    Used the following:

    190GR Sierra MK
    VV N165
    Federal fire formed cases, neck sized and trimmed to 2.08 -2.11 (still getting a hang of this trimming thing)

    CCI LRM primers (managed to crush two while seating)

    71 to 74.5 grs in lots of 10 to test in two groups of 5 at each step. (80 cases)

    Plus 10 each using strela(?) cz origin FMJ BT's 150 grs at 73.5 and 74 grs.

    Each charge wieghed individually on a RCBS 505, whithout a dose chucker. Essentially scooping and trickling powder using a trickler and a .357 mag case soldered to a brass handle that someone gave me.
    (My Lyman DPS has gone for replacement)

    So will head to the range on Saturday and spend at least three hours firing this lot off depending on how the barrel heats up, and my shoulder lasts.

    Should I fire one group of each level or complete the level and then move on?

    Also while loading I suddenly got foxed when my OAL jumped from 3.38 to 3.44 without any die adjustment. Took me a while to figure out that the calipers had lost their zero... :rolleyes:

    Learning continues... :)
