.270 WSM vs. 7mm STW

I've narrowed down my search for an all purpose LR deer round to these two choices.

.270 WSM: Pros - 24" bbl, good for box blinds where room may be tight.
Cons - Feeding may be an issue. Lower B.C. with 140 grain
bullets.
Rifle will be a Winchester 70 Extreme Weather in a McMillan.

7mm STW: Pros - Higher B.C. with 150 or 160 grain bullets.
Cons - bbl life, really needs a 26" tube.
Rifle will be a M-70 Classic Stainless in a McMillan.

Anticipated shots will be out to 500 yards.

I'm leaning toward the WSM, but love the ballistics of the big seven.

I'd appreciate any input from anyone who has actual experience with either of these.

Re: .270 WSM vs. 7mm STW

Appreciating your dilemma, why not try a 7mm WSM ?
I love my 270 wsm and agree that the BC of .277 bullets leaves something on the table. My 7mm Rem mag will hopefully solve this problem for me as soon as I get it with a new 26" McGowen back from the gunsmith.

Yeah, I was thinking in the same lines with the 7mmWSM. You can still throw the heavy pills at a pretty good clip. Not near as fast as the STW, but will definitely do the job to 500yards. But between the two, I like the WSM's just for the lesser usage of powder.

I'm not considering any cartridges other than the .270 WSM and 7mm STW.

I'm sold on the WSM's. I would go for the 270. Berger makes a decent 150 that will get you out there. Hornady has that new GMX bullet that shows promise. The 150 Nosler Partition, Ballistic Tip, and Accu-Bond will do the trick. Sierra shows promise in their 135 SMK, and 150 Game King. Speer should offer some good solid hits with their 130 and 150 Hot-Cor and BT's.

This of course if you reload, but if not, they offer most of the bullets I have selected in decent factory loads. Go with the 270.

I would save the 7STW when you want to enter Howitzer status and build a rifle with a 28 to 32 inch barrel and take advantage of the powder capacity and bullets available.

Re: .270 WSM vs. 7mm STW

I own both of these rifles and here is my advise.

For DEER up to 600 yards, I would go with the 270wsm.

If there is a change of shooting ELK, or deer past 700 yards, I would go with the 7mm STW.

My 270wsm is a 24"bbl, and the STW is a 28". Neither have brakes. Another drawback of the STW is dealing with VLD bullets fitting in a standard magazine box. My loads with berger 180s are 3.840" OAL seated .010" into the lands!

Now.... If I could only have one rifle I would do it differently. I would want a 7mmWSM, or a 6.5X284. It sounds like you are dead set on these two rifles, but from My experiance...... I WOULD GET A 7mmWSM!!!

Hope this helps

Re: .270 WSM vs. 7mm STW

I would go 270 I did and am very happy. I have taken elk out to 800+ with it. (Not highly reccommended I know) I understand the availability of high bc bullets is tougher to find but they are out there. As stated above all of those are great bullets. If you dont reload try the winchester xp3, failsafe, or accubonds. My rifle loves both the xp3 and the failsafe. I am actually buying boxes of factory winchester ammo and then taking them apart and reloading with my own (magic).. Just some more to think about.
