[QUOTE="dwm, post: 4434, member: 1136"] Started with H4831SC. It worked well. Case not full enough for me though. Then thought that since I had 8 pounds of Hodgdon Retumbo laying around for the 7mm RUM I would give that a try. (Going for max load density.) Here goes: Rem 700 Sendero Stainless Fluted 26" Barrel Factory trigger adjusted to ~2 pounds Leupold 6.5x20 50 mm LTR Standard 30 mm Leupold mounts Hodgdon data for a 25-06 with Retumbo (24" barrel) states: 117 GR. HDY SPBT (Starting Loads) DIA. .257 COL: 3.165" RETUMBO 56.0 grains 2876 fps 44,600 CUP 117 GR. HDY SPBT (Maximum Loads) DIA. .257 COL: 3.165" RETUMBO 60.5C grains 3079 fps 50,700 CUP First thing was to find where the lands were. Got out the Stoney Point and figured out what depth to seat the bullets. (0.005 off the lands.) Also, all brass was fire formed, trimmed, neck turned, and only neck sized. Started with 58.0 grains Retumbo and worked my way up to 60.5 grains. Using Fed GM 210 Match large rifle primers. Shooting Chrony said the average velocity with 60.5 grains Retumbo was 3135 fps. Max velocity spread was 23 fps over 10 shots. 115 grain Nolser BT or Partition shoot almost exactly the same. Didn't move the seating die. It also likes the 85 and 100 grain Nosler BTs. (85 grainers will go 3350 fps out of this rifle.) Don't start at the max load, your chamber may be different. Work your way up to max. [/QUOTE]
