I am looking to buy a progressive press and would like to hear some good and bad about presses. I load for 9mm,45acp,38/357,41mag,44mag,454cassul, and would also like the press to be able to handle .223. I have been reloading for about 3 yrs. with a single stage press and want to be able to increase my production. I mostly reload 357 and 45 and want to be able to pump out a lot of good practice ammo for those calibers. The others I shoot but not on a weekly basis. I am considering a Dillon 550 or 650 as I have always heard good things about these presses and customer service. Is the 650 worth the extra money. How fast can a caliber change really be done? How much ammo can you really produce in an hour? I am also considering a Hornady lnl ap and would like to hear what the owners think about these presses. Are these presses worth the money or should I just buy 4 Lee progressives and leave them set up for specific calibers? I originally bought a lee aniversary kit but have slowly upgraded some of my equipment like the scale and powder measure. Are the powder measures on their progressives as finiky about feeding powder like H110. That powder practically locks up my Lee measure and if the progressives measure are like that I won't even bother with them. Thanks in advance.
