Well that's about a $460 rifle, retail. So
you dun good.
The trade rifle is a 1:48 twist, and will shoot roundball as well as conical. It should shoot both well enough for targets and big game.
You may want to order a thin, silver, front sight post from Track of The Wolf.
https://www.trackofthewolf.com/Categories/PartDetail.aspx/874/6/FS-TC-TTB Italian muzzle loading rifles more often than not, come with a rather thick front sight, and a bullseye on a target is like looking at a nickle balanced on the top of a 2x4.
So to get the most out of the accuracy you can go to a thinner sight, and get much better results. Plus it's silver so reflects light better in the woods, and in low light. The tall one is used, for you first to get your windage, left/right correct. Then you use a hand file to slowly remove silver from the top, by filing only lengthwise, to raise your point of aim until you are "on" at your preferred max range. THEN all you do is practice.
I'd recommend you start out with 3Fg black powder (since the powder substitutes are notorious for poor ignition in flinters) and use it for BOTH the main charge and the priming charge. It keeps thinks simpler when you only use one powder for both, and I always found 4Fg in any of my flintlocks simply soaked up moisture from the air, and didn't help ignition.
I'd also recommend you simply use a round ball, patched with
linen and a moderate charge of 70-80 grains of powder. Plenty of impact on deer out to 100 yards. YES you will meet fellows who shoot .50 caliber, 385 grain conicals with 110 grains of powder, but what you won't see is the huge bruises they get, and the flinch from the recoil that they develop, all the while the deer not knowing it's any deader than when hit with a round ball with moderate load.
OH Italian factory rifles are also notorious for crappy quality ramrods when they come with wooden rods, so I'd suggest you get a couple 3/8" rods, and cut them to length and sand (they are always a bit too fat) and stain them
