Slithery, I have to add this because for years in Saskatchewan and Alberta I used the traditional old Silvertip Winchester ammo (Not Ballistic Silvertip) for deer hunting.
In 308 and 30-30 I had very effective expansion.
I recommend these rounds whole-heartedly for whitetail deer.
(Just a side note, Once I had to use Remington 308 Core-Lokt 150 grain SP in 308, and it was very slightly more accurate on paper, but the Remy and Winchester rounds,are equally effective on deer)
There was something else, I will tell you, about when I used the Winchester Silvertip 150 grain 30-30 round!
The damage to the chest cavity was extensive.....not only smashing heart and one and a half lungs, BUT the forward 5-6 inches of tenderlions were useless.
(Totally smashed by lead fragments!)
I was flabbergasted by the damage in the chest cavity.
It was as if, a little grenade exploded in there...
