Hoening Big Bore South: A Fully Rifled .410 Slug Barrel

Now this is a .410 slug!
Now this is a .410 slug!

Honestly, I could not believe what I was reading. Hoening Big Bore South (HBBS), in collaboration with Hornady, Montana Bullet works, Forster and Lee loading (to name a few) have developed one heck of a .410 slug.

When I first contacted Jim Hoening he sent me a great e-mail  response thanking me for my interest and granting permission for this article. His knowledge of the .410 bore, coupled with a great personality, are going to push this company a long ways. Check this out for a .410 deer slug! .370 grains! thats a BEAR load for sure. We are talking 45-70 range now!

But wait – I am only talking about the slug – HBBS slugs are worthless without…a FULLY RIFLED BARREL for the .410 shotgun line. These Barrels are built for the Thompson contender/G2, and  Encore rifles from Thompson Center Arms. These barrels have a medium/heavy taper of .810″ and are 24″ in length with a 1/14 twist. Each barrel is delivered to you drilled and tapped for both a scope  and fore-end attachment. These barrels are 10 years in the making and if you are looking for .410 slug gun that is fully rifled check out the shot group below left.

Slug groupNot too shabby is it?! I didn’t think so myself. Having worked up some of my own specialty slugs for my .410 I was duly impressed with the HBBS rifled barrels.

HBBS has done something that I only dreamed of in producing this barrel configuration. Let’s face it, driving an uncrimped .375 grain slug from a cylinder bore should NOT produce adverse pressures – and it doesn’t. Hoening has the scientific data now available for these loads as evidenced by the following quote from their ballistics page:

“Prototype loads for the HBBS 410 Heavy factory load and the HBBS 410 Youth load have been laboratory tested and have been found to be within SAAMI specs for 410 bore chamber pressure. It is now a scientifically proven fact, believe it or not! These same tests show very consistent velocities from round to round, another contributing factor to the extreme accuracy.”

Great job Jim and staff – this has been a long time coming!

    HBBS is Very interesting. Is this development alive with barrels, bullets, molds? Or dead?

    So I’m guessing this is a no go for the Taurus judge?
