Kudos to you for heading down the flintlock-hunting road :grin: !! Nothing is nearly as rewarding as harvesting meat for the table in this manner.
I would go with round-balls for two reasons. First, due to the fact that most traditionally-styled flintlock rifles have a slower rifling twist rate - typically 1 in 48" designed for round balls - the chances of stabilizing a conical bullet are pretty slim (modern muzzleloaders typically have a faster twist rate - 1 in 24" - in order to stabilize the heavier conicals... this faster twist rate will send round balls every which way). Second, it's the traditional method and well-proven to harvest game. It's also cheaper

Before you head to the field get rid of that instinctive flinch that comes with shooting a "firelock" for the first time - I myself had a hard time overcoming this nasty habit. It helps to dry-fire the weapon with a flint-shaped piece of wood in the cock in order to save on flints. While you're dry firing hold the rifle on target and concentrate on not watching the lock out of the corner of your eye, but instead focusing solely on the target/sight picture. Next step is to replace the wood with a real flint, prime the pan, and practice shooting off priming powder - not flinching. This is probably common sense, but whenever doing any of these exercises DO keep the firearm pointed in a safe direction - don't ever point it at anything you wouldn't want to shoot.
Test various loads in your rifle, and settle on one load that you stay with no matter what range you're shooting at - learn where to hold your sights in order to hit your target. I use 75 grains of ffg in my .50 with a .49 round ball - seems to be a pretty near perfect load. But this is all personal preference - you find something that works for you.
When out in the deer woods, don't prime until last minute - instead, use a feather to seal the touch-hole, keeping your main-charge nice and dry.
And always make sure that your flint is sharp and correctly aligned - nothing as bad as having your gun misfire due to a bad flint, knowing that you could have prevented it :redface: .
All the best to you, and I look forward to reading about your successful hunts, Mr. Davy Crockett
