Am loading some .300BLK for my son to pig hunt with using the Barnes 110 gr bullets that have a long and pointed black tip. They are flat base so I have to use a lee flaring die to open them up for seating just a little, and then use the factory crimp die to bring the neck O.D. back into specs. The problem is that not very much of the base of the bullet is down in the case and if you lay a finished round on its side and roll it they wobble terribly. They shoot fine but he limits shots to 100 yards. How do i get these bullets to load straight into the case?
