Hi there, my 50cents worth (as i get all my newbies at range to do this).
firstly understand what sight line you have, IE scope or open and find mid sight line and then distance to centre of bore (most scopes will be 30-50mm higher than bore so say 40mm) HALVE THIS so 20mm and that should be where yr bullet should hit at 25mtrs. IE 20mm LOW,,,this is for all calibres firing at 2,400FPS or greater. DOES not matter what wonderful calibre you have or think you have.
this will put you @ 30-50mm high at 100mtrs and back down at bull at somewhere close to 200mtrs.
PLEASE use a very good rest and use 3 shot groups and take centre of group as impact point. You are trying to sight your rifle not worry about how wonderful your shooting is, (thats another whole topic).
PLEASE use same ammo for sighting in as what you shoot with and if using a can use that for sighting as well. whatever you take into the field is what you use for sighting in.
Then anything you see out to 250mtrs point and shoot. if its further away you will normally have time to work out distance and then you should in interests of animal and ethics get distance correct if taking a long range shot. (burris eliminator does all the hard work here or get custom turrets, realise thats not for all....). please dont take pop shots at animals at long distance unless you know you can hit them...
