Addressing the member with the cross manifold. Cool! V509 , I owned years ago 23 T Bucket. Classic red with black top. 327 Vette engine.
A fun ride.
Back to TK 2000 shotgun .
First off I found the suggested Knight loads were not that great in patterning. Plus kicked liked everyone who has owned them and used their suggested load. A regular shotgun with the same Knight load would rock one’s shoulder as well.
I’ve gone from using a 1.75 oz load to 1.5/8 oz load. Using #9TSS-18gm cc.
I see no need to use more than 1 5/8oz.
Initially I used a Ranger Elite wad .
Now I use a TPS-46 wad. A superior wads for TSS.
Both are BPI products.
IF you use TSS make sure you use a wad that is approved for TSS.
I’m not sure that the TK is approved for steel shot. The BPI WADS take care of this issue.
Another overlooked situation of wads and their performance is the wad wall thickness. A thicker wad wall in essence can be the same as a tightening a choke. Example :
Ranger Elite wall .040
TPS-46 wall .055
Load developing. Poor pattern.
Can be not enough powder for the shot load or conversely not enough shot for the powder. Other factors of course such as wad seal etc.
My current TK2000 turkey load.
90 Black MZ.
Lubed wool wad. OP
TPS-46 wad
3/8” 20 ga cork wads inserted into TPS-46 ( one can use 3 - 1/8“ wads, I use a 1/8” & 1/4”)
1-5/8 oz TSS #9
Buffer to fill the shot filled wad.
( How much buffer? Put the wad in a cylinder choke tube or equivalent tube. Add the filler wads. Add the shot. Start adding the buffer. Tapping or vibrating the wad. Add buffer until the shot starts to show at the top of the wad. Don’t let the shot raise past the wad. Once done dump into a scale and weigh. Measure the difference and that’s how much buffer to use for this muzzleloader load.)
OSC. Over shot card.
Prime, aim , pull trigger. Dead turkey.
A great source for TSS shot. Will send 1lb or plus.
