STI Saboted Hammerhead vs. Hog

[Apocalypse]

Dominion Arms in Canada offers (offered?) zinc 12 gauge 2 3/4" slugs. I don't know the loading, though have shot a few. Seemed to work just fine in my various smooth bore shotguns but not very good in a rifled 870.

"Zlugs" worked great in full bore from rifled gun, "Zamak3" which is 96% zinc and 4% aluminum cast in iron mold. Gotta know your groove size exactly cause that stuff ain't swaging to any barrel. Mine punch nice .731 holes in most anything launched near 1700 fps mv out of heavy ultra slug hunter. Mold that cast 775 gr in lead were 477 gr in the zinc alloy.

If I came across a 20ga fully rifled barrel I'd use full bore Zlugs

Jason, I'm going to test my theory on the 16mm vs. 25mm brass with the Marlin 512. I placed a Grafs order, thank you for the link.

Jason, the 25mm base shells were made for the 512!





I also modified my load just a bit by using a ⅛" 20 Ga cork wad inside the sabot pressure's wad powder cup. I felt that the fold could be a bit "tighter," meaning that I needed a bit more stack in the hull. You have to have something hold the cork in place as the wad is pushed into the hull and it is hard to find something that sticks to either, just long enough to get it seated. A glue stick worked, and I have a very tight six-star crimp made with the Lee Load-All II. The clear hull on the left was my previous work, the star is just a little bit uneven.

Michael: Have you tried just loading the 3" hulls normally and using a Long Roll Crimp to close the hull?

Yep, I have several roll crimpers. Hands down a six-crimp star deliver better MOA performance at 100-yards in both the Marlin and Mossberg 500. I have absolutely no plans to return to the roll crimp.

I have a 3" die coming for the MEC Jr.

Greetings, I too had found it out early on the fold crimp gives better combustion and the accuracy was far better with fold crimp. Most of my loading and testing was with fold crimp.

I use to have two drill press with roll crimp just sitting there, still do.
