Ammo is really almost whatever you find that shoots well out of up your rig and there are tons of options. Same thing applies to scopes. I love the bushnell 4200s, and I also like the weaver tacticals, all 3x to 15x range. However, I recently went in for a Vortex Razor which I found to be excellent, but way too heavy for a trek rifle, so I resold and picked up a vortex viper pst
ffp 6-24x50. Well, I'm sold. I don't think I'll be buying any other scope from now on. Weight is good, solidly built, turrets are dead on every time, and the glass is excellent. I tend to get myself in a position to shoot out to 300-500 yards and range entry points when we setup our stand. I just write it on a sticky, pop it in a ziplock bag, toss a rock on it so I can see my ranges, and start calling. The extra magnification has come in handy, and I use the offset angled a2 open sights for anything that comes in closer than 100 yards. I can't speak highly enough about the scope and glad I took the chance on it. The illumination has come in handy on a couple of dusk and dawn shots, but I'm not sure it was critical... But nice. Congrats on the new rig and have fun!
