Buckbuster 12 gauge slug

[Ranch Dog]

Is there a link to the full-bore Buckbuster?

My Lee 7/8 were about .688 to .690 with range scrap lead

Is there a link to the full-bore Buckbuster?

It has never existed. The "link" is the 45.2.1 design in this thread
It is a TL design that should coat well with PC or HiTek or even TL

[megasupermagnum]

I have the Lee drawings, the design is .681".

I have NEVER seen a Lee slug cast that small. Mine cast .687". The smallest I've ever seen posted was .685" and many are up to .690".

[jmort]

I will just pray the 45.2.1 makes the call or gets the nod
I would regret, but live with a lesser design
Do not understand ignoring the greater

Which is why they are worthless

Hmmmm... I'll have to check my Lee slugs later. Pretty sure the 1 oz. casts about 0.685" and the 7/8 oz. 0.683". I'll check again.

[longbow]

Okay then, just checked.

My Lee 1 oz. slugs run 0.685"/0.686" at the nose and a little larger at the seam, and 0.670" pretty consistent at the skirt.

My Lee 7/8 oz. slugs run 0.680"/0.686" at the nose (I'd say mould blocks are slightly out) and 0.660"/0.667" at the skirt. Definitely oval but again likely mould blocks are out of line. This one should be lapped.

These are all cast in ACWW. Other alloys might cast larger.

Both cast well and slugs drop out. I haven't really used either enough to draw too many conclusions except that slugs from my home made moulds group better with components tested so far.

The 7/8 oz. are sloppy in my Winchester wads for my 0.733" bore smoothbore so one wrap of paper snugs them up. Lapping may fix that. But then my Mossberg Slugster has 0.729"/0.730" bore so they may be okay there. With bore size slugs, being a bit oversize is a bonus I think but with wad slugs too tight a fit seems to result in sheared petals.

My measurements were at the widest part of the slug.

I came to the same conclusion. Out of every wad I could find, only one combo was acceptable in my largest bore smooth bore shotgun.

.681" perfect fit in the bottom of a wad, but a little loose at the top, as every wad tapers slightly. This is ok, and if anything it helps keep wads intact through the forcing cone and into the bore. Once in the bore, the idea is that they obturate to a perfect fit. That is the beauty of the buckbuster slug. I still have all the instructions and load data, and they even recommend working up loads past their listed data until wads begin to shear off. They knew that the harder you push them, the better they fit... until the plastic wad gave out. I have recovered slugs that even show lines in them from the slits in the wad petals, that's how well they bumped up.

Would you share that load data? A guy just can't have too much slug load data! I'm always looking to add to my library!

I've posted this before. I can take better pictures if it's too hard to read.



Take a close look. You can even see the lines from the wad petal. This was recovered from the 200 yard range.






I just read them myself. I knew I got the 20 gauge AA wad trick from somewhere! For many years to seat slugs I've used a 20 gauge AA wad with cup cut off to protect the slug nose from the MEC drop tube. I even leave the crush section, and it slides right inside the drop tube, it does not fall out.

[longbow]

I did a search but didn't turn up your previous posting of this data. The pics are a bit hard to read but I downloaded them all anyway. Thanks.

Those slugs must be pure or near pure lead to deform between plastic petals! The setback and filling the bore is obviously the goal and reason these worked. I'm thinking a somewhat oversize full bore slug should accomplish the same thing by squeezing down.

Still on board for the original Buckbuster at this point,

I’d be in for at least 1 mold

Ok, I took the Buckbuster documents to a scanner. Hopefully these show up better.

Indeed they do! Thank you msm!

I found my old articles on the Buckbuster "shotgun bullet" by Mike Bleech. Only one load given but lots of praise about accuracy and easy loading and the repeated how to work up until petals shear then back off a bit for best accuracy.

If anyone is interested I can scan and post those articles though they are not "technical" nor full of load data. Still, an interesting read.

With any luck we'll be repeating Mike Bleech's successes!

Let's get this group buy going!

For what it's worth, I found the load data to be great. I'm pretty sure I used the 7th load down. I know I used a Remington hull, Claybuster wad, and 800X powder. I don't think I was able to increase powder without petals shearing. That load shot about 12" at 200 yards if I remember correctly, better than many factory loads. 100 yard accuracy wasn't as good as many factory sabot slugs, but was in the 3-4" range. I believe my only rifled shotgun was the ultra slug hunter at the time. I did try them from smooth bores, but don't remember how they shot.

Any update on this?

[bluejay75]

Final design on the way. One more time for alibis then off to Miha.

Is it too late?
