I never cease to be amazed at someone gripping about changing the primer feeder from small to large!
It takes all of a couple of minutes, you normally have the shell plate out to change calibers anyway, so it's no big deal! Biggest problem is making sure you run it out of the one size/type primers BEFORE you tip it over to change the disc!
:banghead:
Hands and knees on the floor picking up primers!
As for that $168, it seldom costs that much. You don't
need a stand. You don't
need another powder measure.
Look in the back of the 650 instruction book. Each part required to load a particular caliber is spelled out. You can order
ONLY the parts you need to change to another round. For instance; I already had a 40 S&W kit. I wanted to load 357 sig. All I needed was a powder funnel, tool head and dies! The shell plate was the same, since the 357 sig is based on the 40 case. The case feeder parts were also the same, as were the locator buttons, the bushing for the case feeder were the same, and the primer feed was the same,(small pistol).
The 650 loads so fast you'll need to buy a LOT more components. Buying 100 at a time is a thing of the past. One thing that makes the changeover worth it is loading a pile of ammo while it's set-up. Then changing over for the next caliber and loading a lot of it.
