Doesn't this show that the 338 win mag is perfect for long range?

    Compared: 300 wm, 338 wm, 30-06 sprg.

    300 wm:
    Ammo used: Winchester xp3, 180 gr
    Muzzle Velocity: 3000 fps
    Ballistic Coef: .527

    338 wm:
    Ammo used: AccuBond CT, 225 gr
    Muzzle Velocity: 2800 fps
    Ballistic Ceof: .548

    30-06 sprg:
    Ammo used:Winchester xp3, 180 gr
    Muzzle Velocity: 2750 fps
    Ballistic Coef: .527

    (i picked the ammo that had the best BC in each of the ammo)

    Picture 127.jpg

    Picture 128.jpg

    The above pics show the bullets on the "target" and the conditions in which we shot in.

    The pics below show the data: from 100-500 yards in increments of 100: time, drop, drift, and velocity.

    Also consider that the 338 WM is a 225 gr while the 300wm and 30-06 sprg are 180 gr.

    At least for me, this shows that the 338 is definitely an all round cartridge, carrying everything between 180gr to 300gr + having long distances capabilities

    It clearly shows that the 338 winny is better than 30-06, while i dont have the ballistics calculated for the 338 wm in 180 gr my "guess" is that it would be pretty darn close to the 300 wm. what do you think?

    The problem is you are comparing apples and oranges. The .300WM and .30-06 w/ the same bullet would be a true test. Each has there place, and the .30-06 in the hands of a skilled hunter will yeild the same end. Cartridges change every few years. That is, what people view as the best. The .30-30 ruled supreme for years, then w/ cheap military guns offered in the 1950's, the .30-06 jumped in. A few years ago it was the .280(resurected) and .260 which re-invented cartridges that already exist. Having a cartridge that can take game at further distance is not always better. It tends to make anyone think they are the ultimate marksman when in reality they are not capible of shooting those ranges, nor is their equipment. Buying a $350.00 Savage .338(nothing against Savage) and slapping a $200.00 Bushnell scope on it does not make one good. I get a kick out of 50mm objective scopes also. Shooting distance takes practice, lots of practice. So here is a question. 2 friends buy rifles, 1 a .30-06, the other a .338 mag. The .30-06 costs half the amount to shoot. Both have $200.00 to spend on ammo. In the end, who do you think will be the better shot?

    jpattersonnh: you got me thinking, but my point through this thread was just trying to show that given practice and good set up, the 338 is on par, or even better, than some of the "best" long range cartridges.

    The .300WM and .30-06 w/ the same bullet would be a true test. Please explain, because im not sure what you mean by it, do you mean the 338 wm and the .30-06? because i was using xp3's in 180 gr for the both 300 wm and .30-06.

    Thankyou, for better instilling and making the ideas concrete of actual hunting vs shooting animals. i only took one long shot while hunting and gotta lot of "fun" talk from my dad and gramps. But again the point i intended for this thread isn't that .30-06 is a bad cartridge or that 338 is best. Just wanted to show that .338 with a lot of practice and good setup will get you out there with the long range cartridges perfectly.

    Your example of the two friends, either one could be a better shot, with practice and setup, and i get the point haha. I'm not sure how the money of the cartridges play's into who the better shot is, but yes the .30-06 friend would have gotten more bang for the buck...literally. But i don't think the cost of cartridge plays in too much, considering that you dont limit yourself to $200.

    Jpattersonnh, you also brought out a nice point about the changes in the cartridges every few years, i haven't really ever given that a thought. I still stick with the 338 being a better cartridge, and would carry itself better than .30-06 given that both the people shooting it have about the same experience and setup.

    You really cant compare two different calibers w/ different bullets. A 7x57 and a 7-08 would be easy using the same bullet. A .30-06 and a .300wm is easy, but once you add 45gr and .03" it is no longer a fair test. The data on the ammo you posted is also flawed. The BC of a bullet changes w/ velosity. It is not constant. The longer the shot, the more all forces play on the trajectory. So as the bullet looses velosity, the BC changes. The data you have shows the 180gr having the same BC in both calibers.

    About trigger time. If we both did have a limited budget and I shot twice as many rounds down range. Do you think I would know my rifle, my scope, and my abilties or shortfalls a little better? If I shot twice as many rounds, would that not be more experience? Also if one shoots from a bench, is that a good gauge of the shooters, or the rifles ability.

    It is really not about what caliber you shoot, just what you can do with it.

    Wouldn’t a better comparison for the 338wm be the 338 lapua or even the 340 wby? :confused:

    Even a 9.3x62, one of my favorites!
    250gr at 2600fps w/ 3726fpe. I prefer the 286gr banded solid or Partition at 2400fps, 3621fpe and 2770fpe at 100 yards. I'm going to Africa some day. BTW, Bullet is .366".
    My lowly 9.3x57 is a great rifle for bear, or other things that may bite back. 286gr at 2100fps is only 2827fpe, at 100 yards 1800fps w/ 2086fpe, at 200 1546fps and 1520fpe. Bullet drop at 200 yards is 5" with express sights.
    I love to get up close, that is a thrill.
    I found that in my youth, when I was dirt poor living on my own in Colorado my best animals. Took them w/ a Mossberg 12ga slug rifle in the early '80's. I thought I needed a .30-06, could not afford one. Bought a sportered 1918 GEW '98, still in 8x57 w/ a Lee receiver sight and fell in love w/ the cartridge.
    I then bought a Savage 110 in 7mm Rem Mag. Thought I was it. Well I'm a tracker and stalker, so the 1st time I shot a Whitetail w/ a 140gr Ballistic tip at less then 100 yards, it blew up on a rib. My rifle changed, my style had not. Now mind you, I've shot competition since I was 10 years old. I was not happy. So I needed to take shooting distance and incorporate the rifle and hunting. It worked out fine after that. I have gone back to hunting shorter distances now. I can still peg a soda can at 400 yards plinking, but I no longer find a trill in hunting that way. I have a double fusion in my neck, bad knees, bad/blown tendons in my right foot, but stalking still comes easy.

    Wish you the best on becoming the great white hunter. I'll stick w/ my old low pressure rounds. My 7mm still comes out for some distance practice at times, hell I have 700 bullets to reload for it! ;)

    Yea the 300 is flatter shooting than the 338. Both be good at long range but which bullet will make it their faster.
