Hi,

Im new here was wondering If I could get some info on the Model 700 Sendero SF in 7mm Rem. Ultra Mag Basically to outshoot my friends 270win savage in power and accuracy. Anyone with experiance with the rifle orthe caliber would be more then helpful.

Thanks.

A 7mm Ultra Mag is already more 'powerful' than a .270, pretty much any way you slice it. So not sure what you mean there.

As far as accuracy goes, the simplest thing to do is pick up one box of each type of 7mm Ultra Mag ammo you can find and see which one does best. Probably not a lot of different ammo choices yet.

If that doesn't yield the results you want, then it's time to start messing with the rifle's bedding, and possibly handloading. Also get the trigger adjusted by a competent gunsmith, this alone will do wonders.

A good quality scope, properly mounted, is a must.

What have you done so far and what were the results.... that information would be helpful.

Welcome, Gimpy -

Addressing the power issue between the .270 Win and the 7mm Rem Ultra Mag, let's take a 140 grain bullet to compare. Using a common slow burning powder (Alliant RX22), WLR primers in the .270 and Fed 210 in the 7mm UM,we see the following velocities and pressures: .270, 58.5 gr @ 2980 fps and 50,400 C.U.P. For the 7mm UM, 89.5 gr @3509 fps and 65,000 C.U.P.

As you can see, the 7mm UM takes a great quantity more powder and develops faster velocities with more attendant chamber pressure. These loads are maximum listed in the new Lyman 48th edition Reloading Handbook, by the way. Hands down, the 7mm UM had more power than a .270 Win.

Now, as to accuracy - that depends entirely upon the individual rifle, load combinations used and the person behind the rifle. Both rifles you mention are capable of fine accuracy. You and your buddy are just going to have to have a shoot-off to determine the most accurate shooter/rifle.

Well its common sence that I could go get a weatherby 257 or 270 and just hands down more accuracy then the 270 win I was looking for that remington shell so I wouldnt have to spend a million dollars on a load of ammo for weatherby calibers.

However still have that upper hand in performance with paying less then 50 bux a box when I wanted to shoot it.
Just wondering if that combo between the sendero SF and the 7mm ultra mag would give me the upper hand I need for accuracy after all he has a 500 dollar savage rifle with remington 130gr loads.

Cant be that hard to beat I do however know that 270 is a accurate shell of its low recoil I have no problems with recoil I handed my tolerance over to 2 shots of 460 wby mag. Let me know what your ideas are anything will help thanks.

Gimpy, Your statement that a .257 or .270 Weatherby is going to give "hands down" more accuracy than a .270 Win., is arguable. Weatherbys aren't known as much for accuacy as they are for speed. But the rifle itself, not the cartridge, is going to determine accuacy. Now, the 7mm Rem. Ultra Mag. cartridge is very fast and powerfull. Much more powerfull tham a .270Win., and the Remington 700 Sendaro is a very well made and usually a very accurate rifle. This is a grest combo, but accuracy can only be determined between a Remington rifle and Savage rifle by shooting one against the other. My guess would be, your friends rifle will group better, but you'll be way ahead in power. One more point, these super mags have a lot of power, but take a lot more pratice to shoot well. They Kick a lot more and make a lot more noise.

Accuracy has more to do with an individual rifle/ammo combination than a given brand or model. Nobody will be able to TELL you which is more accurate. You'll just have to "buy it and try it" to find out!

I agree it is a rifle/cartridge combo that makes accuracy this is the reason I chose the sendero SF in 7mm ultra mag. I just wanted to know if that rifle/cartridge combo delievers accuracy well enough will ensure easy bullet placement at 400 yards and below.

As for outshooting that 270 win that is up to me but having that rifle/cartridge is a plus reason for wanting a super powered cartridge as a long range moose and bear rifle. I wouldnt be here asking questions about accuracy. I really dont know how the 7mm preforms so I came here looking for answers from owners on the cartridge.

As for the 257 and 270 wby there is no doubt in my mind that they are some of the most accurate calibers in the deluxe and accumark weatherby models. The question here is will this make an accurate cartridge in that sendero SF rifle? Any scope advice for the rifle would be nice also.

Thank you for your posts keep'em coming.

At 400 yards there is no such thing as easy bullet placement.... sorry.... you'll have to know range and trajectory very well, and deal with wind drift also.

That's a heavy recoiling rifle you're thinking about, so don't put a cheap scope on it that you bought from Wal-Mart. Leupold is never a bad choice when it comes to reliable scopes. Need good bases and rings too, not the $5 ones. Leupold, Redfield, Warne... even the basic Weaver mount is really a pretty good setup.

Good bullets can be had in 7mm so be sure to use ones that won't blow up on impact. The cheap ones will probably turn inside-out on short range shots.... not good. Partitions, "X", Failsafe (if Winchester ends up loading for that caliber) will be your friend. The plastic-tipped bullets may be accurate and fun to shoot at the range, but don't use them in the field on anything you plan on eating.

7mm cartridges have been killing game well since the dawn of smokeless powder. The ancient 7x57 has killed anything that walks on this earth. So a 7mm is not a bad starting point for a hunting round.

Lastly, you'll need to practice a lot. I'd suggest learning to handload if you don't want to spend a ton of money on ammo.

No free lunch.... performance costs money. Good for you for asking the questions up front.
