Short action from late 1968 thru 1969, then long action introduced in 1970. Flatbolt SA up into 1973, and LA flatbolts from 1970 into 1973 with the rare transition hollowbolt thrown in. By 1974, its the now common roundbolt.

I had a flat bolt in 284 Winchester which I bought in 1971. The long actions were available at that time but not common. I should have kept the 284. GD
