Not the two weights you're asking about but I have tried the 220 gr. Sierra round nose in a .308 using W760. Interesting results as velocity was just shy of 2400 FPS and accuracy was sub MOA. Thinking it was a fluke I tried the load again on a different day with the same results. Dunno what I'd use the load for but it was something I was curious about.
