So my scope came in and I mounted it on my (only) rifle. I still have to sight & zero it. The rifle has a bi-pod. Which should I do? Get a rear bag (kitty litter?), boresight it (Can you even see a target through a a .22 barrel?), zero it, and walk it out to 100 yards? OR; Should I just buy a (good) muzzle laser, get my 50 and then my 100 yard zeros? Which would you rather do?
