welcome to the wonderful world of rockbanging ... now that you're hooked, I hope you don't plan to waste your money on useless junk like groceries and mortgage payments ... by the way, don't get worried 'cause your co- workers think you're a little weird when you get excited by sharp rocks ... they just don't 'get it.'
:haha:
don't get too excited about "big lead conicals..." although your T/C barrel is most probably a 1:48 twist, which will stabilize both conical and roundball well, you don't really gain (in my opinion, anyway) any great advantage by putting more lead downrange ... depends on what you're hunting ...
if you're going after the elusive X-ring, shoot roundball. it costs less (in lead, and in powder) and you'll see less by way of felt recoil. This way, you can get more range time, shoot more shots, and become more proficient. (by the way, once you get a few X-rings, they make a nice blanket, if you skin them out properly)...
if you're looking to put Bambi into little white packages, do not fall victim to the siren song of what many call 'magnumitis.' ... this is the mistaken assumption that the mechanism of all things which go 'bang' is the same - it's not. a modern centerfire rifle projectile hits the flesh at a velocity which is, as a practical matter, unattainable in a muzzleloader, and when it does, it sets up a shockwave through the tissue, which causes shock and eventual death.
blackpowder guns have a different mechanism - basically, you put a big hole in Bambi, after which blood pressure falls to zero and the animal looses consciousness and collapses, and exsanguination follows.
so, if you're burning charcoal in your powder, make a bigger hole... not a faster hole or a heavier hole ... if I had it to do over, i'd still have my T/C renegade, but it would have a .54 or a .58 barrel.
OK - now you're smart ... we can continue with whether the flint goes bevel up or bevel down, and whether you should use lead or leather for your flint wrap ... stroke your chin and nod knowingly...
mind you, these are just the free opinions of one guy ... no doubt worth what you just paid...
good luck, and make good smoke!
