Both real good choices. My Dad's favorite was a Jack O'conner pet load. Lots of IMR4350 and 115-120gr Nosler Partitions, 117-120gr Hornadys, 117gr Sierras, 125gr Barnes (hard to find) Velocity on the heels of 3000fps. It's worked in both our Remington Model 722's in 257Roberts. I can't break 3000fps in ours unless I drop to a 100gr and those 100grainers will break 3100fps easily.
It's a fun cartridge and has worked for us since 1952.
