In a way the 257 Roberts is an ok round just like a hundred others. It's just that it's about dead.
It never caught on being a little too big as a varmint round and a little too small as a game round. It was designed by a famous and very good Schuetzen rifeman however.
The rifles the 257r. were chambered in back then were too big and heavy for game hunting with 26" barrels yet the round is light in a way and not really powerful enough. Most of us can shoot better guns.
The market has spoken and the little 257r. is dead.
