Not sure if this is the correct place for this, but...
I frequently go to a 1000yd range. Lots of Fudds out there. Most are complete idiots. They setup their $600 .308 AR topped off with an NC Star optic and go "Never been here before, but that 1000yd gong gonna ring!" and end up having to move to the 75yd berm after firing dozens of rounds with no idea as to the whereabouts of their impacts. I want to be clear that this is not the type of person I am speaking about.
The other group are seasoned long distance shooters. Think $6,000 BR guys that have $1,000 radar units to measuring bullet velocities over the span of 150 yards shooting at 10" gongs at 1000 yards in 15mph full value gusts. Guys that are in their 60s and regularly compete in 1000 yard competition, and have been staring behind a rifle scope for the better part of half a decade. Most are educated professionals and generally keep to themselves.
On many, many occasions I have heard these folks talk about certain calibers/bullets/loads being increasingly accurate the further you shoot it.
They say that while most precision shooting is in terms of angular measurements (i.e. the MOA circle gets wider the farther you go) there are also linear measurements and a bullet's effect on the harmonics of the bore can affect the way a round travels linearly. Essentially, if you have a rifle that you fire a 1" group at 100 yards with, it could theoretically shoot a 2" group at 300 yards, or a 3" group at 500 yards. These group sizes are both smaller than the 100 yard group in relation to the distance fired whereas a normal rifle would generally fire MOA groups similar in size to what it is at 100 - normally increasing slightly due to the effects of wind and velocity deviations.
Has anyone heard anything like this? I am just having trouble wrapping my head around it, as logically thinking it out would say if you have rounds impacting 1" apart at 100 yards, if you twice that distance it is going to have to be at least 2" apart. This, to me, simply seems like a mathematical certainty.
To be clear, they are not talking about the following scenario:
Rifle A Shoots 2 MOA at 100 yards, 2 MOA at 300 yards and 3 MOA at 600 yards.
Rifle B Shoots 1 MOA at 100 yards, 1 MOA at 300 yards, and 5 MOA at 600 yards.
Obviously, Rifle A "gets more accurate" than Rifle B the further you go out. That is a separate issue.
I hope my post makes sense.
