I have an 88 in 375 H&H and also have a Win 101 in 30-06. Both are rimless cases and function perfectly. If the Heym has scope bases and is scoped I can't see why it wouldn't be a very delightful gun to use. It would be excellant for african game from Kudu down. The Heym's are exceptionally trim and point marvelously. Very quick. Would be handy in thick brush also.
