See the discussion recently on "question for bullet casters". Good relevant info while deciding. My relatively small experience with semi autos and cast is limited mostly to .45 acp. The only consistently good feeding bullet was a truncated cone style. Even round nose would hang up sometimes in the cheaper .45s. If I were to hunt with a semi-auto and cast I would get a truncated cone and send it to be hollow pointed. Several services sell the hollow pointing service to your mold or you can buy a complete mold already hollow pointed. Many configurations with some mold chambers left un-altered. I would test air cooled as well as water dropped. Water dropped are very hard and usually act as solid in my experience. Hollow pointing may help but I would test. Most revolver cast hunting has the large flat meplat and rely on caliber to do the work. Good luck! Keep us posted on what you find and decide.
