I moved to QUEBEC from Alberta when I was a kid and started hunting with my cousins and uncles for moose every year. There where more 303 enfields in camp then everything else combined. Some sporterized some garage modified and a Mark4s as is.

There was always 8-12 of us in camp and the list of calibers over the years. There was some evolution over the years but by memory. There was a trend to "upgrade" from the 303 / 30-30 to the 7mm Rem mag.
6x 303
4x 7mm Rem mag
2x 30-30
1x 35 Rem
1x 270
1x 308
1x 300 Weatherby
1x 356 Winchester
1x 30-06
