    Looking for some more superior Knowledge:
    I have just started with the 338LM
    Working on [FONT=&quot]developing[/FONT] a Load, I do not know any one here shooting a 338LM, Looked in my books/on line, I have selected 2 bullets and 3 powders to start with.
    Went to the Field to do first round of testing.
    All groups were sub MOA, nothing class as a Bung hole. I could not see any major difference in group size. all 1/2 to 3/4 MOA

    Conditions: 73-75 Deg Overcast skies
    Wind: 3-5 mph straight from my 6 o'clock
    Elevation 6050 ft
    OAL 3.70
    Target heading 358deg
    Lat 39.53
    Humidity 38
    Barrel cleaned after each group and let cool

    Every thing shot in 5 shot groups
    Retumbo 89gr 285 HPBT 2843 (spread 15)
    90 285 HBPT 2896 (spread 17)
    91 285 Amax 2935 (spread 30)

    H1000 86 285 HPBT 2767 (22)
    87 285 Amax 2712 (7)

    RL 25 87 285 HPBT 2853 (11)
    87 285 Amax 2875 (12)


    I show no signs of pressure, bolt works easy on all loads:
    I will re-shoot the H1000 (87)Load not sure why higher charge lower velocity

    The Velocity looks a little high from books, but it was warm today and over 6000ft elevation.
    I just have no base line to compare with

    bung hole class

    Term is a OLD western term that i learned many years ago from some old old cowboys it refers to putting the shot thought the same hole.

    A bung being the pump hole on top of a barrel, lay the barrel so you only see the top of the barrel laying down and place the shot in the barrel with out making a mark on the top of the barrel.

    The one Bung shoot that I did go to outside Centennial Wyoming. you had 5 shells with the objective to put all 5 shots come out the bottom of the barrel with no entry holes on the top of the barrel. I did not do that well, only 2 went though the opening.

    Threading the needle or very accurate shots.
