Coaxial vs rock chucker

[Colorado Cowboy]

I use an RCBS Turret with all the dies and powder measure mounted on the turret. I just change turrets and powder measure when I change calibers.

Me too. I’ve never understood how swapping dies seemed to jam people up so bad.

Yeah, i dont get it either. How is repeatability any different for a lock ring in a coax vs a lock ring screwed tight to the top of a traditional press? What am I missing?

I didn't think they made a case ejector/kicker for a coax which is a deal breaker for me but saw this vid. Not sure if this is a product that's currently available?

That’s pretty cool - a case kicker speeds up 223, 300 BLK, etc. would be a pain to have to take the case out each time.

I like the look of the SAC Nexus, but not sure if I’d be willing to drop the $$$. My Hornady isn’t perfect, but still gets the job done.

I switched from a Rockchucker that I learned to reload on 30 years ago to a Coax a couple years ago. Not sure why, just a wild hair I guess.
I do like it's features quite a bit more and the "self aligning" nature made sense to me.
Not sure if it was totally worth it, but I do like it.

Only press I've ever mounted to my bench is a basic Lee Classic Cast. Of all the things to blow $ on, a gucci single stage feels like the least bang for your buck especially if there isn't commercially available shell ejectors/kickers. Finally got a Dillon 550 last week but have yet to set it up.. I dont think I'll use it for sizing much because its probably still slower than my Lee unless i wanted to expand with a mandrel or deprime in a separate stage.

Once you set the Dillon up I’ll bet that Lee just gathers dust
Put a drop of oil under the primer transfer bar and run a bit of powdered graphite through the powder measure to slick things up before you use it

I kind of doubt it. One sizing die with a shell kicker is quick and easy for size/deprime on the Lee and the Dillon can stay setup to prime, charge, seat.

I have both the Forster co-ax and a rock chucker, I perfer the co-ax but both have their place on my Bench, if I had to get one I’d get the co-ax with the SAC lock rings

I have both also, both do a good job. Find myself using the coax more than the rockchuker.

Get back to me in a years time, I would be happy to lay a few bucks on the result

I bought my RC2 in 1994 and loved it. I loaded a LOT of ammo on it. I bought a coax a few years ago and haven't touced the rcbs since.

Take the handle off the coax because you won't need it. I had swapped my RC2 to hornady quick change bushings and added a spacer to swap back and forth with my hornady press and not reset dies.....now, they're all sitting there lonely and the coax does the work.

The coax has the slowest priming of any press ever, BUT, it also can be as accurate on primer depth as the most expensive. I just bulk prime with a hand held and if I want to play the crush game.....I can.

The coax is faster, easier and more accurate.

The die floats in a forster, i polish the lock ring to assist even further in doing so. Spoze it’s whatever you have confidence in and get the results wanted, we all have our methods and beliefs in such to get there…Forster is a great company. Good luck.

If you look at Cal Zant's Precision Rifle Blog, the Rockchucker is the most popular press in the PRS amongst the Top 200. The Co-Ax is the 2nd most popular.

Can't really go wrong with either, and neither will hold you back.

But priming on the Co-Ax sucks. If you don't want to get extra tools, then the Rockchucker would be better from that standpoint.

Old thread, but I'll add that I, too, never understood how changing dies constitutes such a major hassle. I should also add that I don't adjust dies much other than to have them in far enough to get full contact with the deck of the shell holder.

Changes in the amount of case engagemt into the die are made with Redding competition shell holders or shell holders that I've ground down if more engagement is needed insteaded of less. Getting full contact with the die base has yeilded very consistent ammo for me over the years, both in terms of concentricity and overall dimensions.

I'm still using an old Lee press that I bought second hand 20+ years ago. By always going shell holder tight to die base, Im pretty well taking any play or inconsistencies in the press out of the system. Of course, I have more money tied up in a bunch of sets of Redding shell holders than the cost of a good coaxial press, but is what it is; I'm happy with the end results.
