Just had this conversation with my brother in law.“Old fashioned” cup and core bullets have been murdering deer for over a hundred years.
Which bullet are you talking about? Speer doesn’t offer a 200 grain .358” HC bullet. Perhaps you meant the 220 FN, which is definately too hard for Herrett velocities.i found the 200 grain 35 cal hot core to be too hard when fired in a 357 Herrett (for deer). Little expansion. Designed for bigger critters and higher velocity.
I shot Hot core 200 grain circa 1990. 358 cal. For what its worth it wouldn't expand at the velocity I could drive it at 357 herrett velocity on whitetail. A 180 SSp worked MUCH better.
