    Id say Normies barrel is getting on the short side to get those speeds from a 260, and as you know a longer barrel will get more velocity for the same pressure, so pressure and velocity are not exclusive to each other.

    If his loads are doing the 2644 the crony says they are then it only really leaves a scope adjustment issue dosent it?

    It could be an issue of the scope being near the edge of adjustment and the adjustment fucking up because of that - how much travel have you got from zero? Up, and sideways. I had a VX3 that would go sideways when you got near the top.

    Barrel length doesn't make that much difference.

    I dont agree with you on barrel length, I find it makes a big difference especially on 6.5's. Build yourself a short barreled 6.5x284 and see how it goes, they are fucken useless!

    We're talking a 22" .260 here though, not 12”....

    But on the subject,

    Tussock cut his 6.5x47 from 26" to 22" with loss of 10fps. His load of 42gr was exactly the same as mine (my load development initially consisted of pinching ammo from his shed when I was in a hurry) and doing about 2fps different average out of my 20” to his 22”

    We got nearly 2900fps from a 20" barrelled BSA 6.5x55 back in 2009 with N560 when we got snowed in and had nothing better to do, without any real pressure signs

    Norway has a 18.5" 6.5-284 and enjoys it - although he is very conservative with his loading compared to all of us.

    Ok Gimp, you must have stumbled on a secret that no one else has ever discovered. I wonder why we all walk around with these long barrels then? We must all be stupid.

    I don't understand what you think is so shocking about a 20-22 inch barrel? Yes you get more speed from a longer barrel. Yes the returns are diminishing the longer you go. Yes long barrels are a pain and I don't like them and don't give a damn about the theoretical 50fps I'm missing out on. Longest I have on anything is 20" and I definitely haven't noticed any downside at all.

    It's not particularly crazy to expect Normie to be able get 2700-2800 fps from a 22" barrel with what is widely considered the optimum powder for the cartridge when a heap of people are reporting doing just that, when I'm doing it with a 2" shorter barrel and a smaller case, and when he is getting that with a different powder?

    Gimp misinterpretation of poi isn't a lie its an error but I sure you know what I was referring to.

    Id check the imputs and shoot some groups on paper at range.
    Just a slopy retrobate

    Short barreled 6,5x284 out to 1150 meters, 20" and not 18,5" as Gimp said.


    You'll get:
    A compact rifle that let's you react fast enough to make use of the shooting opportunities.
    Reduced velocity and reduced supersonic reach.
    For all practical purposes, no change in wind drift.
