In my studies of original rifles, I have only met with metal tips on the outboard end, for ramming,....twice. Both of these were of poured pewter, and both of these were on original Schreyer rifles. Most original rifles I have seen had ramrods of 3/8" diameter. If over 50. caliber, they flared at the muzzle end to 7/16". Very often, the 3/8" diameter tapered to 5/16" from the ramrod entry rearwards, where there was an iron tip designed for cleaning. As a previous post noted - for a slimmer forestock. I only do this for customers who are experienced shooters - I hate making replacement ramrods. In any case, the basic ramrod diameter should never be greater than 3/8" And the cleaning tip should always be in the bottom of the ramrod hole. Peter A. Alexander
