My first is my favorite. Not exactly a tack driver. Rem 7600 in 30-06. They say you never forget your first. It has taken many a whitetail and it always finds its mark exactly where I expected it to.
New favorite is a Marlin lever 30-30 i gave my son. It groups 1-1/2" at 100yds and has the absolute sweetest trigger of any firearm I have ever owned. Not to mention has plenty of power to drop anything I have hunted yet it has very little recoil. Just a pleasure to shoot. Glad my boy has it now.
Concentrated power is not rendered harmless by the good intentions of those who create it.
