I have shot 150 gr loads a few times just to see what it felt like and what kind of accuracy I got. In my Black Diamond XR I have to admit, with pellets the accuracy was very good. The recoil on the other hand was not something I would want to spend all day on the range with. Even 120 grains of loose powder is a good STRONG load. More then I care to shoot time after time.

I have been shooting muzzleloaders for more years then I care to mention. We started out with traditional rifles shooting 80 grains of Goex and when we saw the first add in a magazine for an inline rifle, we laughed about it. Knight had a MK-85 and it was supposed to be the end to all muzzleloader problems. We were killing deer so fast with the old traditional we ignored all of that.

When I finally go to the inline part of my life I had to shoot them big loads. But since, I have tuned them loads down to 80 - 110 grains and find that is more then enough for all my needs and the accuracy is great.
