I carried a .257 Roberts with 100-grain Partitions handloaded to about 3250 fps,
(This was sort of a Bob Hagel-level load, but not excessive in the rifle's 24" barrel.)
***Oh, and when sighted-in at 300, the point-of-impact at 100 yards was just about exactly three inches high.***

That is impressive---- especially for 257 Roberts.
