Those are perfect if you have a short action .257 Roberts. I don't, but I try to keep a small pile of .257 bullets on hand so I ordered some of these a while back. My M77 Roberts doesn't shoot anything great, but seems to shoot everything fairly well. I've tried everything from 60gr RN meant for the .25-20 up to 120's. One of the best shooting was a load for coyotes 75gr Hornady HP over IMR4064. Partitions all shoot just a little over an inch.
