    "inexpensive?" 2000 yd group and score based on a 111 action first range reort


    since this is basically a "new " cartridge ( 3.82 long 300 win mag)
    i chose to shoot a ladder just for velocity. checking pressure as i go.
    i will not list the loads as they are unique to this rifle and chamber.
    the bbl is nitrite treated, hbn on bullets and bore.
    berger 230 bullets and vvn570 powder in federal( yes federal) cases, fed 215 primers
    i am trying to find a load around 2900 fps from a 9 twist bbl 27.125 long with a suppressor.
    86-92 degrees 30% humidity
    2828
    2856
    2867
    2894
    2898
    2929
    2940
    2974
    2986
    NO pressure signs, easy bolt lift, no ejector marks
    heat was present in the later shots, might be an issue in a 5 shot string.
    its ok..i hit my mark (2900) in the middle if the test)

    to continue..why do this ?
    basically a new cartridge
    the numbers are aprox 75 fps FASTER than predicted by software,
    while having no indications of pressure issues, easy bolt lift, no ejector mark on the case head, primer still has a rounded edge.
    i can now do some real load development, off a front rest, maybe with some distance 200/300 yards.
    two things to note
    1) THE BEGINING LOAD 2823 is super sonic past 2000 yards at my match elevation;
    2) ignoring the first cold bore shot, sighters 2.3 and shot 1 of the string
    had an average of 2822, and an sd of 1.5

    ( yes shot 1 is 2823..not 2828..typo)

    did an actual 200 yard, 9 shot ladder with both velocity and location.
    i'll post some data later, looking good for velocity goal.
    here is the break down
    all done at 200 yards
    2821 to 2988
    shots
    234 had .47 vertical and 2886 ave velocity
    345 had .48 vertical and 2911 ave velocity
    567 had .2 vertical and 2942 ave velocity
    i will probably shoot 3 shot groups of these 3 and see what happens
    so far do good

    You have what looks like 3 rifles on one post at Gunboards. Difficult to follow. But here they are. ^^^^^^

    i shot the three loads mentioned above at 200 yards.
    nothing interesting. the small group load 2 was over an inch at 200.
    5000' and 75*.
    scratching my head and thinking.

    Maybe you should get some gold medal match. I used it to score a 697 28X's @ 300 last weekend. HAHAHAHAHA!

    All kidding aside could it be the nitriding finish?

    not that i know of.
    probably a dozen shooting disciplines on over 2000 acres.
    i only shoot on the benchrest range, shared with a castbullet/22 group, the 1000 prone range, and the commercial 5-200 yard range( 67 shooting positions).

    what does he do ?

    i use their practice times to shoot OFF A BENCH at 600.
    as long as i run pits they do not care about my bench.

    so back to the range today
    trying to fine tune the load
    three 3 shot groups in small 0.2 grain steps
    2 of the 3 were just a tad over 1 inch at 200 yards, third had a flyer.
    so 1/2 moa, go do a seating depth test..but

    here is the big issue
    group one went 2" right of hold/center
    group two goes 4" right of center
    group three goes 8" right of center
    all are water line/level
    i have never seen a poi movement like this..never
    solid mount. new scope( nf 12-42).
    ????????????????????????????

    so after discussing with a few people
    re-shoot with a different scope.
    scope is changed out, new ammo in the same cases as before,
    plus some sighters to dial it in with

    re-shot today..at 100 not 200
    NO CREEPING TO THE RIGHT.
    zero'd new scope at 40, then at 100,
    shot three 3 shot groups just next to point of aim.
    one is really small , 0.320"
    so the offending object is either the NEW night force scope,
    or the ivy 150 moa rings.

    so back to the range today with the nightforce 12-42x installed in regular rings.
    no 2,4,and 8 inch jumping to the right.
    so it would appear something is a miss with the ivey 150 moa rings.
    i will call and talk to them.

    disappointing is the inconsistency in groups. always a flyer.
    me thinks there is an ignition issue with the bolt assembly.
    inconsistent firing pin hits.
    comments ???

    i can continue load development with the fixed rings, just no
    2000 yard shooting. 600 is easy.

    Has the bolt been messed with? If you disassemble it look for parts that are binding like the fit between the cocking piece sleeve and the cocking piece. Could be some burrs in there.....maybe. No lube going back together except maybe ford friction modifier .

    What about pin protrusion?

    I have......one time I was doing load work up at 1000 yds, and inadvertently loaded BR-2's instead of Federal 210's (the priming tool was loaded with CCI and I didn't realize it). When I went back to shooting, the point of impact was 2 feet higher. I thought the scope took a crap, till I realized my mistake. Turns out it was more of a "happy accident" because it shot better all the way around.
