I've only ever shot reloads and the non-corrosive Ukrainian ball/HP in my 527 with no feeding or extraction problems and two quite dead deer last fall.....1/2" groups with mine....... 1" or under with factory ball and a 4X Leupold......Harold
last I saw him post was he sold out and was not bringing anymore in because of retailers sourcing the ones from the USA for cheaper and he could not compete
