Hard to ignite powders like smokeless will and Blackhorn is a lot like smokeless, so yes if not compressed tightly it will hangfire. Agree, it would not be the best powder for conicals. In fact if you read the brochure here:

you will see this which leads me to believe that conicals will not shoot well with Blackhorn. Chap

Has any one ever tried the red high pressure[Crush Rib]sabot with BH209? Looks like it might be OK.Lee

The easy fix to using conicals with BH209 is to pack the powder slightly with a fiber base wad, then seat the bullet tight against the wad. I have ALWAYS gotten more consistant velocity and accuracy with any powder and conicals with base wads.

Sounds reasonable I have all ways gotten more consistant results with a wad too.

Toby Bridges just wrote about using the red crush ribs in his knight and has great one hole groups with harvester 300gr pt golds.

Tried it wont work in my Triumph, but I get really good groups with SW[all] and with HPH24 and the 250 and 300gr Gold Dots. going to try the 250 and 260 gr XTP and Speer next.

I have shot another can of powder now and have learned a few things. it prefers the same bullets this particular gun always has, the Red Crush Rib sabot that was to tight and would not group before still wont the best it would do is 3 " and it is tighter than the HPH 24 which shoots one hole groups with 250gr Gold Dot and I have not found any other load that shoots 1/2 inch groups like 110gr of BH and the 24 sabot with a 250 GD. Most groups run 1 to 2 inches with the exception of SW and GD it likes allSW especally the 200 gr and gets 2200 fps as well as a one inch groupwith 120 gr since the pressure is close to the same as Pyrodex I am thinking about taking the load up a bit. Any thoughts on that? I am more worried about how well the bullet will hold together than anything else it has work well for me on boar and deer at 2100 fps but I am not sure just how muchfaster I can push itwith out having it fragment.
In conclusion it appears to me that to tight a sabot or it just dont like Crush Ribs not sure which but the Crush Ribs shoot real well with 777 problem is I lapped the barrel a bit cause it was kind of tight just before the BH came. Lee

have you tried any of the barnes bullets in your tc? I'm wanting to shoot the tmz but i don't know how it will load and shoot the bh209.

i believe i'm going with the harvester's in my knights. i'm going to compair that red crush rib to the black.

Yes they shoot extremly well[3/4 inch group] when there is no wind and I am shooting well but they are overly expensive so I only shoot themrarely. The 250 gr Gold Dots shoot just as well so do the Shock Waves with BH 209 finding the right sabot seems to be the most important thing. Lee

did you use the blue ezload sabots with the tmz?
