Problem with accuracy when using less than 150 grains
I was talking to my nieces' husband this evening about various firearm and hunting topics and he related to me that on his muzzleloader (which I believe he said was a Thompson Omega) he could just not seem to get it to sight in correctly unless he used 150 grains of propellent.
He said that he is using the preformed pellets and that when he first tried to get the gun sighted in, that no matter how much he adjusted the elevation on his scope, the impact of his shots were always EXTREMELY low on the target, i.e. below the point of aim. This was when he was using only 2 pellets, i.e. 100 grains.
He said that subsequently he attempted shooting at the same target at the same distance BUT with 3 pellets, i.e. 150 grains and after adjusting the scope to the proper setting, the gun placed the shots at the correct vertical position on target.
So my question is, is it mandatory on some of the newer 150 grain rated muzzleloaders to use 150 grains of propellent in order for them to get correct shot placement ?
