In short, yes you can use loose powder, in fact, I would recommend it. I have found up to a 10% variance in both Pyrodex and 777 pellets. If you want to fine-tune your rifle to shoot consistently beyond 200 yards stick with loose powder and purchase a good measuring device. Experiment with different weight bullets. I have found that 100 grain of loose 777 and Powerbelt 240 grain bullets shoot best in my ML.
