The way I solved my requirement for long range muzzleloader is a T/C Omega (no longer made but available), Blackhorn 209 powder and 175 grain .357 Duplex Sabot
www.prbullet.com . Weaver one piece base with XS Sights receiver sight for states that do not allow scopes or scope for states that allow them. Need a taller front sight for receiver sight. Use an MMP BBSB Ballistic Bridge sub base under the Duplex sabot. If you have accuracy problems with T/C muzzleloaders, check for runout between the QLC and the rifled portion of the barrel. QLC is an oversized portion of the muzzle to aid loading. I have seen the QLC so poorly done you can see the misalignment with your eye. TC will replace the barrel. For a quicker reload, I replace the PR bullet black sabot with a Crushed Rib sabot. Not as accurate but much quicker to load for a second shot.
