7mm Rem Mag Vs. 300 Win Mag

[elkaholic9292]

I did, and I load 64gr H4831sc at 3000fps and consistently shoot a 2" group at 600yards. If I were shooting factory loads I may go 168gr

I follow you know. I am strictly speaking to factory loads. I am not equipped to handload unfortunately.

You can take my 2¢ for what it's worth.

You are going on an elk hunt in 6 weeks, potentially with a brand new rifle and unproven loads to shoot an elk potentially out to 800 yards.

Sounds like a recipe for disaster to me.

To answer your caliber question, my preference is for the 300 win mag.

I don't know what the twist rate is on a factory R700 7mag is but it may or may not shoot the 168 grain VLDs effectively and I highly doubt the 180 ones.

I know the 300 win mag will shoot 180s. The 7 mag only slightly eeks out the 300 Win mag when shooting the 168 or higher weight bullets.

I agree I know I am cutting it close on my time line and if I am not comfortable with the new rifle in this time frame then it will stay at home.

The 7mm Mag has a twist rate of 1:9.25 and the 300WM has a twist rate of 1:10.

Can somebody help me out here on how well each will shot the VLDs in the grain sizes above?

Thanks

7mm Rem Mag Vs. 300 Win Mag

Hey guys I have a 7mm and a .300 ultra mag. I know its not exactly the two calibers you are trying to ask about but they are pretty close. And I love both of them but I wanted to get rid of my .300 ultra cause it wounded on one end and killed on the other lol. I have a friend that is into competition shooting long range and he has turned me on to the 6.5 creedmoor round. For hunting it will do very well and long range even better. At 1000 yrds it was 260fps faster and had more kinetic energy than the .300 win mag. Not trying to down your chose or the cal. but look into it. Its a really neat round and inexpensive gun and round.

There is no way a 6.5 Creed will be faster or carry more energy that a 300 Win Mag at 1k yards.

Unless the 300 win mag is shooting light weight non match bullets.

Creedmore 140 AMAX


300 Win Mag 180 LRX

Scott Harrold with Quarter Minute magnums out of Lewiston ID built my rifle. He builds everything from a 6mm/.243 to a 50bmg, but he specializes in long range elk hunting rifles. He builds 300 win mag and 7mm rem mag with equal enthusiasm, so he didn't try to steer me in any one direction. They both have their up side and down side. I chose the 7mm mag because it did everything I needed, while not kicking the snot out of me in a he process. I'm 6'4" 260lbs. So it's not about being man enough to take it...it's why take it if you get such good ballistics with 7mm without it. One thing I might add, 1000 yard capable guns are rare, and 1000yrd shooters even more rare. Even when you have both, doesn't mean you should take a 1000 yard shot. I won't shoot more than 600 in most cases. Here are The first three shots I made with my rifle. Out to 1000k, you won't see a difference in either caliber.

6.5 Creedmoor vs. the .308 Winchester
In the first article above, Zak explains: “Why 6.5 mm instead of .30 caliber? Put simply, they sling the long, slim, high-BC 6.5 mm bullets at respectable velocity. It duplicates or beats the .300 Win Mag’s trajectory with less recoil than a .308 Win. Compared to the 175 Sierra MK fired from a .308 Win, the 6.5 mm will have 27% less wind drift and about 10 MOA less drop at 1000 yards. Despite a 35-grain deficit in bullet mass, the 6.5 Creedmoor will retain 18%more. http://www.accurateshooter.com/tacti...competition/re energy and hit the target 260 fps faster.”

Those numbers are comparing it to a 175 gr bullet fired from a 308, not a 300 win. Start reading from "compared". The part about it duplicating or beating a 300 win's trajectory has nothing to do with the numbers they are claiming.

Just stop while you're ahead. The 6.5 CM, while a decent round isn't a hot rod by any means. The 300 will stomp it all day long. Yes the 6.5 has great sectional density and BC but it's not as fast as a heavier bullet in 300. Common ballistics. 300 will beat it every day.

ok I'm telling you... CALL ROBERT... Unless things have changed they have been catching up in the shop and they were planning to have build time down DRAMATICALLY... You'll be happier in the long run...

If you still say know... this just hit classifieds

I tried calling APR a few times today but no answer, so I left a message and just waiting on them to call me back.

I did see that rifle too.

Thanks

My next load will be with 162 A-max bullet with either H1000 or retumbo
I have not hunt yet with this rifle....
