    The plot thickens.

    Adjusted scope mount and rezeroed with the Sako. Scored 0.75MOA group at 100yds. No chance to do 200yds but will report back.

    Also tried the MEN85 fmj and had 1.25MOA group, and Hornady superperformance and shot 1.75MOA. Sako group was third.

    TBH Belmont has been some of the most constant ammo ive been able to get my hands on shooting well above its purchase price, Might just be it doesnt like the Sako loads just because its expensive doesn't mean it will shoot great.

    Could this be a bullet stability issue with this ammo? Seem odd that it shoots ok out to 300 but turns to shit by 400???
    Experience. What you get just after you needed it.

    oh well you have learnt a couple of expensive lessons...... what used to be magnum imports..now???hut valley ...??? were always good to deal with,sure you have plenty of "better options" to spend your money with in future.
    your old belmont load wont be hard to duplicate for any half competent reloader..... heck a lee whackamole set should be able to do it.... reverse engineer it will give you some idea where to start...at a GUESS... they will be using a cup n core interloct hornady and win 748 powder or the equivilent belmont was selling and it will be say 3/4 of way up ladder,eg grain or two below maximum...that is WHERE I WOULD START...and probably finish too truth be known.

    Be about right - although to be safe I'd probably start at the start loads and just double check the load and components aren't going to do anything weird...

    The problem is subject to a steadily increasing error factor that increases exponentially. Bullet stability, velocity, wind, mirage, temperature variation, barrel harmonics, personal ability, etc. are all variable factors. Your first clue is that your rifle is shooting sub-MOA at 100 but only MOA at 200 which shows a creeping error factor at fairly short range. The easy way to imagine the compounding error potential is to imagine the error factor to be like a trumpet mouth; as the range increase the error factor increases at a greater rate. I believe your main problem is velocity loss from the short barrel (effectively 1-200 metres over a normal length barrel). Using match components in a specialised target rifle, the maximum consistent accuracy range from the .308 is in the 800 to 1000 metre area. In your case you are using a hunting bullet (designed for acceptable hunting performance at normal velocities at normal hunting ranges) at reduced velocity from a short-barreled rifle. Limit yourself to a realistic maximum hunting range of about 350 metres and it will be fine.

    Along the lines of what gundoc has suggested but I doubt it is your issue.
    He has a Remington 700 300 win mag that he has been mucking around a bit doing long-range shooting. older rifle, not one of the more recent shit jobs
    at longer ranges, I think past 400, it had a tendency to start throwing to one side. Not a lot but at it got further it corresponded to the shots on target as well
    He had already had a major shitfight with it using a lot of powder and primers etc until he found out it had a slow 1-14 twist and needed the appropriate projectile. Should've been a 1-10 to make use of the magnum case for bigger projectiles. but back on task
    Between Himself and another good friend where he worked (owns a machine shop) they worked out the back mount was on the piss. I think both rear screw holes for the base were off maybe 1/4 mm to one side. That's 10 thou to the proper people.
    He ummed and ahhed about it but got a carbide cutter of the appropriate size for about 60 bucks, set it all up on the mill (triple checking and gently recut the holes and it only needed tapping to the next size up.
    he was still dubious about it working and it being the issue in the first place.
    Well, it was. On a sporting rifle barely used out to 400 it wouldn't have been noticeable but once you got out past that it reared its head.
    must've been working a little bit like canting a scope. It was never in line with the bore.

    Yep, that's really common across a lot of the brands. Doesn't take much to make an issue where there shouldn't be and on a round receiver it literally does tip the scope to one side. Rem clones often go up to 8x36tpi screws from what is the standard (I think 6x40tpi?).

    What I think your issue could be is parallax error. Are you making sure you are 'dialing out' properly at the ranges you are having trouble with?

    (For newer shooters)
    Before shooting any new range you need to re-settle the crosshairs by unfocussing back and forth, in small increments. Bobbing your head till you confirm that your crosshair isn't straying off the target 1mm.

    If you don't do this you're at the mercy of the variation in your hold. It will blow out your groups. The error is almost imperceptible because your scope eye auto adjusts. But the crosshair wobbling when you bob your head a little tells you your focus is OFF.
