Lyman #314299 / 200 grain is a good choice. Also, a non-cast bullet tip: There is a fair selection of jacketed for the 7.65 Mauser/303 British, but J. Barsness mentioned in a article a couple years back, that on an African hunt one of the guys had a 303 British that he shot .30 caliber Nosler Partitions in. The construction of the bullet, with lead exposed at the back end, allowed the bullet to "bump up" and shoot in the slighty larger caliber w/out a hitch. I plan to try that in my two 7.65 mausers.
