Let me be more clear about the flintlock season. As if the slower ignition wouldn't be handicap enough. It will also only be legal to shoot a PRB. This will restrict the range quite a bit compared to a modern inline shooting BH 209, and a modern bullet like a Thor with peep sights.
I know guys who are accurate at 200yds with that setup, and the bullet still has the energy to kill an elk.
The flintlock with primitive sights is at best a 100yd gun if you have young vision. If it's a .50cal you better be even closer with a PRB. Energy drops really fast past 50yds.
Then you also have the problem of keeping the powder dry during the wet Sept month.
As for the compound bow? 80yd elk kills are becoming common now. Not what the DOW had in mind when they handed out a whole month during the rut for bow hunters.
