Yea...Shoot them with 150 grains...Take a video, I need a good laugh...
How easy they are to load depends upon which ML you have, there are no industry standards on the bore diameter of ML...
I shoot 250s and that's all you need for whitetails...90gr FFF Goex, sight in 2 1/2 inches high at 100 yards and I'm 2 1/2 low at 150...
I always clean between shots and use loose powder, remember you are handloading...Work with 80-120 grains of powder and see what your gun likes the best...There is no need to use 150 grains of powder....
