I am new to the forum and would like to ask a few questions. Seems like this place is full of information. I ran across a Back Country .257 Wby the other day and was considering the possibility of making it my go to gun for coyotes, deer and antelope. I know there has been alot of conversation on barrel length and velocity between a 24 inch and 26 inch tube. Any knowledge and actual data that shows a considerable difference? If so, would you consider replacing a barrel and what would be recommendations? Next, My overall goal would be to set this gun up with a Leupold VX-III 8.5X25 LR scope that could be dialed to yardage of 500 to 600 yards on antelope and also have the capability of messing around shooting targets of 800 to 900 yards. What bullets would be of recomendation? I have reloaded a friends .257 for a little while and have had success with RL22 and 110gr accubonds. I am thinking about the possibility of using Berger 115gr VLDs and RL25 or IMR7828. They seem to have the highest BC for .25 cal. Anyone have experience with Bergers in a .257 WBY? Or has anyone played around with nosler BT 115gr? I know seating depth can be an issue with Bergers and WBY's in general. What would be a recommened seating depth for a WBY with Berger's. Maximum length that fits into the magazine.
