Hornady Lock-N-Load bushings

I have the Hornady LNL AP progressive press and it uses the bushings for the dies. I want to get a Hornady LNL single press that accepts the same bushings. Do you know if the die to shell holder distance is the same or will you have to readjust the die depth when switching dies between presses?
I think that made sense.

Probably not, at least within the specs that you might want or need.

I doubt that dies could be swapped between two L-N-L progressives without the desire to re-adjust the dies.

A seater die with a micrometer head can work well though if you record the setting for each press.

But I could be wrong, will not be the first time.:)

Don't know, but I'm interested in the answer. I also thought about getting a Hornady SS to complement my LNL AP, but if the die settings are going to be different, I might as well just stick with my Lee.

Check out this video on how to calibrate the LNL bushings between presses to eliminate the need to adjust when switching between the two:

Awesome, thanks.

That would be more interesting, if Hornady (or somebody) made and sold the spacers. How different can they be from press to press of the same make?

A custom machining order for one piece might have a stunning price tag. The video makes it look simple and fast, but I am guessing it isn't that quick and easy to make and would require taking a couple presses to the machine shop for measurements and fitting.

Lots of things are possible, but so far I just use an extra sizing die without the decapping pin in order to prepare cases from pulled cartridges to be recycled without loosing the primer. That setting is simply adjusting the die to meet the shellholder and then leaving it installed in its own LnL bushing. The press is a Lee cast that has the Hornady LnL adapter.

I suspect the variation between presses of a like model would have variation in the die holder height larger than what would be acceptable by most reloaders. Just a few thousandths of an inch is probably too great.

Depends on your definition of "stunning". If you go in with the dimensions that you need, there probably is a couple hours, or less, of machining time. If the shop does the measurements, it will get expensive.

I have found a lathe to be a useful addition to my shop. It falls into one of those categories where you cannot justify the tool before you have it but cannot live without afterwards.

Actually, I have one of those three-in-one tools that is a lathe, mill and drill press all in one. While I do a little precision work on it, and it is not the easiest thing to d. I do lots of quick and dirty jobs that would be a real pain to do otherwise.

When I first got a progressive a few years ago, I was concerned that it would be time consuming to swap the dies between the progressive and my single stage press. But, I have found that it really is not an issue and I do not have a need to swap the dies between presses.

Although, I do use one rifle seating dies on a progressive and a single stage press. It is a micrometer seating die and I just record the setting for each press.

From the video, using the single stage press to set up the powder measure for the progressive is a cool idea. But not cool enough for me to invest in another single stage press just for that.

But, I do plan to keep the space concept in mind should the need arise in the future.

I wonder if it would be practical to have a one-size-fits-all spacer of the minimum height, but which comes with a set of shims. We have that idea now in the shims Hornady offers to tighten the powder measure bushing. They are quite thin and are split for easier installation with a snug fit.

The above is a set of shims from Amazon.
I don't know if they would work with the LnL bushings though.
I would not think the bushings would be interchangeable from one press to another though. The thickness of the presses where the bushings go and the thickness of the shell holder/shellplate are probably different.

1 1/4 ID x 1 3/8 OD would raise all boats. You have to back the whole adapter away from the shellholder with press ram fully engaged.

The sleeve for the spacer, and from which shims would be cut, would be at least 1/8 thick. It can be much thicker up to about 1 5/8 OD to cover the entire machined surface on a press like my Lee cast single stage breechlock with LnL adapter. That would be max 3/8 thickness on the sleeve stock.

Something like this might work. (http://www.amazon.com/dp/B006U1S0L4/ref=biss_dp_t_asn)

You could figure out a way to make it work, but when talking about tiny differences between presses and shims, not to mention individual bushings I can only imagine the QC problems it would generate if hornady advertised that you could switch presses without adjustments

Can you make it work? Yes.

Will it be easy? Probably not

Will it be worth it? Your call

Would your solution work for everyone? Maybe

I will just buy a different sets of dies.

I'd like to be able to work up a load on a SS Rock Chucker say, and then just drop the dies into the L_N_L Progressive and load away. In my world, a difference of .005 in seating depth might open my group to an unacceptable size. Things that might cause that much of a difference could be things like:
--just a bit of "give" to your bench when you pull down on the handle
--difference in rim thickness in different brands of brass
--difference in thickness of the different brands of shell holders for the SS

Maybe I'm totally wrong about my speculations, but I haven't found a way to take all of the variables away.
