RE: Like your TC Firestorm?
Not an expert by any means, I've had this rfle for a bit more than three months. I got it specifically for the PA flintlock deer season which requires"traditional" style FL with open sites. The Firestorm is anything but traditional but it has the shape of older weapons so it qualifies.
I like the T/C quality and that was a big reason for getting it. I also have an Encore. It is easy to take down and clean up with the removable breech plug. The trigger is a bit heavy, and I may send it back for some work. I understand T/C will lighten it under warranty.
I had it set up with 338 gr Powerbelt over 100 gr of loose T7. Sighted for an inch high at 5o yards which gave it the range I need in the woods where I hunt. The eyes aren't so good for any long shooting with open sites anyway. The only thing I don't like about this load is the cost.
Right now I'm playing around with 245 gr Buffalo Ballets which look like they may work out. Also have shot 370 gr maxi hunter which also seems promising. Bottom line is I haven't settled on anything yet.
I've not used pellets as I have heard they don't work well, and you need to duplex a bit of powder. Given that I didn't see the point.
