Thread: 300 win mag or 7mm Rem mag

Hi guys I'm after a new stalking/medium range rifle . I really like the look and feel of the tikka t3 super lite but I can't decide on 300 wm or 7mm Rem . I will be shooting sambar deer and fallow deer . Which case would you get and why.
Cheers Tall Timber

For sambar you would probably want to go 300 win mag. Which ever one you get replace the recoil pad with a limbsaver.

I would go 300 win mag. 30 cal is better than 7mm in my opinion

Either or for the Sambar.. for the fallow i invest in rifle number two

I suspect that a 300 winmag will make a hell of a mess of a fallow deer.

Nah big 180grain bullets will just punch a hole straight through. Hollow point 130s are another thing
7mm Rem mag will also make a mess with light HP projectiles.

Having had both - id recommend the 7 due to comfort of use

7mm Mag will do the business, less recoil than 300mag, factory ammo for both is around the same for both with 7mm being slightly cheaper. Reloading would be no difference in cost but 30 cal has larger range of projectiles however seating depths for heavier pills in 30 cal can be an issue. How much mess a bullet makes depends on the selected pill at a given distance.

The 7mm with a 150 grain bullet has a sectional density of .266, a .30 cal. with a 180 grain bullet has a sectional density of .271. The Ballistic coefficients are basically the same. In other words these bullets will penetrate about the same and have about the same trajectory if the same type of bullet is used and they start out with the same velocity. The .30 cal. is a bigger diameter and is heavier, which means it will have a little more punch. The 160 grain 7mm(sec. density .283) is even higher than the 180 .30 cal. which means that for a given bullet and velocity will out penetrate the 180 grain .30 cal. The .300 starts to pull away a little in terms of power when you step up to a 200 grain bullet. The 7mm Rem. Mag. with a good 160 grain bullet and the .300 Win. Mag. with a good 180 grain bullet can both be pushed to slightly more than 3000 fps and are so close in performance that I doubt anything you shoot with either will ever know the difference.

Thanks guys has anyone used the hornady super performance ammo in 7mm they say 200 fps faster. Dose that sound right

Possibly, because most 7mm rem mag factory ammo is loaded down for some reason. What velocity are they quoting? I used to get 3070fps with handloaded berger 168gr out of my 26" barrel 7 rem mag.

Hornady are saying between 3070 and 3200 with the 162 g sst

Rate them, granted my mate and I havent put it through anything as yet, but was bloody accurate and was highly recommended by a number of people.

Thanks for all the replies guys. I'm planning on changing the stock to a manners I think so that will add a lite bit of weight . I'm planning on making a trip to NZ from over here in OZ one day , what's the go with bringing ammo on the plane or would I just buy factory ammo when I get there. Cheers
