[QUOTE="James Jones, post: 222343, member: 8843"] I have used two Lilja 3 groove and two Pacnor 3 groove , both Lilja barrels shot great , fouled very little but their were is reasonably mild rounds one was my 260 the other was 300 win mag. The two pac-Nor barrels both fouled worse than the Liljas but not as bad as a factory barrel one was 22-250 Ackley the other was 243 Ackley. I know that with the two later barrels they would blow bullets up once the speed was in the 4K range both 1-8 twist. Had to stick with the V-max and Ballictic Tips for the realy high speeds. I'm pretty sold on cut rifled barrles now especialy the 5R barrels like the Rock Creek , Obermeyer and Bartlein although my next build will be on a buttoned 5R made by Broughton. I think that the more land and grooves you have makes a realy big differance in keeping bullets together at high speeds , the 3 groove barrles have much wider lands and those put a good bit more stress on the bullet which helps to break them up. For a real hot rod like your building my vote would be for a 5R from a cut rifled maker , Rockcreek , Obermeyer and Bartlein (in no particular order) [/QUOTE]
