Why spend a lot of money because someone says a premium bullit is better than the cup and core for White Tail Deer
A cup and core 270 will work 100% of the time on broadside chest shots. It will work on 99% of all shots. It's the 1% where you need a bonded,partition, or mono Barnes type bullet.
RH makes a good point. However the way I see it is, you can find Nosler partitions at SPS all the time for cheap. Why buy anywhere or anything else????? The last 200gr. 30 cal partitions I bought from them were $13.45/50 and I took both my buck and bull last year with those bullets. I can't remember off the top of my head what I paid for the 500 150gr. partitions, but it was well worth the money. You can do a lot of practicing with your hunting bullets and loads this way.
As a matter of fact, here you (not you RH, but those that don't buy there bullets here) go:
$17.20/bag 150gr. nosler partitions I like keeping chit simple and use only this bullet in my 270. Works for anything (even elk and moose) at any sane shooting distance too...
