170 grain Silvertips are a classic load in this caliber and perform beyond their ballistic chart stats on game. They are my go-to bullet in the .30-30. A couple of loads shoot marginally more accurate, but I am with H4831 on this one. Bullet performance on game is the key here and the Silvertips are tried and true.
Yes, starting in the 1930s, if not before, the Winchester Silvertip bullets were certainly a western tradition. With the higher power advertising of the big US company, the Silvertips were the ones others were judged by.
The great depression of the 1930s was the period when vast numbers of people living in northern Canada survived by living, year around, on wild meat.
The principle game animal was moose, with some scattered areas having a good supply of elk, mixed in.
The majority of these animals were shot with the 30-30, with maybe 95% of them with Dominion ammunition. The Canadian hunters would have used more Silvertips, except they probably cost a bit more and were not available in the little country stores.
Here is the type of ammo used throughout this great survival time. This exact same CIL 30-30 ammunition was paid for by the federal government and distributed to the Natives in the arctic, through the RCMP offices, until at least the end of the 1950s.
So, to the original poster, this is why we feel safe in reccommending 170 grain Silvertip amunition, for your anticipated shooting of moose with them.
The famous Dominion line of ammunition is long gone.
