Good morning. If discussions about TSS shot are forbidden, please remove.
Some folks need/want non-lead shot options. I have performed a bit of research with very little information forthcoming about using TSS in traditional smoothbores. Folks say it will ruin you barrel or the plastic shotgun wads will melt and leave nasty residue in your barrel. Well, I ran a couple of test on my Chambers .62 English officers fusil with a 41” barrel which is jug choked.
I acquired some #9 TSS, some non-slit plastic 20 gauge shotgun wads designed for TSS and a plastic shotgun wad slitter.
I compared weight to volume for TSS with a digital scale and my standard powder measure. I found:
1 ounce (by weight) of TSS = 40 grains (by volume) in my powder measure
1.5 oz ( by weight) of TSS = 60 grains (by volume)
1.75 oz ( by weight) of TSS = 70 grains ( by volume)
I tested several loads but here is my best load so far: (30 yards distance).
70 grains FFG Goex powder
1 1/8” nitro card edge lubed with Mr. Flintlock lube
1 1/8” wool felt wad lightly lubed with Mr. Flintlock lube
1 plastic shotgun wad (for TSS) slit fully and trimmed to length of shot column
70 grains #9 TSS
1 over shot card
My target was a large sheet of light cardboard with a lovely turkey image drawn on it. Turkey’s neck is about 10” for perspective.
As you can see, the pattern is pretty good at 30 yards. This is only the results of my testing with my flintlock smoothbore. Your mileage may vary.
No evidence of burning/melting plastic wads.
No evidence of plastic residue in barrel.
Wads have powder residue staining but could be used again.
No evidence of TSS dimpling the wads.
No evidence of damage to the barrel.
Jug choke did not appear to have influenced the pattern using plastic shotgun wads.
