A buddy of mine came across a pound of R11....unopened. He said he has looked high and low for any load data with no luck to speak of, which can be expected since it was discontinued in the early 70's. He was hoping to use it for .308, 30-06 and .204. I found one of my old Lyman books from 1967, gave it to him and said have at it. He did find load data for the .308 and '06 and also found some for the 222 Rem Mag. He knows the parent case for the 204 is the 222 RM and asked if it would be possible to use the 222 RM data in the 204. I compared the two cases and they are quite similar other than a 7* difference in shoulder angle. Case water volume is within .1 between the two cases also. I told him I'm not sure if its safe or not, but suggested maybe he could start at the same starting load for a 40gr bullet, which I believe was 24grs. I told him I would post on here and get some input. It doesn't sound dangerous, but I may be missing something very obvious.
So, is this a bad idea?
As always, thanks for any input.
