In the good old days a recommended .222 load was a full (scooped) CASE of 4895 carded off and then seat the 52 grain hot shooting, flat base bullet. We all had crewcuts then, or of you were a hotshot, you got a Flat Top! There was no need to say IMR , there was only Dupont powders on the back shelf at the hardware store...We all survived, somehow.
