The answer was to use my already proven back-up rifle.
But what if I had no back up rifle?
I would then have to wait for daylight and go to the range with the banged rifle scope to see what was happening and miss the critical dawn whitetail hunting.
A laser bore sight device is made by several manufacturers.
I have seen Jim Shockey advertise the Site-Light SL-100. But seeing is believing. I will try to hunt and field test one of their models here this spring.
They make three models. The SL-100 is cost effective at $99 dollars via most retailers. The SL-150 is $160 or so. The SL-500 is military grade at over $200 and can be seen out to 100 yards.

Here is the Sight-in Rule of Thumb for 25 yards for a 1/4″ per click at 100 yard scopes:
4 clicks moves the crosshair 1 inch at 100 yards (indicated on your scope dial or caps)
Most importantly at 25 yards it takes 16 clicks to move the crosshair 1 inch.
Here is a simple method I use when bore sighting a hunting scope that has 1/4 inch per click at 100 yards:
Personally I would not hunt deer size game with a bolt action rifle that shot worse than 2 inches from a bench rest at 100 yards, but that is just me. Most new rifles are capable of so much better with the right load… so experiment. I strive for at least 1 inch groups.
Using a ballistic calculator for longer distances helps. I use www.jbmballistics.com
At longer distances, wind become a very large factor.
Good Shooting!
