Black Horn powder is my in-line ml favorite. You may want to experiment with several bullets/brands and see what shoots the best. You may find too that with a particular bullet that going down or slightly up on the charge will give you better bullet groups. Just learn to seat the bullet firmly on the powder charge each time without smashing it hard and remember when you get your final combination, make a mark on your ram rod to indicate proper seating position and that way you'll always know if you've errored in your loading before a potential really bad thing could happen. I like CCI prmers and TC & Barnes bullets. Good luck and enjoy!
