The .257R is just right for hunting deer 0-400yds. I went from a pair of hunting rifles in 300wm and .44 mag to adding a Roberts, and lost zero effectiveness in doing so. The first couple of deer I shot with the .257 I watched the deer's reaction through the scope during the recoil and I thought "Wow that's nice". An added feature compared to the 300 wm recoil.
I've been shooting either 117 grain btsp Hornady's with 43 grn of RL19, or 115 grain Nosler bt's with 43.5 grn of RL 19 for over 15 years and I'll be happy if I never have to change it.
