Been experimenting with a buck and ball load for a safe to shoot, 10 gauge antique shotgun.

Best results so far & test fired at 18 yards:

-Parker Brothers 10 gauge all brass shot shell, using large pistol primer for ignition (one can use a 2 5/8 or a 2 7/8 inch brass shell)
-one over shot card over top everything and sealed in place with clear silicone
-one .58 round ball
-nestled upon, (and sitting on the very top of) three .375 buck shot pellets
-glued together with gorilla glue, and yes all shot and this done outside the case in a totally separate earlier procedure
-one over shot card
-cut in half 9 gauge Circle Fly cushion wad
-two 9 gauge diameter Circle Fly nitro over powder cards (also glued together)
-85 grains of Goex Cartridge BP

{Using the longer shell I still had a good half inch clearance form top of shell to over shot card}

Resulting in 12 o'clock hits with no departing of the smaller buckshot and creating a nice rounded triangular strike, on an eight inch shoot and see target, with a center aiming point hold. A kind of ad hoc slug, that is possible with somewhat lower black powder ballistic forces. And recoil is very easy to take with this ten pound shotgun and this black powder load. Took me a while to find something resembling success with this shotgun and bigger game loads. Number 4 birdshot was a super easy snap!

...but without some spread does it not disqualify any benefit from shooting buck and ball? Why glue the buckshot?

It does tend to keep the pellets in a tight grouping.

I found if I was too judicious in the use of glue it strikes as just one projectile.

However today the results were more like just a nice grouping of them into about 6 inches at the distances shot.

Would never have known this without these meager trials.

PS: My purpose is a close range big game animal load, and nothing else.
Earlier tests without the glue proved pretty much worthless giant groups, with the smaller buck no where near the bigger round ball on paper.

Huh, interesting. Perhaps a medium like buckshot tightly packed in cornmeal and carded would yield different results?
 
^I desired this type of ammunition for a single primary reason Plinker 777.
My often very fruitful bird and small game late evening/early afternoon hunts up here in the NE boreal forest used to be rudely interrupted by;
A. The occasional wolf pack or B. Much more often Mr. Yogi & friend(s) Hence I quickly gave up on carrying a nice quiet, accurate, and really handy 22 rimfire.
This brought out the shotguns from my closet of mostly 20 or 12 or 10 gauge.
Of course, yet again BP 10 bore is a hand load project only......and a decent & more conventional buckshot load for this one, still escapes me. ;)
