Priming on a Co-Ax

How many people use the priming feature?

I have used ut just a bit and find it's easy to mess up case rims if you run the handle too far up.

Any thoughts?
 
Re: Priming on a Co-Ax

I never use the primer feature on my coax, you can get way too much leverage and it's slow, go get a decent hand primer (i use rcbs universal) and squeeze away much more feel you'll know if your primer pockets need to be worked on

I did fashion a make shift stop for the ram and it's better, but I am not feeling warm and fuzzy about it.

Seems finicky to get adjusted as well.

Same here. I've never had a problem with mine.
 
Re: Priming on a Co-Ax

I have primed many thousands of rds with my 2 co-ax presses . I have ruined probably 15 cases by bending the rims . To avoid this make sure the 3 'fingers' are properly engaging the rim of the brass and don't exert more force than is needed to seat the primer . Once you get it properly set up and realize you don't need to 'bust a gut' to seat the primer you will probably really like priming on these presses . I have used ram prime , rcbs press to prime, rcbs and Sinclair hand primers . I greatly prefer the co-ax to prime with .

Cool. Special thanks to it fw707 for the PM's and vid.

All in all I do like it and think if I can tweak the adjustment just right it will be good. The supplied tool / insert seems to allow a lot of case movement this my uneasiness getting it adjusted. It does take a bit more feal but seems quite consistent with depth.

Exactly.
I put my hand right where the "yoke" section meets the handle. That decreases the leverage and improves my feel for when the primer bottoms out in the pocket.
 
Re: Priming on a Co-Ax

I use the Bonanza - Forster horizontal shaft repeater, not the single shots, with vertical shaft, built into my co-ax presses.
They all use the same three piece jaws.

I load the tubes with a milled out RCBS tray.

Just one; don't run the handle too far up!

Re: Priming on a Co-Ax

I use a Lee handheld. Its good being able to feel the primer as it seats. Plus you can tell easily when to primer pocket is toast. Its also fast in orienting the primers with the rings in the bottom of the tray.
 
Re: Priming on a Co-Ax

i keep the co-ax set up to prime some low-volume stuff (480 Ruger) and never had a problem with it.

for match ammo, i use the same primer pictured in clark's post. works great.

i will say i have twice set off a primer in it over tens of thousands of rounds and maybe 15 years. I learned after the first time to keep my pinkie up like a wine sniffer on the coasts instead of letting it dangle in front of the case mouth

Re: Priming on a Co-Ax

I use the primer setup atop my Co-Ax for the odd-ball cartridge in my stable... .338LM. Nearly everything else is regular .378 or .473 case head size, and I have various other setups to speed those along.

Read the literature on the press and you'll see this is an inaccurate statement.
 
Re: Priming on a Co-Ax

I use mine more and more and I like it. Also have a Sinclair hand priming tool and the Lee priming tool but I like the convenience of the Co-Ax. It does the job good enough for me.
 
Re: Priming on a Co-Ax

I've never done priming any other way than on my CO-AX. I've only torn through the rim one time in 4 years, and the fingers for case position were not set up correctly. I like it alot. I thought about getting a hand primer just so I wasn't tied to my bench while priming, but then I thought maybe watching TV while doing reloading tasks may not be a good idea.
