In my opinion the Roberts is easy to load for. Or maybe most .257R users are easy to please. It's one of my all time favorites for deer and such. My current .257 is a custom job on a Montana 1999 medium length action which allows for a 3" OAL and I like that. The various 4350's and the newer equivalents are your friend. My rifle seems to prefer 100gr bullets over the 115-120's, through not by much. The bullets that I have the most experience with are: Nosler's 100 and 115gr BT, and the Hornady 117gr BTSP. My rifle has a 22" Pac Nor barrel and I can count on 3000FPS with the 100gr Nosler and just under 2900 FPS with the heaver stuff without torturing my cases or the rifle.
