Does anyone have favorite loads for the .257 Roberts? So far, it looks like Speer 120s Nosler Partition 120s, and Sierra 117s are the most reliable and accurate. I never could get SST 117s to shoot very well. Combined Technology 115s pattern, and the 100s just don't impress, so far. Looking at a ~3/8 in. load from the Sierra 87s tho.
I use IMR 4064 for the 87s, and I may try Nosler 85s just to see. H4350 and H4831SC for the 100-120s. Has anyone had experience with any 75 gr. bullets? How do they tend to shoot? Are they not too short?
Thanks.
Thanks.
