The 7mm Rem Magnum although a good round does not have the knock down power of a big 30 cal magnum. The 7mm shine nicely as a flat shoot cartridge when running a 140 grain at 3200 fps for antelope and deer. I've seen elk shot with 7 Rem mags and they required more than one shot, understandable shot placement is crucial and they would have died from the first shot but they just stood there ready to takeoff, I don't know how many of you have chased elk after being hit but they can go a looong way on those legs.

A big 30 cal just seem to 'kill' them and knock them down. As far as deer it's a bit much and a 300 win has ruined alot of venison when 150 grains are used.

That said I own three different 7mm rifles and nothing kills deer like that 7mm-08 w/145 grain Speer hot-core over WW760 powder. I 've killed over 59 whitetails w/one shot w/ this cartridge and it is my go to rifle every opener here in the Pa. woods.
I've taken lots of caribou w/ both of my bigger 7's Rem mag and my 7STW. I think the 7 STW has the speed to push those 160's to kill elk like the big 30's, I'll find out next year hopefully if the man shines upon me at 10,000 feet.

There is just something magical about a 30 caliber 200 grainer going 3000 fps.

I own both a 300 Win and a a bigger 30 built on the 8 mag case. That bigger 30 will push a 200 at 3200fps, speed does kill!

Just for reference take a 30-06 w/180's and the 7 Rem mag w/175's to the range w/factory ammo (out to 300) and compare, interesting.
Just my 2 cents
