Most accurate rifle I have is a weatherby Mark 5 in 257 wby. Have a 300 wby, and 243 win in a vanguard, a howa 1500 in 338 win, and a Smith and Wesson 1500 in 7mm remington. The vanguard, howa and Smith assassinated all the same rifle. The vanguard is a good rifle for the money. As the 257 wby it will be good for the purpose you want. Remington did make a rifle in 257 wby a view years ago, so you might find a used one around.
