Back when I came to Alaska in the mid 60's I killed my first moose with my old Springfield 03A3 and a factory 220 grain Silvertip. The range was about 250 to 300 yards and the bullet entered the lungs and did not exit. I think the moose went about 20 yards and laid down. Others carried 220 grain Core-Lokts and a fortunate hand loader had 220 grain Partitions. I was well armed with that old Springfield and 5 of those big 220 grain slugs in the magazine.

I may be using 168 grain TTSX bullets in the 30-06 now. But I don't see them killing much of any thing those old 220's can't kill. But, I have only killed 3 animals past 300 yards.
