I have a 257 weatherby and a 30/06 and I like muzzleloading also I am suprised that the 30/06 doesnt feel like a 220 swift to you going from black powder I can understand your reason for wanting a 257 obviosly I have one. If I had the option to repurchase I might go the 25/06 route. The reason is I reload and brass for the weatherby is a buck a brass. The 25/06 can be purchased for about 14.00 for 50. If you plan on buying your cartridges it is not all that different. I buy the 31.00 100gr. wby. if you purchased a box of similar quality 25/06 your about 26.99. I hope that is helpful.
