel and you should be able to get at least 3100 FPS out of 29". I have gotten 3025 FPS out of my 26" Cooper with good accuracy using 59 gr of Retumbo with no pressure signs. I settled on 2970FPS because the groups shrink from .5MOA at 3025FPS to sub .25MOA with ES of 7FPS. I'll take the accuracy over that relatively small increase in velocity. It will probably give me a a little longer barrel life as well. [/QUOTE]
