Which style do you think performs better at target and hunting? Which do you find more pleasant to shoot. Just looking for opinions. Might get a new gun for Christmas!
If you want a capable first gun to become accustomed to shoot, the Lyman/Investarms Deerstalker is an excellent choice. It may get you derision from the snooty purists, with it's rubber buttpad & nowhere near authentic styling, but it is easy to shoot and maintain & has the potential to be amazingly accurate, and very comfortable to shoot all day.
I grew up shooting an assortment of original rifles, and already had several percussion and flint rifles, when I found my Lyman Deerstalker. They quit listing the lefthanded .54 cal. flint model in the Lyman catalog, a few years ago, but a vendor had one on-line, so I bought it.
Break-in was quick and working up an accurate load was also quick and painless. Accuracy was sufficient, that it became my 'Grapefruit Slayer', excelling at dispatching the bags of excess grapefruit from my parents' trees. At 100 yards, no grapefruit was safe, and when the ranch was sold & grapefruit were no more, clay pigeons, or small water balloons suffice.
Some of the snootier shooters at my range asked me why I bothered with that "cheap, old fashioned junk". After successively busting a line of a dozen grapefruit at the 100 yard berm, the only questions became: " Hey, can I try it?"
.54 cal is preferred. It seems easier to work up accurate loads and the heavier ball retains more energy at 100 yards than my .50 cal's.
You'll go on to get other, fancier & pricier guns in the future, but the Deerstalker will give you a solid foundation for shooting either flint or percussion that will carry over to everything else you'll ever shoot.
