This is not to start a red vs green vs blue thing
Had a long talk with an Alliant powder rep who is also a competitive shooter at the local gun store. He uses an RCBS pro 2000 with the auto index and highly recommends it over the Dillon 550 and Hornady LNLAP.
If anyone uses one of these units are you happy with the 2000 ? Do you like the strip primer system ? Can you easily deprime and re size in the same run as reloading ? Is there a roller handle available. Change over time ? How much effort to pull handle with a full shell plate of pistol brass ? OAL variation ?
I will be in the market for a better progressive soon and I have been happy with all the RCBS gear I now own.
