Pretty close. The 7mm Rem Mag has a .532" and the 7WSM has .535", close enough that I think you can get by without changing the boltface. If you buy the 7mm Rem Mag, it will either work as is, or it is a 5 minute fix on a lathe.

Get the cheap Savage at Walmart and then upgrade it with a heavier barrel and stock, you will be happier than a pig in @@@@!

Re: 308, 7mag,or 300win.mag need help deciding

Of the 4 choices you mentioned My vote would be the 7 WSM "BECAUSE"

1= The 7 WSM is equal to the 7 rem mag in horsepower.

2= The 7 WSM will work in a short action making the overall length of the
Rifle shorter with a 24'' barrel as apposed to the long action required
by the 7 mag or the 300 win mag.

3= The 7 WSM has better ballistics than the 308.

4= Also the 7 WSM in a 10lb rifle produces 19.1 ft/lbs of recoil (Compared
to 27.7 ft/lbs recoil of the 300 win mag in a 10lb rifle and 24.1 ft/lbs of
recoil of your 270 win in a sporter weight of 7.5 lbs).

5= The 7 WSM also works real well with a 160gr accubond for ELK and the
140 works well for deer size game. And if you want to get crazy you could
use 100gr or 120gr and get 3400 to 3500 ft/sec velocity for varmints.

Just a few comparisons.

But he could use the Long action Savage and swap the barrel to a 7WSM, enabling him to load long bullets and still magazine feed them.

I agree with A.J., go with the 7 mag.

I see a little more fps with the 7rm and there is way better brass(norma).

Thanks again, Will buy the 7mag and play with it for awhile. Will add some weight with a good stock and barrel. Want the long action so I have the choice to go with the 7wsm and load longer rounds in the future. Had no idea just how much weight will reduce recoil (thanks JE Custom for the comparison). Currently have a 270 Ruger Mark II stainless synthetic with Pachmeyer decelerator pad. If I can even come close to this recoil with a magnum (by using a little more weight and a better stock) I will be happy.

Re: 308, 7mag,or 300win.mag need help deciding

I have hunted with a 7mm Rem Mag most of my hunting life and it has been a great gun and always got the job done. Farthest shot was 425 yds (paced off) on an antelope. Shooting it on the bench was ok up to about 20 rounds and then I would get recoil sensitive. I never felt it in the field.

I have just swithched to a 300 WSM, Sako 85 finnlight, and took it out shooting for the first time yesterday to begin load work and barrel break in. I only got 4 shots fired and decided to pack it in due to tech difficulties including a malfunctioning chrony. The rifle weighs 6 3/8 lbs and NF scope another 2 lbs for 8 3/8 lbs total weight. The Sako recoil pad is so-so and I put a slip on recoil pad for the bench shooting anticipating about a 40 round day of shooting for load work. My first 4 rounds were starting loads about 4-5 gr from expected max. The recoil was much lighter than the 7mm RM of about same total weight. And with the slip on butt pad, very little felt recoil. More than a 243 but less than a 270. These were light loads. I'm hoping to get it back out shooting today.

Sooo.... if it's not too late, I would recommend a 300 WSM. It will get you a little more range and a little more authority down range. I base down range killing effectiveness on bullet terminal opening performance velocity which is typically around 1800 fps. A few of other things to consider are momentum, SD and size of hole. If you can kill a mule deer @ 800 yds with a well performing bullet, then you can kill an elk also, provided you are not trying to smash through a shoulder. IMO, the 7mm's will be very iffy for reliable performance @ 800 yds based on ballistics charts. The 300 WSM is a good 800-900 yd rifle depending on velocity and bullet performance. And recoil can easily be dealt with. If I get a chance to get back out today I'll report back on the results.
