10 & 16 G with Green Dot

Chronograph is a chore, avoid it but had to crono some Lever Action Silhouette loads. 38/40 & 25/20. Took two Parker Hammer guns and a Trojan, 16 G & 10 G all loaded with Green Dot, & clocked them same time, interesting results.

My standard 10 G load.

10 G Federal hull cut to 2 7/8 Fold crimp. Remington SP 10 wad fiber filler. 1 1/8 oz Winchester Primer 23.5 Green Dot.
Average 1302 FPS Extreme spread 32 FPS. Clean burn very little residue in the bores.

No need to go that fast, going to cut the charge 1 grain & re-check.

16 G several hulls and loads. Two objectives, hunting load for theTrojan and absolute minimum load for clay targets to 25 yards in the O Frame Hammer gun. Note on the 16 G Society spread sheets 14.5 Green Dot is minimum GD Load listed.

For the Trojan

Cheddite new hulls 2 ¾ inches Fold crimp DR 16 wad no filler Winchester Primer 7/8 oz 14.4 Green dot. Average 1038 FPS Extreme spread 8 FPS clean burn little residue. I account the low ES to new hulls and good crimps as well as more shot and enough Powder. Use it as is.

For the 16 Hammer

Herters (Cheddite) once fired hulls 2 ¾ inches fold crimp DR 16 Wad 3/4 oz Cherrio filler. Winchester Primer 14.0 Green Dot Average 988 fps Extreme spread 138 fps. Dirty load with obvious velocity variation from the sound. It’s too light.

Herters (Cheddite) once fired hulls cut to 2 5/8 inches fold crimp DR 16 Wad no filler Winchester Primer ¾ oz 14.4 Green Dot. Average 1021 fps Extreme spread 63 fps. Much cleaner burn than 14 Grs

Same as above in New Cheddite hulls cut to 2 5/8 inches Average 1037 fps Extreme spread 45 fps.

Same as above in Remington Game Load hulls cut to 2 5/8 inches Average 1124 fps Extreme spread 11 fps. No doubt smaller internal capacity Remington increases pressure and gives the cleanest burn of all with lower ES.

Probably ought to load all 16’s with 15 grs Green dot. Skip the Remington hulls, they are in poor condition & hard find in good shape. Will load some up 15 grs chronograph and see how the recoil feels.
