RE: Have you considered ............
The problem you find is many people who are uninformed fall in to the hype of muzzleloaders and their "game taking" ability. They are reading magazines and watching TV hunting shows where these paid "experts" are bragging about the need for their 150 grain load and their sponsors bullet, their other sponsors rifle, and their other sponsors optics. Then we even have them selling us powder. Buy this powder because my names on it. It is the best out there.
Before all these magnum capable rifles were around. Most of us shot from 70-100 grains of powder. And we still hunted and took the same animals they are taking today with their 150 grain charges. Now I am not saying that the magnum muzzleloader does not have its place. It does. If I were hunting large game at long distances then the stronger the powder charge the rifle shoots, could be a real advantage. Even light game at extreme distance, the stronger charges might be a plus. But is that to say a skilled shooter could not do the same with a 100 grains charge? For what most people hunt and the distances we shoot at, 75-110 grains of powder is more then enough. Sabotloader proved that this elk season with his 300 grain Nosler and110 grain charge, at I believe 176 yards approximately.
When our forefathers were wandering this land shooting game to stay alive, they often times used a simple roundball and a very light powder charge. Why? Powder was hard to come by. So was lead in some cases. They really had to watch what supplies they shot. They were more into getting close to their game and making their shot count.
Although let me say this.. hunt with what gives you the most confidence in yourself and your rifle.
