Seater die that pushes on the shoulder of a lead bullet

Apparently I flunked first grade in reloading, without knowing it.

I've just learned that seater dies are available for lead bullets such as the Magnus #801, that push on the shoulder of the bullet, not the nose.
Is this true?
How do I find one?
For 40 years I assumed you pressed bullets into the case, pushing on the nose of the bullet.....

Is this a die that accomplishes what I'm asking about?

Just buy the insert from eBay. Works in my rcbs dies

Insert????    I have no idea what you mean.

The insert that is in your current die that seats the bullet from the nose.

Search eBay for user rrpmi.

I use one of his inserts. He has them for RCBS, Lee, and Dillon dies.

I drilled out some of my inserts and added a little Dremmel work to get a shoulder seater.  For lead bullets, I use only the Dillon seater.

Hi, you're saying that they make something like the central shaft in the stock die, but it will contact the #801 bullet on the "shoulder", and not on the top?  
Sounds perfect, but I didn't know such a product existed....

Sorry about the sloppy image - first time I've tried "Markup" on an image.

I just looked at all the rrpmi stuff and he has some neat items. You can tell he likes to machine stuff for fun just to make a few bucks. Wish I had his metal lathe.

First off Mike I would buy the Dillon dies like I advised you the other day. Their seating and crimp dies are great. Then you can buy this custom shoulder seating insert as they're suggesting. I just use the stock Dillon inserts that seat from the nose but have good results. You can also buy extra Dillon seating dies off Ebay, sometimes I'll have 2-3 seating dies per caliber in LNL inserts so I can swap quickly between bullets instead of manually adjusting the die when you change bullets.

The Redding die whose picture you added to your post does NOT accomplish what you want.  But the video linked below shows how to modify the Redding seating stem with a Drimmel to do what you want.  But if you already own a Dillon seating die, then buying a modified seating stem/insert is probably the easiest way to go.

rrpmi seating insert is all you need. several models for different mfg. don’t need a high $$$ fancy die, just a cheap Lee is fine. get a recoil spring tester too!

The links to "rrpmi" don't seem to work.

I searched deeply and came to this site, but only for Dillon dies.

For 45 caliber SWC bullets I just use a 9MM full length sizing die in place of a seating die. The shoulder of the bullet contacts the bottom of the die and gives perfect seating every time.

I also use a 9mm size die for seating .45 SWC. Easy to clean and you can seat any weight of SWC without readjusting.

Hi, I already bought the recoil spring tester recommended by people in the forum.

I clicked on your link, then found this:
(It reminds me of what I'm thinking I'm looking for.)

I don't have any dies other than RCBS and Redding.   (....and a few old Lyman dies, but I think I gave them away.)

I have one of rrpmi's seating stems for my RCBS die in 45 and it works well.  A friend of mine uses Hornady's lock and load die in his Dillon and swears by it for the same reason.

I went with plan "C", as in Create my own.  I have a lathe I never use, and took the die part in the image I posted earlier, and machined it to make what I want:
(It was Dave Salyer's suggestion....)

1) A custom seating plug is often the best way to improve accuracy. One size fits all is a myth.
2) seating plugs should NOT contact the bullet's meplat/nose. A crooked bullet will only be forced more out of alignment due to "nose steering."
3) seating plug should contact the bullet's ogive/curved section as low down the bullet as possible.
4) seating plugs that ONLY contact the shoulder of a SWC will significantly self-correct bullet alignment

More things that I was oblivious to until now.  Thanks.  

You're making me wonder what everyone else doing reloading does.  Either none of that was in the reloading documents I read, or I didn't know enough to appreciate what they might have been telling me.

What would be a custom seater plug for JHP Nosler, Zero, XTP, or HAP ??

I started using Redding Competition die sets when reloading for rifle and continued with their Competition Seater die in pistol.  The seating stem fits way down on JHP and XTP style bullets refer to #3 in noylj's  earlier post.  For crimping I use a Carbide Lee Factory Crimp Die.

Dave, does the Redding Competition Seater Die accomplish the same thing as what I made?
I know it makes it easy to set and control the OAL, but does it also press the bullet into the case, without pressing on the bullet head?

I finished 24 rounds last night, will test today in my Caspian.  One round only had too much "bell" to fit into my seater die, which sounds impossible as the other 24 had no problem.  The only explanation I can think of is that this case was too long to begin with.  Maybe there's another answer I haven't been able to understand, yet...  Will probably just toss it out.  That, or buy another die holder, so I can work on things like this without disturbing my reloading setup for 45 ACP.
