Which powder for .243 and .270

IMR 4350 is my first choice for my 243 ,with 85 to 100 grain bullets it will always do the trick.The 270 WSM likes it, as does the 22-250, and the 280 Ackley. Never could get a good load for the 25-06 with it though.
 
IMR 4350 works for me, too, for both 65gr Horn. VMax and 100gr Sierra SPBT. Tried the Hornady 87gr, but it went all over the paper. STILL haven't figured THAT one out!

And if only one powder were allowed for the .243 Winchester I guess it would be IMR-4350 and for the same reason as above.

I fully agree with GC.
