I Recently Just Received A 257 Roberts And Don't Know Much About That Caliber. What Is The Public Opinion On The Caliber? What Type Of Game Would You Fill Comfortable Hunting With It? And Does Anyone Have Any Loads That Are Accurate, If I Decided To Reload? Powder?bullets?ext?

How Do You Think It Compares To A 243.

Thanks

My grandfather has one but I don't know the manufacturer becouse he will not let anyone touch it. He has always said that its a good gun but he now uses a 30/06. Most of the time I hear about it from other persons, they also give it good reports.

Ballistically when loaded with 100gr. bullets it will have almost exactly the same power and trajectory as a 243 loaded with 100gr. bullets. So fill free to use it on anything you would use a 243 on.

The .257 Roberts is between a .243 and a .25-06 ballistically. It's reputed to be a great deer caliber, especially with the new +P loads available now. Extremely versatile if handloaded, but there's not much variety in factory loads.

Ned Roberts necked the 7X57 Mauser case down to .257 to create this caliber. In my opinion, chambering short action rifles for this cartridge is what helped it's demise. Long action rifles allow the handloader to seat 100 grain bullets out far enough to take full advantage of case capacity.

The .257 is an excellent cartridge, one of the first "dual purpose" cartridges to come into existence. With the 100 gr. bullet, it works well for antelope and deer. Lighter bullets work for varmints. It also is a light recoiling caliber, well suited for smaller sized shooters.

Selection of factory loaded cartridges is slim, you would get the full potential from this cartridge by handloading. To start the ball rolling, I would recommend the Hornady 100 gr. Spire point, and IMR 4350 powder. There are lots of excellent .25 caliber bullets on the market, Hornadys are relatively inexpensive and good quality. Your rifle may shoot something else better, but this is as good a place to start as any.
