    Ran some more loads and got similar data. Going to start again with a new bullet/powder combo and do the work up in .3 grain intervals.

    Have you tried full length resizing with only a shoulder bump? You can FL resize every time, and use a comparator kit to only bump the shoulder back a desired amount. Repeatable. You get consistent without sticky bolt movement.

    Maybe for long range shooting, but not for ranges normally found when hunting.
    Most are stuck at 100 yards, with no 200+ ranges around them.
    Within 200 yards, I have never found low SD/ES to mean anything in terms of accuracy.
    The ladder is good, but you really need to shoot at 300 yds or longer and you really have to let the barrel cool. You can spend all day shooting 10 shots.

    Alright ingo,

    Strange things are afoot at the circle K.

    Did my load up and ladder test via 6.5 guys tutorial.
    Started at 57.5gr and stopped at 60.2(bolt lift resistance)....in .3gr increment.

    Practice is to fire 3 shots and let cool.
    Velocities are as follows.
    2881
    2908
    2921
    2963
    2950
    2950
    Error, 2992
    Error, 2988, 2981
    3030
    3089 with heavier bolt lift.

    The errors where reloaded and fired again within 45 minutes.

    The two 2950fps loads is where i decided to load 9 rounds and shoot for a group.

    After a through cleaning, the first round showed 2674fps cold bore, clean.
    Then
    3003
    2997
    2997
    3078
    3105.
    Stop...velocity climbing past my max load?

    I was shooting in direct sunlight and let the rifle cool between three shot strings. Ammo was out of direct sunlight.

    So...as the bore fouls velocity goes up? Dangerously?

    This is a 26in shilen stainless barrel with 300rds...so it should be broken in

    Didnt group that well

    Shred?

    Did you mean 2974?

    Still, you have over 100 fps variation in only six rounds. The internal ballistics of your load is not happy. Are you using a standard primer or a magnum primer? If standard, that is probably the problem.

    Side question, are you using RL-23 or H4831SC?

    What i typed was correct. ...26xx
    These results where with rl23

    I have magnum primers but have not used the in this rifle...i will give that a shot, but i only have federal gmm magnum primers...so limited for choices.
    Nosler and hodgdon data calls for a standard primer....not that i have data for rl23....


    I have used wincheser, cci, federal, and federal gmm...the wlrp had the tightest spread in my initial testing so that is what i stuck with.

    I have not seen near the swings with h4831sc but it also was not as consistent on average... makes sense huh?
    When rl23 is slow fired(10 min cool down between shots) i get very low spreads...like 10fps.

    Im not blasting off rounds as fast as possible but if it takes me and hour to shoot a single 6 or 8 round group, then that is not my idea of fun

    I emailed shilen and alliant with a few questions.

    Thanks for the reply and will try the mag primers.
    Just thought that with less than 60 grains of powder i wouldnt need them?

    Alliant and shilen didnt offer much help.

    Called the chronograph manufacturer and they said they would send a replacement, but i havent seen anything yet.

    As for more shooting...ive primed and annealed 20 cases with federal magnum match primers...and thats as far as the wife/kids/job/house have let me get.

    Thanks for asking... will update when i can.
