Anyone have a trick for loading the Co-Ax bench priming tool?

The Co-Ax bench priming tool works great. However the method of loading the tubes is very tedious. Any tricks or mods out there to get the tube (magazine) loaded?011521-primer-seater.jpg
 
actually i have one i used to use a lot. has a good feel on primer seating. A little tricky setting up the shellholder

that notch at the end of the base fits the primer tube perfectly. i take a mini straight screwdriver and just rake them into the tube. the tedious part is flipping all the primers anvil up. i found by taking the screwdriver and pushing them into the rounded corners they flip easily. with a little practice you can do it pretty quickly.

now i use a sinclair that requires me to handle each primer individually.
 
When I used the above tool, I loaded the tubes in an RCBS primer tray with the tube clamped to the tray.

To adjust the jaws, I cut a bushing on the lathe for each cartridge case head size; belted magnum, 308, 223, etc.

And your priming tool is which one?
I have a ram prime that works well for odd ball cases. I also have a K&M that works ok. I have the little RCBS bench top tool that is a single primer tool. I also have a Dillon press with primer feed. But best of all are the 6 or 7 old original Lee priming tools with the screw in shell holders from the late 1960s. I paid about $2 for the first one. They always work except when I do not have a shell holder for the Lee tool. Then I use the little RCBS bench top tool or the ram prime because they use conventional shell holders. The only rounds that I prime in the ram are the .405 Win and the 50-70 Govt.

The Coax priming tool is a classic example of attempting to make the design so different that it would stand out in the market place. Marketeers call that "product differentiation". The marketing angle was pursued to the detriment of the function. This is just another case of being so smart that you make a bad idea work.

I have a 21st century hand primer that I use for target loads. For plinking AR15 loads I am using the Co-Ax as it provides a little less effort than the 21st. I also have a Dillon and a co-ax press.
 
I recently obtained the Loading tray for the Forster Bench primer and finds that it greatly simplifies the loading of the primer tubes. What I particularly like about the Forster Bench Priming Tool is that it is small enough that it sits on my reloading desk without taking up much room and no need to mount to the desk or a board for that matter if preferred. I also find the shell holding jaws very easy to adjust for the various calibers I reload. Not being mounted, I simply stand the priming tool up on end, press the lever and adjust the jaws to the shell casing leaving them loose enough to allow me to freely turn the case in the jaws which allows for tolerances of the various cases. I can effectively prime the cartridge cases with no problem. The feel of the primer be seating is very precise and easy to seat. I have had many priming tools in my day and find this to be one of the most convenient and accurate priming tools especially now that I obtained the primer tub loading tray from Forster.
 
for the 21st Century hand tool...have two, one for large primers..the other for srp. I'm old and lazy.
 
Adjusting the jaws is dead simple- use an unprimed case, push the lever down so the case can register centered on the ram, adjust jaws. Bottom jaw fairly tight, side jaws give a little side clearance. One side of the jaw is for thicker rims, one side for thinner, use the correct one.

Round corners of tray are for flipping so anvil is up.

When all else fails RTFM.
