What are the proper names of the .375 H & H Magnum which are Rimmed?°
.375 Super Flanged?
.375 H & H Flanged?

Plus the .300 H & H Magnum rimmed version?
.30 Super Flanged ?
.300 H & H Flanged?

I used to know. But have forgotten. Also sometimes I uses different name as people recognise eg a H&H nomenclature more than the real one.
