Lets toss in some information. At 300 yards both your group size and conditions come into play. If you know where to hold(IE how far your bullet drops at 300) then you also need to know how far to hold off for the wind. How fast is that wind? What angle is it coming from? Wind from 3 oclock is full value but wind coming in at 130 or so is worth half that or less for windage.

Now lets factor in say 400-600. What temperature is it? That will affect the impact height. Along with wind drift. Because it affects the MV. Wind is still a factor and you need to know it to within less than 5mph exactly and the angle of it. What about altitude changes? Barometric pressure starts to come into play. And a few other items that you have to factor in. And thats assuming you know the yardage very close. 25 yards or less. And assuming you've come to learn by actual firing at each yardage increment.

Be very careful. IT takes a lot of work.

I can be totally sure that my first round will be a center hit way on out there. Given good circumstances I have no doubt out to around 1000 yards. But it comes from shooting out to 1000 yards for 15 years and during the season shooting every weekend and practice during the week. No less than 50 rounds and up to a couple hundred rounds a weekend. Yep it can be done but it takes a bunch of work. 300 yards is a long way for most.

So you don't get scared off -- time of flight is not a big issue in shooting game. They can't move much in the time it takes a bullet to get there. And if you are shooting a mag, you are fine there. But note how many times I've said it takes practice. When I started shooting I could not keep all my shots at 200 yards inside a 12 inch circle with open sights. But I've progressed way past that with practice. And it has to be good practice. Not just shooting to shoot. You have to see progress.

Go to the site I mentioned earlier and get some info if you are serious. Then get a good rifle-- in fact I"d suggest starting with a good 308 bolt gun and learning to shoot 300 yards. Shoot and shoot and shoot. Then move out. Get involved in FClass competitive shooting and you'll be doing yourself a favor.

Good luck, Jeff

I should add the anecdote on finding long range deer. My friend used my muzzleloader to shoot a buck at 218 yards last fall. I watched and we had the hit. Went to find it on the mountainside and could not. Luckily I marked the spot we shot from and had made a bunch of mental notes as to the shot and where we last saw the buck. I still had to go back to the shooting spot and we were about 80 yards off in the search. Hand signals till he was standing at the spot and sure enough theres the hair. Still lost the trail and I had to go back again to signal him to the last spot. Sure enough he looks down and blood again. Followed from there to the buck. But most folks would not have the knowledge to mark those spots so well in the mind and do all the hiking back and forth and the work required to hit the trail and find the deer. Most would probably say-- I musta missed..... And thats not even close to long range.
