If ya go to Saskatchewan take some #2 Hevi also or the Remington HD stuff. BTW I'm jealous. How many of ya are going? I went up there a time or two in the past. Even got paid for a few days. That was years ago though. If you go out with some of those indians up there you'll be amazed at how well they can shoot! I wish I had the opportunities now that I had years ago. I guided for a group back in the early 80's that hunted from Canada to Mexico and lots of places in between. They offered me a full time job coordinating(and guiding) their hunting but I had too much time in the fire dept to just up and quit.
You're gonna really like the hevi shot if you remember shooting lead. It's even better in some respects. Holds great patterns. If you shoot tolling birds use a skeet or improved cylinder. For longer shots try a light modified. Real long go with improved modified. Go to the skeet range..or sporting and shoot a little hevi before you go so you know how it shoots. It's expensive but it'll really surprise you. Not many cripples!
