Seen and added my 2 cents.

Bullet Swaging Supplies (BSS - Larry Blackmon http://bulletswagingsupply.com/) makes a small swaging press that will take M-type dies (3/4" body & 5/8"-24 tpi threaded tenon) and is significantly...

If you're looking to demand a fair price, I'd suggest getting the original, or one of the known bullet swaging die makers, to assess the condition of the die set and press; and the quality of the...

Most point form dies are open-hole designs given the use of an ejection pin. The exception would be something like the RCBS type point form die design which splits at the ogive/shank junction.

Forward extrusion, not reverse extrusion?

Do you pre-heat the die and/or lead billet to get the extrusion started, or just go from a cold static start?

Do you operate the coil winder manually,...

Spin stabilized projectiles are more like javelins than arrows.

Fin stabilized projectiles (e.g. rockets) are more like arrows. Sometimes the fins are canted to induce a small amount of rotation,...

You see older models available on that internet...

So here is a picture(courtesy of my swaging mentor) of Larry's carbide die attempts.

Flat base core seater and point form carbide dies sets in 224, 243 & 308. The 224 & 243 cal point...

I saw an interesting carbide die the other month produced by Larry Blackmon at some stage during his career. Basically a full diameter body M-type carbide die, but with a steel threaded sleeve...

Try Bohler-Uddeholm for a some comparison of wear rates. I'm not sure about 4140, but they have some comparisons for tool steels and HSS in the product data sheets.

My preference is for H13 as it...

The more you learn (including the questions you ask), the more you realize that there are too many parameters you can't control enough that affect the end result if you don't make punch & die...

Nice work!

I assume there was a lot of good learning there in replicating a commercial system that works?

This should definitely give you confidence to machine your own punch & die designs.

You could always dummy up a punch with a piece of dowel to get the optimum length to match the press force and displacement curves.

If you are still considering a bullet reducing die, how are you...

The bullet swaging die makers usually talk about a 0.006" reduction as maximum in bullet diameter. I can't help but feel this number reduces as you go smaller in caliber.

I currently have 2 bullet...

I'll give another tick for Dienamics in Brisbane. :-)

I knocked on that door a few years ago doing a bit of due diligence before getting into swaging myself and pretty much got the same response.

From what I understand Malcolm has done everything on...

BAM - Bullet Assembly Machine

www.greasymachines.com also has a good range of the different brands - Platarg, Baird.

There are other French, German, Spanish and Italian manufacturers as well if...

I agree..."least amount of pressure"

Does your core seated jacket measure the same OD (+/-0.00010") across the base compared to the punch lead line?

A repeatable core seated jacket diameter...

Diameters are okay, just the actual cutting edge/corner itself. Typically I'll spec out a 1mm or 0.2mm radius fillet on edges so the machinist isn't left wondering.

At the moment I've spec'd out a...

Anybody familiar with the CAD drawing tolerances (or symbol) for describing a cutting edge on punch and die tooling?

Just finishing off the dimensioning a pinch trim die, any assistance would be...

For those that might be missing the manual to their machine; and those that are interested in the operating principal behind the unit, here is a link to the US Letter and ISO A4 version of the...

Yep, it won't be long before we're taking a section of 380 PFC (or the imperial equivalent) down to the auto cylinder workshop to see if they can bore a straight hole; and welding together a few well...

When target rifle (TR/fullbore) in Australia was restricted to the 144gr FMJ 7.62NATO projectile made by ADI for machine gun ammuntion, bullet reducing evolved along with tighter bores. Effectively...

I would have gladly paid for the annual $2,500 ITAR licensing fee myself if Richard was prepared to export high quality 95/5 jackets for long range target shooting.

As it stands I can't even get...

Just following up on my previous post.

The shoulder bolt is 3/8" diam x 1 3/4" long with 2 x 5/16"-18 tpi (UNC) lock(half) nuts to suit the short thread.
