http://www.midsouthshooterssupply.co...u=000156031111 There you go. That's about as close as you will find to what you are after, but that isn't the end of the story. You can have fun finishing and putting that one together and it should be a good rifle, but the barrel it comes with is most definitely for round balls. Who's to say you can't have some fun and get the feel of the rifle using round ball.
But, you will need an aftermarket barrel with a fast twist of 1:24 to 1:28 to shoot conicals and the faster twist would probably be better if going for long ranges. I'm sure such barrels are available for that rifle, I'm just not sure where... maybe someone else can chime in with a suggestion. You will also need a high quality sight.
You could try the 1:32" drop in barrel for the Hunter but it probably won't get you where you want to go. A 1:32 twist would likely not do nearly as well as a faster twist model. You are also going to be looking at heavy conicals for the longer ranges. They will shoot in a rainbow arc but pack one heckuva punch even way out there.
Another piece of advice would be to call Doc White and see if he might have something to interest you.

Oh, you might also call Lee Shaver and see if he could help you out. I would try to become a little more educated before calling him though.
