[QUOTE="RD57, post: 1860545, member: 103010"] Reduced loads from H4895 can do that sooting issue because the pressure isn't enough to expand the brass to completely seal the chamber. I found Accurate 5744 powder the best powder for reduced loads. Extremely consistent pressure, very low extreme spreads and standard deviations. A couple of my loads from my M70 270 Win Featherweight. Very close to 6.8 SPC velocity and energy with Sierra 110 grain spitzer or Nosler 110 Accubonds. 33.5 grains A5744, Win brass, Fed 210M primer, 3.221 OAL = 2765 fps, 5 shots, ES 11 fps, SD 6 fps, 0.33"@100 yards 31 grains A5744, Win brass, Fed 210M primer, 3.221 OAL, = 2677 fps, 5 shots, ES 1.8 fps, SD 1.3 fps, 0.5"@100 yards The Sierra bullets hold together very well at those velocities and mushroom like a big game bullet. No sooting on the brass at all. A5744 burns hot, so don't rush conduct rapid fire because you'll heat the barrel up fast. Contact Accurate Powder for more load data, they are very willing to help with other cartridges and bullet weights. [/QUOTE]
