Load Data for AA1680
I need some help with load data for 1680. I have a ton of 170 gr round nose and I am looking for a good subsonic load using 1680 and a 10.5 tp555 barrel with the port in the pistol position. I am also interested in any other data for 150'S,168's,180's, 200's and 220's using 1680. I have settled on my light load of 130 grain speer HP's using 19 grs of 1680. Functioning has been perfect, accuracy has been just under an inch, but I have not had a chance to Chrony them yet. Any help would be greatly appreicated. Thanks Rob
