[QUOTE="Joel Russo, post: 255203, member: 6152"] Since Retumbo and H-1000 are so close in burn rates, pick one and start around 89-90 grains. Move up one grain at a time while measuring case stretch to determine when you are approaching max load. Don't exceed .005". You'll find it somewhere around 93.0 with Retumbo and maybe a grain or two more with H-1000. [/QUOTE]
