  • 250gr., gas checked bullet, 9.6gr. SR 7525, FC. 308 cases, #34 primers, oal= 2.518", crimped, Mild, a little soot, 1061 to 1079 fps. 10 rounds, 3 shot 1/2" group at 50 yds.Notice again the low velocity spread.

  • 297gr. gas checked bulet, SAME. oal=2,425", mild, 1040 to 1062 fps., 2" group at 50yds. ( (may not be stabalizing at this velocity.Faster loads with this bullet have allways been good).

  • 158gr. FMJ rn. 26.5gr. 4227, WW 06 cases, #34 primer, oal=2.122",. mild, 1936 to 2004 fps.3 shot 1" group at 50yds.

  • 250 gr. WIN. Jacketed FP., 30gr. Turk powder, LC74 cases, WLRM primer, oal=2.520", not max., 3 shot 1/2" group at 50 yds.Chrono took a dump in the sun, was trying it without sun screens.

    AND A LITTLE MORE

  • .243, 100gr. BT Spire, 14.5 gr. SR7625, RP. ni cases , #34 primer, oal=2.745", Mild, cool barrel after 5 shots, maybe a slightly hard bolt handle lift, 1893 to 1925 fps., 6 shot 1" group at 50 yds.

  • .243, 100gr. sp Mid South Bulk, same loading, oal= 2.735", 1770 to 1807 fps.primers just a little flat., 7 shot 1/2" group at 50yds. 5 shot 1" group at 200 yds. Just great at 200 yds.

  • .243, 100gr. BT Spire, 40.6gr. 7383 lightly compressed, RP ni cases, #34 primer, oal=2.768", 2778 to 2941 fps. some unburned powder,( very little), NOT GREAT.


  • .243, 100gr. sp Mid South Bulk, same loading, oal=2.782", 2728 to 2863 fps.4 shot 1" group at 200 yds.

    The SR 7625 really shows promise but like the Blue Dot loads extra care must be taken when loading. The velocity spread for the small amount of powder in a case was certainly surprising. I may be rediscovering the wheel but SR7625 looks like it may be excellent for cast bullets.
