I use a Lee 4 hole turret press for quick load development. For large number of loadings I use either a Dillon 1050 or my Dillon 650. Just sold off my 2 Dillon 550 presses as I didn't use them much any more. Have a larger RCBS single stage press for heavy case forming work.
Been selling reloading equipment at gunshows for 32 yrs so I've had and used almost every brand of presses made but settled on the Lee, RCBS and Dillon.
