I'd use a 375 long before using a 270. A 270 should use a 150 premium BTW.
I'd use the one you have the most experience with, before judging based on bullet diameter, alone.
And, I wholeheartedly disagree with the "need" for a 150 gr bullet in .270 Win. Going heavier doesn't make the bullet any tougher. Some of the best bullets we have available in .277", can (also or only) be found in 130 or 140 grain weights.

If you compare the ballistics of 130, 140, and 150 grain bullets of similar shape (to prevent a massive change in ballistic coefficient), they all end up producing very similar figures. (Realistic velocities of: 130 gr @ 2,950 fps, 140 gr @ 2,875 fps, 150 gr @ 2,750 fps.) Downrange energy is within 100 ft-lb at 400 yards. Muzzle energy is nearly identical (within 68 ft-lb). And, there's less than 1" difference in point of impact at 400 yards.

Cornbush and I can both attest to incredible performance on Elk, of properly chosen .277" bullets... none of them weighing in at 150 gr.

I see no reason to increase recoil, when the 130s and 140s work just fine. Choosing a bullet of proper construction, in my opinion, is far more important than its actual weight. If weight mattered, Barnes would still be making lead-core X bullets for everything.

If you really want a heavy "premium" for .270 Win, you should step up in weight all the way to the 160 gr Partition, or 180 gr Weldcore. Then you'll see some different ballistics, and have the recoil to remind you of it.


Kraig... It's not over kill. It's just a bigger hole.
