Re: why not the 257 wthby
I have and shoot a custom commercial mauser actioned .300 wby, so I have some experience with Weatherby's. I believe that WBY's are a lot like the Ackley conversions....ahead of their time. When they were developed, there was not much choice in slow burning powders. Today we have so many good, slow burning powders available, that many of the older cartridges with bad reps for barrel life have received a new life. I shoot a .220 Ackley Swift for varmints that is the most accurate rifle I own. I have shot thousands of rounds thru it with little or no barrel wear. I use a Shilen match ss barrel and have crono'd my loads as fast as 4100 fps.
The right powder matched with the caliber you are shooting is as important as the bullet you choose.
