I shoot a TC and use BH 209, typically a 100 g. Some TC have a false muzzle and they can be a issue with accuracy if not concentric to the bore and it can be hard to tell just by looking, in fact i don't know how you can tell?
Ramrod is a poor name for a pushstick, hint, ramming is not the best, a steady push to make sure the projectile is tight to the powder, marking your rod, like you said, is a good idea.
