Don't get too bummed. There are lots of ammo options for that 270. I was in a similar boat as you were. Got rid of 2 rifles (one a magnum caliber) and bought a 270 and a 308. Both guns were a bit picky with ammo. The one brand that has shot consistently well out of all my rifles was the Barnes bullets. The 270 really likes the 130 TSX. The 308 shoots the Barnes well too, but the barrel gets a ton of copper fouling. I would give them a try.
The difference between try and triumph is a bit of umph!
