Most of my reloading life I have used a RCBS Rockchucker and a Redding T7 turret press. Almost all of my dies are Redding. They do the job well in my experience, however I have never really gotten very low runout. Ok, but not great.
About five years ago I ordered a Prazipress 120mm, and a set of Triebel 1 1/4 inch dies in 7x64 Brenneke. Treibel requested that I send them the exact bullet that I would be seating in my 7x64. In this case it was a Nosler 160 gr Accubond. They contoured the seating stem to match that bullet precisely. Anyway my runout has dropped remarkably, so much so that in most cases it’s very hard to read. I doubt the press reduced the runout but it certainly works well with 1 1/4 inch dies, and the pleasure in using it, is worth every cent to me. I now just use the Redding T7 for primer decapping and bullet pulling duties.
