Well I just sent the payment for my Defiance Deviant action! I am building a 300 RUM, 1000yrds is my goal and I would like to get the barrel ordered since it seems that will take the longest to obtain. I have chose to go with a Broughton 5C barrel 28" finish length and I plan on having it fluted. I would like to keep the barrel weight around 6lbs and I think I like the heavy palma contour Broughton has.... but I want as much rigidity as possible. Is this a good choice on contour for a rifle that will be a target/hunting rifle?? Also I plan on shooting 210 LRAB or Berger vld's is the 1-10" twist the correct twist? Might have to shoot lighter bullets occasionally. I really appreciate any guidance offered. thanks!
