In short range benchrest (mostly 6ppc) we used a very long drop tube and poured the powder slooo owly. to get 30+ grns in a case that most could only get 28 gns. I had a lot of neck tension and did not compress a whole lot. The neck tension kept the bullet from seating any deeper. Some sooters would use light neck tension and let the bolt finish seating the bullet with a lot of compression
