I have a bullet mould for a 286 gr.
lead bullet for my 35 Whelen.
I am betting that with lino type or Lyman #2 alloy that it should really penetrate well.

One of my neighbors told me that they have a nocturnal black bear that they are nervous about on their property. She says that by looking at trail cam pictures it would weigh 600 lbs live weight.

There is only one kind of dead, but there are many different kinds of wounded.
