Mike, your mention of 237 grain 8mm bullets brought up a painful memory for me. Painful because I no longer have the rifle. It was a beautiful Lee Sporter in 8x50R Hungarian. The rationale for having it in 8x50R must have been that the 237 grain bullet was infinitely better for game than the 212(?) grain bullet of the 303. Or, perhaps it was going to be used in a country where the military 303 was not permitted. Whatever, it was a great shooter and now I'm sorry that I let it get away.
