I shoot prairie dogs each year and am looking to add to my collection.. I started with a Rem 700 in 223, and then a Savage Model 12 in 22-250, then Remington 700 in 243, then Savage Model 12 in 6BR. then a Remington 700 ( trued action Jewell trigger in 6BR.. So what's next? Most shots are +175 yds to 350 yds and even out to 500 yds ( rare).. So what would be next? Thanks.....
