My wife and I have been using .243 Winchesters for deer and antelope for a few years now. We,ve been using 100 grain Hornady Interlocks and while that bullet kills just fine,
***in many cases it stays inside the chest cavity and doesn't exit.***
Because of this, it doesn't leave much of a blood trail. We've switched to 95 grain Nosler Partitions and hopefully now we'll get the complete pass through we're looking for.
Interesting ! ! Hornady must have made some changes to the 100 hsp. 'WHEN" I used them I never caught one.
The only reason I changed was Midway sold bulk Rem PSPCL much cheaper -*-*-> those older CL were tougher than Hornady.
