My thought process on going with Lee 4 hole turret press and the Lee 4 die Pistol set.
Presently loading on a Lee single stage with Lee 3 die rifle dies in .223 and .308. Couldn't be happier with the equipment. I have loaded on RCBS press and dies and see no difference. Looking at the necessity to load about 200-300 rounds a week, maybe more on occasion, I decided a more efficient setup was needed.
Presses: Candidates were
1. Lee Pro 1000 progressive press. This is a 3 hole press. Price wise it comes in at around the $130 range. It does come with 1 set of dies in your caliber choice. Has the case feed attachent, disk powder measure, and on press primer both large and small. Can be changed over to other calibers by adding another shell plate and dies. Does accept the Lee bullet feed attachement and increased volume shell dispenser tubes. According to lee volumes that "can be" obtained with all the bells and whistles is 300 per hour.
2. Lee Loadmaster progressive press. This is a 4 hole press. Price at around $225. All other options as with the 1000 with claimed volumes at 500 per hour.
3. Lee 4 hole turret press. Price at $75. Dies, On press powder measure, on press primer are an option. Does not support case feeding or bullet feeding. By adding powder dispenser and on press primer, a set of dies and the price is about the same as a 1000. Again volumes claimed is 250 an hour.
In going with the turret my primary reason was setup with keeping tuned. Volumes and price were NOT a consideration. It reading reviews and watching videos of all three there seemed more PM on the progressive units than the turret. Change over to other calibers was simpler. All in all the turret looked to be more sturdy in its operation.
Dies: The Lee 3 die pistol are CARBIDE. Crimping is done in the seating die. IF the case needs to be full length sized an adjustment may be required on the die.
The 4 die set contains the same dies as the 3 die set with the addition of the Lee Factory Crimp Die. This is to perform crimping and full sizing as a seperate function apart from bullet seating. The FCD has a carbide sizing ring at the bottom of the die and if the case is out of specs it will do the job. If the case is OK the ring will never touch the case.
These are my opinions and thoughts. May or may not satisify alls requirements. And I could change my options as I progress. I have already decieded to swith over to the Lock ring die bushing from the standard bushing on future dies. I will start with OFF Press priming and dump my powder case by case from my on bench measure. Time is really of no importance and I feel I can load 300-500 rounds in a good day once I get up to speed.
