[QUOTE="ksubuck, post: 1299168, member: 64792"] I must have slow barrels. When using RL33, my 7 STW pushed 180 VLDs at 3225 max, accuracy load 3080. My 7-300 WM max 3125, accuracy load 3075. Both have 26 inch barrels. My 7RM has a 24 inch barrel. RL33 topped out at 2990 with the most accurate load running 2900. The max load was fairly compressed. I can reproduce very similar to the same velocities with Retumbo. I stuck with RL33 in the STW, Retumbo in the 7-300, and IMR 7828 in the 7RM as those were the most accurate powder in each rifle. I also bumped down to 168s in the 7 RM. Also, Retumbo does appear to be much more temp stable than the other two. I saw 0.4fps/*F change with Retumbo, 1.0fps/*F with RL33, and 1.3fps/*F with 7828. If the powder produces a wide node in a rifle that is not a big deal, but with a narrow node it makes a bunch of difference if shooting at distance. [/QUOTE]
