Changed to BH 209 for my T/C G-2 in 50 cal. this year.
For 3 years I battled with the 2nd shot in the G-2, it couldn't be loaded ( without cleaning ). Called T/C tech, nothing they told me worked. Dropped down to 44 cal bullets with black sabot, still didn't work well. I tried every powder, pellet & bullet I could get, still nothing worked well. Power Belts would load, but didn't shoot well. Couldn't get any BH 209 last year to try, everyone was sold out. This year I got my hands on some early and tried it. It worked fantastic. Went back to the .45 cal bullet with yellow sabot, like it was supposed to shoot. The 3rd, 4th & 5th shots all went down with ease in practice and shot very well. BH 209 solved the problem in my G-2.
For my T/C Black Diamond in S/S. It still love 2 Pyrodex pellets with a T/C black sabot w/ 240 gr XTP. When I run out of the pellets I'll probable change it over to BH 209. Hopefully it will shoot as good as it does with the pellets.
