LEE PRECISION - .400 Cor-Bon Full Length Sizing 3-Die Set Steel

Good products in good shipping time

the biggest question on this caliber is if the resize die will resize correctly. Lee has done a good job with these dies with the exception that the powder die expands the case neck too much. i just backed it out a few more turns, but it would be better if Lee just included a short charge die with this set. FYI the Factory Crimp Die die is an absolute MUST for this cartridge

I was looking for a deal on these dies and decided to forego a Hornady or Redding die set and wish I had. While the price for what you get in this set is great, as it comes with a nice powder scoop and the shell holder. The resizing and crimp dies seem fine with no issues, but the seating die seems to only be made for basic ball FMJ .355-.356 bullets. I was making my first dummy with Hornady HAP 125gr bullets and it does not seem to contact them securely, sometimes seating the bullets in an offset cant, often leaving imprint rings around the nose of the bullet. It probably works fine for ball, but if you are going to be loading anything other than round nose bullets, you are going to be doing a lot of pulling. Lee does make seating stems for other bullets, but these cost more than the die set and take 4 weeks to order. I ended up just buying a Hornady die since it was cheaper in the long run. The loading data included with the dies set is also pretty basic and missing a lot of the powders I plan to use and doesn't have a good selection of bullet types. It seemed to be there as a brochure for more Lee products to buy. The price is unbeatable, but you are really going to be limited in what you can seat with this set.
