T/C Triumph bullet drop?

I don't have a lot of time to go out and do the testing myself due to my job so this is why i do not know myself. I have the T/C Triumph and was wanting to know what the bullet drop is using 100 grains Pyrodex and a 250 shockwave. I have Nikon Omega scope with BDC and want to know what the BDC marks mean with my load above. I mean how to calibrate my load to the BDC.

If you got a T/C Triumph let me know what load is most accurate with yours. Even better if you shoot with my same set up what is the BDC drop points with your reticle.

I'm guessing BDC stands for something like "bullet drop compensation."

Nikon has a PDF file on this website that explains everything:

Once you've sighted in the scope using your chosen load of powder and chosen projectile, the BDC should be fairly close if you get used to using it in the way the manual explains.

The accuracy of pretty much any rifle depends on the shooter more than the rifle; few shooters can outshoot their rifle.
