I'll give it to you for 300yds. It's using a 150gr Hornady BTSP with a bc of .349
and a vital zone of 8".

Max PB range 340yds Bullet 4" low
Max PB zero 293yds
zero @ 100yds +3"

150yds +3.9"
200yds +3.6"
250yds +2.3"
300yds -.5"
340yds -4"

Now I find it a good idea to check these figures with actual fireing at these ranges. Without a cronograph you can't be sure of what your velocity is in your rifle. Indeed in my rifles I seldom get the same average velocities that are listed in my books.

Muley Crazy,
That .300 win mag is capable of pretty long shots, in fact it's far more cabable of longer shots that most of it's shooters are. Just curious though, are you planning on using this for hunting? If so, then are you capable of making shots in the field beyond 400yrds, without a benchrest from all shooting positions? What about even 200yrds or 300yrds without a benchrest. Something to think about. If you can't, then don't worry about what the bullet drop will be beyond 400yrds. It doesn't matter. If you can't put all your bullets inside the area the size of an 8" or 9" circle at a given distance, then it's not ethical to attempt it on a game animal in the field. My general rule of thumb is that if you can't get within 200 yrds of any game animal, then you need to re-think your hunting strategy.

Military Snipers who use the .300 Win Mag for competition shooting also use a bipod on the range. These men and women are great shots but they are only capable of and required to hit somewhere within the area the size of a human torso beyond 600 yrds out to 1000yrds. That's a pretty large area of error for a bullet to hit and it just doesn't cut it for hitting the vital area on a game animal and making a clean humane kill. For that you need to hit inside of an area that is no larger than the 10 ring.

If you are talking just plain benchrest shooting only, well then forget what I said and have fun shooting that thing.

I understand your worries about some clown trying to shoot a game animal far beyond there abilities. Some areas out west require shots out to your personal abilities. and if 200 is were you feel comfortable that great !!

Here's a link to Long range Ballistic software you can download Free for 30 days.
I've not used it as I have no need, so I can't verify its usefullness or accuracy

http://www.ballistics-software.....tables.htm

If you don't want to download it, I just might give it a go !!

I downloaded the program. It seems to work pretty slick. Easy to use. Information comes out the same as my sierra manual. Kinda neet how you can enter all the info for diffenent loads and guns and safe it with comments. Might be usefull to keep track. Prints off pretty good targets too. Easy to find out how much a bullet drops at any distance. Thanks for posting this address.

The web link specifically mentions Hornady AND Winchester. The info should be there.
It was the only free software package I could find. If you can find the same bullet type in Remington or others,I'll bet the differences would be at best only a couple of inches.

I found your bullets exactly as you stated in your first post. click on the load button then click find. You can find tons of ammo there. Winchester XP3 300 winchester at 3260fps. Then you can add your gun and it will tell you how to try to shoot it at those crazy distances you want. Works really well as compared to other charts I have. I can shoot really well with program, hope I can get 1/2 this good in real. Kinda neet you can do scenerios where you shoot up or down hill. Gives a good mental picture of how a bullet travels. Happy shooting.

Those ballistic tables are fine....for getting a 'general idea' about what kind of performance might be rendered from a cartridge/rifle but in the finality.....it won't possibly be correct due to the fact of barrel harmonics! The barrel 'whips' just like a fishing rod and a bullet may be exiting the muzzle on an 'up node' or 'down node' of vibration so the only way to tell what a rifle/cartridge/load is doing is to zero from wherever and then shoot at the various ranges! :lol: :o

The ballistic tables and data print outs are fine and dandy and will get you pretty close BUT the best way to find your "dope" out is to go out and shoot it at distances you want in a controlled enviornemnt. A gun is like a finger print, no two are a like.

I suspect that you are going to do the laong range thing so here's something to think about. You have asked for info out to 600yds. Here's what your bullet selection costs you at 500yds:

150gr @ 3300 fps 190gr @ 2900 fps

remaining velocity/energy

1981/1307 2026/1732

This compares a 150gr Hornady spire point to a 190gr Hornady spire point.
you'll notice that at 500yds, the 190gr load that started out slower has now passed the 150gr load and the energy level of the 190gr load is walking away from the 150gr load.

Long range shooting requires attention to many details, including the choice of bullet to maintain velocity which in turn effects trajectory and remaining energy. The heavier bullet should also in theory be less effected by wind to reduce wind deflection. For that lesson, I would turn you back over to Chester Golf or RMulhern,,,,,,,,,,,,Rich or Rick?

Although it is not a Winchester chart, the Federal chart will take you out to 500 yards and for most purposes they would be to close to notice a difference.

Simply check white boxes on left, for two choces scrool down and click compare
Bullet choice becomes paramount once you get out much past 300 yards.
