No casting for me ... use what i can buy and modify them if wanting more expansion. If not shoot them as is. No Big Bore here either.

If you use such a solid "cutter" the bullet will deform, you need something as thin as possible, check on corbin press, the x punch and the saber tooth punch.... same principle as a the phillips screwdriver but much thinner. I tried the tap holder but the blades move, need to brazed them I´ll add some photos later

This are the cutters I tried:
A solid one meda of a piece of steel and a tap holder with hacksaw blades grinded to size.... both work, the tap holder is a little better but needs brazing
I use a corbin style swaging press so after the cutter I use the original slug die and form is recovered. Solid cutters like your broadheads will distort the slug to much

Thin blade (left) vs sharpened phillips screwdriver bit and a slit slug after reforming (right).

What is required for the reforming? (I don't make my own slugs)

kimoleto · « **Reply #66 on:** April 06, 2021, 12:47:09 AM »

I use a swaging press, a reloading press can also be used. I swage the slugs, cut the slits and reform them...time consuming but satisfying

I would take a metal stem that was as deep as the original bullet/slug,
give the bullet/slug several good coats of paste wax/mold release agent,
fill the metal stem with Epoxy, insert bullet/slug square and true to depth,
let epoxy harden, then use this mold to reform the slit bullets/slugs back to OEM shape.

This can be used in my pellet forming press, along with the slitting punch..........

That might work, you dont need a lot of pressure to reshape the slug, its worth the try. I made the dies from aluminum, my lathe is small and not a lot of skills from my side but they work.
Drill a small diameter hole through your "mold" then drill a larger one and use the epoxy, do not fill the small diameter hole and use it with a small dimater rod) to extract your reshaped slugs. Good luck and share your results

Thats how you make a slug on a corbin press, obviously not my video just found it in youtube

kimoleto · « **Reply #70 on:** April 08, 2021, 07:47:29 PM »

What if I cast the slug with a cutter inside the mold? that would possible give me less distortion, some time ago I made some molds for HP slugs and last night got the idea... what if I modify the HP inserts? It might work

Insanity · « **Reply #71 on:** April 08, 2021, 08:10:50 PM »

Stick a sharpened Philips head or torxs bit in and find out.

kimoleto · « **Reply #72 on:** April 08, 2021, 08:33:24 PM »

They might work, but are to big, you need to make the "wings" thinner

kimoleto · « **Reply #73 on:** April 12, 2021, 08:36:58 PM »

I followed your advice on using steel from a razor blade (0.0106") vs a hacksaw blade (0.0226"), then I use the cutter inside a cylindrical die (the slug is inside the die, there is a punch moving from bottom to top and the cutter moves from top to bottom)...results are perfect, now i can slice the slugs within 1 mm of its base. The blade cutter holder is a tap wrench, just moded so it can be placed instead of the upper punch of the press . Slug is cut with almost no distortion.

Wow, nice work on your slug slicer! Can you please post more pics of the blades and details of the rest of your tool? I can clearly see I have been slacking and need to get in the game on this project as I need some 'make'em pop' slugs.

I´ve been using a swaging press (not really enjoyed casting), it was a DIY project from another forum...dont know if I´m allowed to post the link. Is not easy to make but not impossible either. I have no prior experience with lathe or mill work but managed to finally finish the press. Then the dies (cherry cutter is a new word for me!!!). The X cutter is simply a taping wrench since its already divided in 4, so 3 pieces of thin steel (a single edge blade was the source of steel), carefully grinded until correct size was obtained. My goal is .30 sliced slugs (almost there), but also own a .40 and a 25 modified AF condors (waiting for this kind of slugs). I´ll post more photos, sorry about my english and lack of technical expertise. Hope this helps

Ruben, I normally would have just PM'd you, but I think most of the people here would appreciate seeing your progress and ideas. Not everyone on this forum has advanced machinery, so your solutions can be duplicated by almost everyone with enough patients and hand skills.

As for what you can and can't post, the rules are pretty clear on the 'rules page' however that is also why there are moderators. You can either send them a PM with an inquiry as to if your idea is ok to post, or post it and they will remove it if it is not ok (first method preferred).

No oligopolies necessary for your English, your point comes across perfectly well, also "a photograph is worth a thousand words", your use of images with your description has been valuable in your explanations (some people are just more visually orientated).

Sadly my own work with my slug ideas has stalled, just too much going on with the family and my 'real job' to get any 'hobby time' in right now.

Keep up the great work and by all means please continue to share (this applies to everyone

Who doesn't like innovation?

OK I checked the posting rules and I´m allowed to post and external link, this is the link to the swaging press DIY project: https://castboolits.gunloads.com/showthread.php?76514-Lets-make-a-Swage-press

Its not easy to make but with some patience you can make one, the plans are very detailed and the the press works perfectly, I could not get the suggested steel mentioned, instead I got common iron (?) from a scrap yard and so far it works OK total cost of material was less than 50 USD (I´m in Mexico so price will be different in the US).

The press needs dies thats the difficult part, the inside is hollowed with the exact slug form. You have to make the slug form in O1 steel (you tube has excelent videos) and then make the die. The press has 2 punches, one on the top and one on the bottom, the generated pressure makes the slug and you control particularities (HP, BT, etc) using different punches. Check this video
Due to my lack of skills choose aluminum instead of steel for die making, so far they are OK, no big issues with them being softer than steel.
Another excelent video

As an option You can buy a Corbin press and dies in the US, problem is that they are really expensive, even a reloading press works too, you can find some info in Cast Boolits forum.

I´ll add more photos later

More photos

The new X cutter

kimoleto · « **Reply #79 on:** April 13, 2021, 08:12:59 PM »

First and second photos are core forming molds (they form a small lead cylinder) third photo is a Slug forming die with lower punches inserted (slug is formed pointing downward)
