This is my daughter again but different year. It was a spot & stalk hunt in rough country. This heavy bodied muley fell to a 30-30 bullet shot through the chest organs. It would have been very difficult to haul my heavy barreled .223 around these steep canyons.
We are acquainted with a Mexican shepard who has but one rifle. Its a WW2 German mauser in 8mm. American made ammo is loaded down to 30-30 velocity but that has never been a handicap to this careful hunter. He has taken many elk with this old rifle. Shot placement is a factor which is often ignored by the shooting press.
The 64 grain Winchester bullet and 60 grain nosler Partition are genuine big game bullets. My friend loads the Nosler in his 220 Swift. I've witnessed instant death performed with broadside chest shots. Even big mulies are not armor plated.
