    Went out yesterday to shoot the Cutting Edge .375, 350grain at 3050 fps with the GS Customs 414 at 3130 fps.
    The Cutting Edge were shot out of a 375 Terminator, this barrel has always been problematic, always badly fouled after 25-30 rounds.
    I have tried everything I can think of but it still does it :rolleyes:

    With two bullets remaining from yesterdays shoot, I went the range to check it's zero this afternoon.
    It was as it should be & put the two in the same hole less than 1/8 moa group, with plenty of copper clearly visible in the muzzle......

    The end result was .25 moa difference in elevation, 4.5 moa in windage, some small sub moa groups & a broken rock :)
    I'm not entirely sure why there was such a big difference in windage ?
    The elevation difference was about what I expected, in my rifles at that distance the 350 does appear to have a higher BC than the 414, especially when you take into account the speed difference.

    Here is the video at 2050 yards the rock is a different one to last time & slightly bigger, under 1/4 moa, 3-4".

    Thanks for a great vid Greg, some very interesting results between two totally different 375 bullet weights.

    PS: When you get above 60 power the mirage almost disappears. How do you think they get pictures from satellites in orbit without any mirage?

    Here is a trick that TOP long-range target shooters use:

    I think you are correct and now I don't know what thread I should have posted. I guess I'm getting Ronald Reagan disease. :D

    Not sure where you meant to put this but I have tested a few hi end scopes including the 8-80 March, sorry I didn't rate it for what I need in a scope.

    The total internal elevation would limit me to around 23-2400 yards, I dialed 102 moa to shoot 2910 yesterday :)

    The Thread won't allow me to delete Posts #4 & #5. Hopefully someone can help me out by deleting them for me.

    How was your day at 2910, a good one?
    Were you running the 350s, 377s or 414s

    Had a good day thanks :)

    Except for a flat tire & tipping up in a creek giving myself a bruised shin & inside knee when we went for a hunt.

    I got pretty close on the fourth shot of the day from a guessed dial, I should have trusted the programme :)

    Also had a few problems sticking to shooting at the same rock :rolleyes:

    I was struggling to understand what was going on at the time, but veiwing the footage on the big screen it is plain to see.

    I haven't had time to put the video together, it may not flow very well with the different points of aim, I may have to do it again.

    The 425 Cutting Edge was the only projectile I shot.

    I didn't try the 414, I don't think they would have got there, my data shows them being transonic at 2500 ish & 130+ moa up.

    Next time I go up there, if conditions allow I will have a go with the 414s

    Would you mind telling me the twist rate (starting and ending) on the barrel.

    Also I'm interested in the contour. Last of all are you happy with your choice.

    Twist 12-7.25-1,

    0.92" muzzle to 1.35", 4"-5" knox.

    32" long.

    Very happy with the barrels :)

    Please excuse my thick headedness; that is a 1 in 12 starting twist rate and ending in a 1 in 7.25 rate?

    If I understoood that correctly my next question is; are you able to shoot jacketed bullets, like the 350 SMK?
