That 90 gr Sierra is the most accurate bullet I've ever shot through my .270 and it's instant death and destruction on coyotes.
It's all I used back in the late 60's to mid 70's, as a varmint, coyote tool. I pushed it with a book charge of IMR4350, IIRC.
Might have to look that load up in my notes.
It doesn't need to be run hard and makes an excellent practice load.
