Don't know much about brands but definitly would go with the type you insert in the end of the barrel and has a piece that sticks up even with your scope. Those lasers are crap my cousin had to move a .450 marlin 74 clicks to the left and 52 clicks up just to sight the rifle in after having it laser boer-sighted.
The magnetic boresighter by Leupold is suppose to be excellent. I have never used a boresighter of any type because I have all bolt actions and can look through the bore with the bolt out and get my gun on paper that way. I then shoot at 50 yds to get close before moving to 100 and beyond. This will get you real close quickly if you are using a bolt action.
Hinge-cutting serves several purposes in regard to improving both whitetail habitat and your hunting experience. There are two main types of hinge cuts including a cut for screening and funnels and a cut for bedding. Hinge cuts for screening and funnels should be done somewhere between the knee and waist to block a deer's vision as well as block a travel path. Hinge cuts for bedding should be done around chest high so that there is room for a deer to bed underneath.
