so what caliber shoots the flatest? I have heard .257 weatherby mag.....
7MM has some of the best numbers out there as far as hunting cartriges

im dumb and uneducated.. whats the diff between 7mm mag and 7mm 08 ???
Post by: whacker1 on January 26, 2009, 05:31:39 PM
300 RUM just a hair behind
7mm RUM is in there too
25-06 can compete
22-250 is getting pretty competitive
the balistics are pretty close between the 270 and 7 mm until you get out aways, and the 7 mm caries more knockdown power.

I think the 7 mm mag is , but I will have to check the bailistics for those two?
Post by: JoshT on January 26, 2009, 05:52:15 PM
I know you can load 120s in a 7mag around 3600... same goes for 150s in the big a$$ .300's... but you don't see a lot of that stuff on shelves. If ranges are extended to 600 or 800 yards... some of the high BC stuff would come into play... but at ranges where "flat shooting" really matters... 400 yards is probably a better standard.
I shoot 100 grain NBTs at around 3350... dead on at 200 is about 16" low at 400... that's plenty flat for coyotes... or deer. I'll have a turret for the stuff beyond that. I think any round that shoots less than 18" low... with a 200 yard zero is plenty flat... so, what do y'all consider flat?

From reading this and your above thread if I was you I would get a 7mm mag. The 7mm is a much better cal. imo then a 270.
I have both and the 7mm shoots flatter, out further, than the .270 shooting 140gr. NP out of both. :twocents:

.338-378, .338 laupa, .338 edge all with the 300gr seiara .768 BC
Perhaps the price range should be posted before we start throwing $3000.00 rifles up for him to compare to :twocents:

What ranges are you talking?
The higher BC (Ballistic Coeficient) bullet going the highest FPS will be flattest period.
In order to accurately compare rounds you need to compare equal bullet weights.
Of the two rounds shooting equal weight bullets the 7mm Mag will be flatest due to higher FPS. Going the same FPS with same weight bullets the 270 will be flatter due to higher BC.
High BC is not as important to killing animals as high SD (Sectional Density).
Starting to understand there are a lot of variables.
Also some rifles won't hit top speed without a longer barrel.
You will never get a true 3600fps out of a 7mm Remington Mag with a 120gr bullet. Maybe in a 7mm STW but not the Remington.
You cant get a true 3600fps with a 165 out of a 300RUM and 3800 with a 150. Barrel life will be the same regardless of bullet shot if all are shot at MAX + velocity. Most people would never shoot the accuracy out of a hunting rifle barrel.
Recoil is real simple on the surface. NEWTONS LAW !!!!!! Stock Design, Material, Recoil Pad, Rifle Weight, and barrel length all determine recoil. Just count on the faster the bullet is going the more recoil in general is going to be created.
If you debating a 7MM Rem Mag over a 270 I would go with a 7mm, but if you are worried about recoil then the 270. Better to hit with a 22 then miss with a 50!
Keep the questions coming and hopefully we can help you out.

The size of the cartridge and its powder capacity is what determines the velocity potential and therefore how flat it will shoot. The diameter of the bullet really isn't that critical. You can have flat shooting cartridges in anything from 22 caliber up to about 338 caliber. It just all depends on how much powder you're burning and of course along with that comes more recoil. Generally the more recoil, the flatter shooting a cartridge will be.
If you want to compare apples to apples then when you compare 270 to 7mm, you need to use similar cartridges, like the 270 Winchester and the 280 Remington. They are both based off the 30/06 case and therefore have similar powder capacity, and basically there is no difference in the trajectories betwen the two. Comparing a 7mm Magnum to a 270 Winchester is not a fair comparison. Sure the 7mm will shoot flatter but it also burns more powder and recoils more.

When you mention 270 and 7mm you aren't specifying which cartridge you're talking about. In 270 there are only a few...270 Winchester, 270 Winchester Short Mag, 270 Weatherby Mag. Then in the 7mm you've got 7x57 Mauser, 280 Remington, 7mm Remington Mag, 7mm Winchester Short Mag, 7mm Weatherby Mag, 7mm Remington Ultra Mag, and this list goes on.
You beat me to it. This is for factory guns with 26" barrels max.
The 7mm RUM is the flattest shooting out to 1000yds using a 168 grain Berger Bullet for hunting, and a 168 grain A max for targets.
It passes the 30-378 weatherby at 600 yards.
I think the big 338's (338 Lapua and Edge, and 338-378 pass them both up at 1000yds with the 300 grain sierra matchkings.

The .338 cal's start to shine past 1000yds.

50 Y 100 Y 200 Y 300 Y 400 Y 500 Y
0.6 1.5 Zero -6.7 -19.5 -39.3
7mm Rem Mag shooting 140 gr nosler accubonds at 3110 fps. Federal premium.
50 Y 100 Y 200 Y 300 Y 400 Y 500 Y
0.4 1.3 Zero -6.0 -17.4 -35.2
When both are Zeroed at 200 yards there isn't much of a difference in trajectory. The 7mm beats the .270 by 2 inches at 400 yards. Also the 7mm is only generating 171 more pounds of KE at that same distance. But the 7mm kicks more and burns more powder. To ME the .270 makes more sense. :twocents:

I have to agree with JMK, my 7MM doesn't kick as much as my .270 shotting the same 140gr., maybe its the difference in the manufacturer :dunno:

Do you reload, or have somebody who is going to reload for you?
If not then life is real simple between those two rounds. 7mm Remington Magnum
Now what is the difference? 350fps So go run some ballistics with that data to cause you even more worry.
Do you get Dirt Bike Magazine? If not go online and read the "Mr Know It All" section. You are really pushing getting the Mr Know it all answer. :chuckle: :chuckle: :bash: :bash:

Huh??? How about looking at the 308 also. :chuckle:
Low recoil, accurate, shoots as flat as you'll ever want out to 300 yards which is as far as you're likely to shoot, and cheap store bought ammo readily available in many different bullet types and weights. And did I mention it's easy on your shoulder? But then so is the 270.
Like somebody said, flip a coin. ;)

Reading all of these I think 7mm mag wins in this post.
The 7mm magnum? The 7mm Remington Magnum? The 7mm RUM will beat it hands down. Might as well go with the big dog of that caliber.

If it was me, and I was going to buy one rifle for a while it would be the old 06. I only have two guns, but if I could only have one it would be the 06. That last sentence was serious no joke at all.

Here is some info on the 7mm Rem Mag shooting the same bullet
http://www.federalpremium.com/products/details/rifle.aspx?id=375
The 7mm mag beats the 7mm-08 by about 5 inches at 400 yards with this bullet. While it only beats the .270 by 2 inches. And if you buy a 7mm-08 you basically have to handload because they don't load very many heavy bullets for it. Federal's heaviest load is the 150 hot-core.
Personally I think that if you want to get a flat trajectory without using a BIG magnum I think you should look into the .270 WSM. They don't kick very much and I has about the same or maybe slightly better ballistics than the 7mm mag. But I don't think that it will do anything that the regular old .270 winchester won't. :twocents:

Im gonna pick it up in a bit and sell it for him on here......Why don't you buy it from him? The last of the New Haven guns are gonna be worth a good chunk of money.
