I hunted big game for many years with a Model 94 in .32 Win Spl. (ballistic equivalent to the thutty thutty) I can attest it will kill any deer you can see to hit within 100 yards.
I don't know why so many people place such a restricted distance on the killing power of the 30-30 class, or less, rifles.
Of the true stories that I know have really happened over the years, I will give two examples.
In Manitoba in homestead days a group of men were working with their teams of horses at a gravel pit in the winter. A moose appeared at a known distance of a quarter mile. One of the men was a Native Indian and he stated that if the moose showed up the next day, he would kill him. The others all laughed at him, telling him the distance was 440 yards. "I know," said the Native, "I'll shoot him."
The next morning the Indian brought his rifle with him, a Winchester 44-40!
As if on schedule, at noon the moose appeared, same place. The Native took a long, thought out aim, shot and killed the animal, with the one shot!
In homestead Saskatchewan was an exceptionally good hunter who used an 1894 Winchester, in 32 Special calibre. In the winter he took his team and sleigh to a field, where he had a stack of hay. He loaded the hay, then climbed up on the hayrack to go home. He looked and saw a moose beyond the end of the field. He knew his haystack was 300 yards from the end of the field and he said the moose was about thirty yards beyond the field.
He laid down on his load of hay, made a mental calculation of elevation needed, carefully squeezed off a shot and killed the moose.
Regardless what you may say about what I have written, I know the two events happened, exactly as I have written.
