Well, I've got the oddball 1950 R that loves the Remington 100's, and won't shoot 87's. My buddy recently inherited 10-15 boxes of the 100 CL's so I'm set for life with them. The 87's we loaded for the R that didn't shoot well, shot wonderful in two of my other 250's, so I'll stick with them till I run out. My 87's were the Speer's.
