The Army changed to ball powder....
In 1964 the Army switched from IMR extruded powder to Olin ball powder. In October, 1967 the Ichord Subcommittee investigated the problem that our soldiers were having with their M-16s. There were 31 faults found, but most of the focus was on the switch from IMR 8208 to Olin Ball Powder.
As far as GI 322 being close kin to 8208.....maybe, but I don't think so. The GI 322 seemed slower and it definitely broke down faster and has led to several house fires. Jack Sutton has probably shot more GI 322 than anyone here; so, maybe he will chime in and tell his experience with it. James
