Anyone using 6br for 1000yd prarie dogs with good results. I have done it with 243 and 22-250 with VLD bullets with more velocity than a 6br. I've set back the 22-250 to a 22br (8 twist) and love it with the heavy bullets and was thinking about selling 243 which is a Mauser switch barrell with a 22-250 and 243ai bbls since I have a 6br being done as soon as bbl comes. Thanks for any feedback.
