[QUOTE="CliffM, post: 1081089, member: 11533"] I found that RL-33 to be quite a bit denser than Retumbo, in fact Retumbo was the least dense of the powders that I have used in my 6.5 Sherman recently. Full case to the bottom of the neck: 72.0= RL-33 71.0= RL-26 70.2= IMR7828 69.0= IMR 7977 68.5= H1000 67.5= Retumbo Loading the 140 A-Max with: IMR7828 62gr= 3196fps IMR7977 61.5gr= 3188fps Very close to being identical. YMMV Cliff [/QUOTE]
