We still have some rather big hogs in the Big Bend area of Florida that carry Spanish genes! The only hogs found on the hill are feral hogs. The big boys go well into the swamps and coastal islands. That is good as they take some specialized hunting. These big boars should be classed as dangerous game!
The guns we use are 12 gauge with rifled barrels, mainly semi-custom Remington 870 Express with Hastings barrels.
It should be understood that when you put a rifled barrel on a shotgun, you have an ultra bore rifle on a shotgun frame. The very basic knowledge you all have using hard cast bullets in handguns/rifles, still hold true loading the big 730"-730 grs cast bullets for the 12 bore rifles. Most of today's slug loads, Foster and sabot load are a compromise at best! First of all they are swaged lead and are too soft!
But, when you move up the heavy hard cast slugs, heat treated, you have re-introduced the basic Afican/India Paradox loads. Even the Lee Key Slug (one ounce only)cast hard and heat treated works good in both smoothbore and rifled guns. We have done a great deal of testing on the Lee Key Slug and found only one wad that would not strip when using hard cast......the Federal 12S3!!!!!! You do need about .200" hard card wad under the Lee, inside the wad, to set the crimp index. The 12S3 does not have ridges inside the petals and that is why it will not strip.
So......don't overlook loadind the big cast stuff!........Regards, James
