Rock chucker deprime mess

[Bob Willman]

I made this alteration back in 2005. It is a 1/4 inch piece of wood inserted behind the primer catcher cut as shown in the photos. First photo is the spacer removed and the second it is in place holding the catcher against the ram. The primers cannot escape. Cost = CHEAP.

I've never had much trouble loosing primers. I never counted but I'll guess 1 out of 100, maybe go flying. It seems that my universal die works better than a loading die that deprimes and bells the case mouth in one step. Its like it builds up pressure and the primer goes flying! I also put a piece of cardboard in front of the plastic tray.

The "obsessively clean minded" among us have always had this issue with the Rock Chucker and presses of similar design. These are really "first generation" designs. They've not really progressed in the area of spent primer handling since ~1970.

I suggest you look at "second generation" presses which route 100% of all spent primers through the center of the ram. From there the spent primer, and more importantly the accompanying primer smut, can be routed to a sealed container under the bench. Not having the primer smut get lodged around your ram, and not having health issues develop from breathing the lead-laden dust are really a big issue.

Check out the Redding Big Boss II and T7 presses, also the MEC Marksman. There may also be several others. When you compare this to the add-on gadgets for the Rock Chucker I thing you'll realize that those accessories are little more than band-aids and not real solutions.

Hope this helps.

I found the aftermarket attachment for 30$

While I'm completely happy with my RC II, I'm not going to disagree with your advice. When I had a Lee it was nice to have the primers drop down a tube. But, the trick right now for somebody looking, is finding a Big Boss II.

any DIY solutions?

Most (but not all) of the primers that don't make it into the pan on my Rock Chucker Supreme land in the plastic, 5-gallon bucket sitting on the floor under the press. Every once in a while, either my wife or I sweep up the ones that didn't land in the bucket - it's an unfinished (concrete) basement floor anyway.

I gotta ask what is the straw trick/

 

[ciwsguy]

Just out of shear morbid curiosity, do you throw away your spent primers or save them for possible primer reloading? Primers on retail store shelves are unobtanium in my area. Those to be found on line in GB are legalized rape type pricing.

I’ve started to save spent primers just in case.
Yes, they are messy and that stuff sometimes gunks up my hornady press. Some end up on the floor with that brand too.

I have a RC IV...and yes, I do a majority of my depriming on it and yes, the thing is a mess. No matter how hard I try, I still get the ones that fly out the front and hit you in the gut, or just "pop!" out and shoot to nowhere. It's irritating.

My solution with the Rock Chucker is a shop vac and vacuum the floor .

I’ve done the same with a piece of balsa wood and works 100%.

I gotta ask what is the straw trick/

Take a McDonalds drinking straw, or any other that is larger than normal, cut it to fit into the groove in the ram under the shell holder, it will stay in by friction. The primers stay in the straw until they pop out the straw at the very bottom. Thus they bounce less and stay put.
The cardboard, or NRA card, will stop any others that try to misbehave.

I got a small piece of foam between the catch pan and the press to move it forward. Now it catches about 95%.

I've only seen it used on pre -IV models.....
I added to the straw and now have 100% primer catching.....and a case kicker too....

See the red McDonalds straw peeking out of the ram slot? I drilled a hole in the bottom of the primer catcher, drilled out a .357 case, and epoxied the case in the bottom of the primer catcher....a clear tube slips over the case to a bucket.

Here is my bench set up.I just got the press on the left the other day so my grandson can help me de-prime, so I guess I gotta buy another one of those gadgets so both presses can operate if needed.
