bushveld,
The .375 H&H Flanged has a head diameter of .454-.456" and the cases I need have.427-.433" head diameters. The 38-55 has about .422" head diameter, which is close enough to be safe and not require swaging the head, even though a little short. I have swaged heads before, but this is a lot more trouble than adjusting the rims (only a lathe job) and putting up with slightly short cases. I have resigned myself to possibly swaging case heads when my last bag of original cases runs out but had decided to use either 30-40 Krag or .303 British. I have 30-40 cases on hand, but also have a rifle, so I would likely buy currently available .303 cases. I do have a little .375 H&H Flanged 2 1/2" ammo but will save it in case I find a rifle. In my condition I would rather have one of those rifles than the Flanged Magnums.
Mike
