I have a used lee pro 1000 for my 45acp and it is accurate in dispensing powder..at least the Bullseye powder that is all i use
in my 45acp...1 round every 4-5 seconds ..i do have to manually install the bullet.
That is cheap and this thing has loaded over many thousand rounds before i got it..and has done a few thousand for me just this year..
I looked at the 550.. no way i would get that...Progressive is so much quicker...
I have a single stage press for my rifles.
I do not see how a progressive for rifles would work ...
What do you guys do with the lube inside the case necks ...
I check neck ID on my rifle rounds after sizing and clean off all lube..
I could not do that on a progressive any quicker than a single stage..
But pistol ammo ain't that picky..I do not shoot 45acp at the ranges of my 30-06 or 308.
Get a carbide sizing button for inside the neck and don't lube inside the neck. Dillon dies come that way.
Some resize and decap then tumble clean.
Then run through the progressive and start with priming only in the first spot.
