21 century vs pumpkin Why?

I’ve never used a Pumpkin.

I do have experience with 21st Century and PMA. Both work, but IMO the PMA equipment is a step above. I find the depth of cut adjustment to be more precise and easier to adjust. I also feel that the brass fit on the turning mandrel after it comes out of the sizing mandrel is better on my PMA equipment. I found the 21st to be a bit on the loose side for my tastes. As always, YMMV.

just read through this as I was doing some comparison today and 21st is very loose

The 21st expander mandrel is sized .001” larger than the turning arbor resulting in a fit around .0005” after springback. If you are having issues with a loose fit please let me know. You could always try an incremental expander we offer for a tighter fit if needed. If a loose fit is an issue feel free to contact me at pete@21stcenturyshooting to discuss. Thanks!

Very happy customer here. Like anything, a person can get a bad one, but you are great on customer service. I have all 21st Century products and love them!

Unfortunately I find the design of the instrument lacking. The Mandrel has too much precession as its never fully locked... its cutting on the way in and out as it oscillates. I have had the 21st century for sometime now, I was never into neck turning I started recently again and feel that the PMA and the Pumpkin are sturdier. I have not touched the K&M in a while, but from what I remember it did not have any oscillation. I did expand with the 21st century mandrel and the turning mandrel is also the 21st century carbide mandrel. I am not a fan of how the lathe has that articulating joint, I feel much more confident when the brass is locked into the shellholder without articulation.

Nielsen Pumpkin is great, simple and repeatable. With our without lathe, it will get you to tenths accuracy.
 
I have to say, when the 21 is used with proper technique. I get perfect results of 2 ten and a lot of time actually I have gotten 1 ten. You really cant get better. They are all nice quite honestly pma is sweet to, but I prefer the lathe up and hooked up my own motor. Even tho 21 lathe floats, which is on purpose, with the lathe attachment and a motor, things stay very straight while operating. The pumpkin is sweet to, I just hate not getting to see progress of what is going on.

Not getting to see progress? I can see it fine but yes its recessed. I don't think its necessarily the best neck cutter out there most of them can produce results if used properly. There are, however, a number of opinions on 21st century mandrels. Its not the device necessarily but also the mandrel tolerances. I am just stating what i have found.

If you wanted , pma carbide mandrels will fit 21st if you like the lathe setup of the 21

A valid point. I should give that a go and see what happens. If same thing then its the tool itself clearly.... I have a spare sinclair mandrel I can use also I am kinda not wanting to disassemble the PMA...
