I shot a lot of 7 Rem Mag, frankly I see no advantage of it over the 270 Win. Using 150 gr. data on the average you can get 200 fps more out of the 7mm, but that gap lessens at range, which doesnt matter at normal hunting distanced. I gave up the 7mm after 25 years or so for the 270, I didnt think the extra 200 fps was worth the extra recoil and rifle weight.
So my primary hunting rifle is the 270 Win..
But???
As much as I love the 270, now they have better long range bullets, I'm starting to wonder.
I've been playing with the 6.5 CM. Hornady has developed the 147 6.5 bullet. Its (according to the data hornady puts out), its about 100 fps slower then my 270 loading, but thats off set when you add distance. The 270 starts faster, but when you get out there things change.
I dont hunt at 1500 yards, but use it for an example. My loading for my 150 gr. 270 has a remaining velocity of 1035 and engery level of 357 ft lbs.
Where as the 147 CM has the remaining vel of 1132 fps and 418 ft lbs of energy.
To be fair I basing this on data not shooting. I havent tried the 147 gr bullets in my Creedmoors yet.
But in the future, the Creedmoor could easily beat out the 270 and 7mm. Rem Mag.
That remains to be seen I guess. Going to have to try the 147s and see what happens down range.
