I have a Henry Big Boy Steel in .357 and it has fed anything I've shoved in it whether a .357 or a .38 and has functioned both smoothly and accurately. This includes SWC, Truncated cone flat base, round nose flat point, round nose, and hollow points. All of the above in jacketed, HiTec coated, lead, and copper coated. I was shooting some long range at Quantico a couple weeks ago and let my friend shoot it, he loved it and now he has one on his list.
