So now because I prefer the coax, I'm incompetent? lol Those that follow my content on youtube and instagram might disagree with you.I think most people who post good reviews for the coax are not measuring runout,
Co-Ax means same axis..., ONE axis....like co-ax cable....and all presses have to use the same axis for cartridge and die, meaning all are co-axSo now because I prefer the coax, I'm incompetent? lol Those that follow my content on youtube and instagram might disagree with you.
I have lower runout with my Co-Ax than any other press I've tested to date.
... and co-ax isn't a "marketing ploy." It's simply the truth. Co-Ax = 2 axis, and the die floats front to back, and the shell holders float left and right. Seems pretty straight forward to me.
The amount of misinformation in this thread is unreal.

?? Well, I can’t speak to the 650, but I’ve had a 550B setup for 22 years and it takes me less than 30 seconds to change calibers. Just get yourself a separate toolhead on a toolhead stand and setup your new dies on the head. Adjust them once and you’re set. One of the reasons I got a 550 instead of a 650 is that caliber conversions cost less money, about 2/3rds the cost, and I don’t want a case feeder. I handle and quickly inspect each piece of brass as it goes into the machine. It would be nice to have the 650/750 powder check die, but I setup a mirror that looks down into the case at station 2 of the 550. You need to buy the new caliber dies and a caliber conversion kit, then buy either the Deluxe quick change caliber kit that includes the powder measure, or at a minimum get a toolhead and powder die. I ended up with 4 toolheads setup on toolhead stands, with two powder measures. I have the Entirely Crimson quick change on the measures so I can swap them quickly (after draining the powder with a UniqueTek drain and change tool). I think the 650 change will be just as fast for you.
Ah! how we love are Rockchucker'sSinclair makes excellent stainless lock rings that work well with the coax also.
I've been using my coax for about 10 yrs now and it sits next to a Redding BB2. Ive compared the ammo produced by both using same dies and components and don't see a difference. One thing that might be interesting to try is to use centers similar to a lathe to see how rams and die holes line up. Granted, there is some play in shell holders and plates that allow movement.
I used a Rockchucker for 30 years which I passed on to my son when he wanted to start handloading and its as tight as the day I bought it. It still loads very accurate ammo.
