Upgrading from Rockchucker to Co-Ax
#1
It's been 6 years since the post discussing T7 vs Co-Ax-- so I hope I'm beyond the statute of limitations for redundant posts. I believe I understand the differences between these two presses, and I'm concluding that a Co-Ax makes sense for me. Looking foward to simplyfing my workflow. Also, doesn't hurt that I'd be in good company.

Would experienced folks venture to suggest what I might use my Rockchucker for if I keep it- bullet puller? Other? I have a lot of bench space.....

I shoot and reload 6.5 x 55 Swede, 204 Ruger, and 6.5 Grendel. My wife shoots 357 and I may get a lever action in same caliber, so some potential for reloading there as well.

Thanks

I’ve got multiple single stage presses. T7, Co-Ax, MEC Marksman, Lyman All American, Rockchucker. I have the Rockchucker dedicated to removing the military crimps in 5.56 brass.

I have both presses, and while I don’t shoot any 204, I believe its the same rim size as 223/5.56. That means you’ll have to swap out the “jaws” (shell holder) of the Co-AX when resizing the 204! Not the end of the world but, it can get to be a pita if you go back and forth between calibers often. If it were me, I would consider setting up the rockchucker for depriming/resizing 204 cases. Then you can probably get away with just seating bullets in the Co-Ax and the 204 without having to swap jaws.

MPS:

I recall those posts and I believe they were in response to guys asking which was better for them so they could make a decision on what one to buy. The Co Ax came out ahead for most guys.

Not a lot wrong with the Rock Chucker providing RCBS made it so the ram is in good alignment.

In terms of speed of reloading, both are about as fast. The Co Ax is easier to change dies but a huge PITA to flip over the shell holder as Harpoon 1 said.

Best bet is to use the Co Ax when you demand as little cartridge run out as possible and the Rock Chucker for things as it is convenient.

If you are going into lever guns and pistols / revolvers and intend on shooting more than about fifty rounds a week, you may want to look into a turret or a progressive. Gets really tedious loading pistol ammo on a single stage.

i use my Turret press for handgun cartridges, best thing for the Coax I have added is https://www.forsterproducts.com/product/...-ax-press/ but I do load from very small 22 Hornet to belted magnums on it. That does make changing out for different sizes easier.

The quick-change is cheaper on Amazon

I’m sure the “new” self contained “jaws” do help speed things up some and make it less tedious. I’m still working with old design and “un-captured” springs! Cool And I’m with you on the turret presses. My Lyman All American is a dedicated pistol press!

H1:

Me too. Always get nervous when I have to flop the jaws over. Tiny springs, large and cluttered reloading area. Not a good combination. The priming system on a Co Ax must have been an afterthought and done just to check a box. Total PITA.
