Juding only by your total posts on this site,,and deriving your experiance from them,,,,,the Lyman GPR would/could be the best bet for how do I say?"" "an experianced novice?" The GPR/GPH allows proper barrel twist, and interchange-ability. For some one seaching for traditional cap-lock style shooting and the option for.(with gph fast-twist barrels minnie or maxi ball shooting with proper accuracy),. I hope that in your "studies" for what option of hunting/shooting style you prefer, you try "fit" of the two gun's you have listed.
A trip to any nation wide dealer of firearms will allow you to handle and feel for comfort both of the gun's you have listed and those listed by others.
As sharp's posted T/C is a good gun,,and he also said he's won a few matches with a GPR. I shoot a Lyman//not a great plains model. I have made meat with my gun,,I have lost matches to great plains models. I can and will say a T/C has never shot better than my lyman,,and I have owned T/C.
A/H ?,, well thats a good gun. Are they better? Yes. Are they for the novice? No. If ya cain't clean or study proper prb combos A/H ain't for you. If you like fit and have time too study and perfect your shooting, then a better gun might be the better choice
