O yea! Shes shoot 22s alot and understands all of it. She isnt worried about it at all, its more me over thinking it im sure. Powder??? Im not sure i shoot imr mostly in my loads. Have never had any trouble out of it and it preforms great. I was just currious to know if some one new a load that they would share to cut down on some of the test stages. But then again thats part of the fun of finding loads that ll shoot right......
