I recently got back into reloading. Purchased a LEE Breech Lock Kit along with .223, .40 LEE Dies. I loaded a good amount of each caliber with good success with only a little hiccup of resizing/deprimming .223. At first it was stuck cases(later to discover that it was my lack of case lube), but I broke the tip of my Decapping pin and had to purchase a new Decapping rod. One Friday I had a need to load 9mm to go shoot at my local range. Searched a few gun shops for the LEE 9mm die set with NO luck. I decided to bite the bullet and purchase a set of RCBS 9mm die set. Upon setup, I notice that the Decapping rod was threaded into the die which would eliminate the slippage that I sometimes suffered when deprimming .223. Then I learned that the seating and crimping was done in one step rather than 2 (MORE efficiency). So I started loading my 9mm for my weekend shoot. I loaded about 200rnds, testing every one in the barrel of my SIG P226. I ended up not being able to make my shoot that weekend so I was not able to test fire any 9mm. I decided to purchase RCBS dies from this point forward. I have since added .38special & .45ACP die sets along with a .223 resizing die. I have also purchase L.E. Wilson Pistol max Gauges for each caliber. I have now loaded 200-300 .38 and more 9mm with RCBS dies. Gauged them(with fitment issues), readjusted, regauged(with better results), readjusted. It seems like when I resize my shells they drop into the gauge perfectly, however when I seat/crimp the bullet the cartridge doesn't fit into the Guage. I remove the Decapping rod from resizing die and run loaded cartridges through resizing die, they fit into gauge, but taking ammunition to the range for testing, the bullets now move inside the shell. I have yet had a single issue with .40 &. .223(loaded with LEE dies). Am I doing something just off the wall wrong or is the quality of Newer RCBS Dies questionable?
