reading the threads an have the same rifle in 243 [700vls] i asked a friend who has shot 600, 900 an 1000 yrds about a .243 making the distance [1000yrds], he gave me some in site on it
, but keep in mind he said " if your goal is building a rifle why not do a .30-338 an make it worth while", anyways here are
some number to look at, they may or may not be 100% accurate, but are close to, as i have read
1000yrds vel 1314 - poi 344.45 drop 385.71 tof 1.59 403 drift 87.78
105 gr hp bc.497 at muzzle 2800fps drift 10mi 90degrees scope 1.75 over bore/site in 100yrds
came off a reloading comp.chart scale
6.5~20X40 sf lr Leupold scope only has approx. 330. inches of moa, so you would need a special angle base mount for the scope
the trick is speed, keeping the bullet above 1088fps so as it doesn't drop sub-sonic
a Remington 700 hb 26".243 is capable, but you'll need lots of good equipment starting with a practice times 10, an
a good trigger job or a jewel or an alike type trigger system
