Most scopes seem to have good warranty's these days, Burris, Bushnell, Nikon, Leupold all have life time ones, but the best one seems to be on Vortex scopes.
Paper punching and varminting both seem to require a similar scope, but for hunting you typically will be looking at a different type of scope.
For paper punching and varminting, weight or size isn't typically an issue, so going for a big heavy "tactical" type scope with lots of bells and whistles, lots of magnification, finger turret and a huge objective isn't a problem. Where as hunting, you usually want to get a lighter smaller scope.
For a hunting scope the Ziess conquests has excellent glass and can be found at a good price by shopping around. But the Burris C4 in either 3-9 or 4.5-14 is another good option, Burris has a good reputation with their fullfield line of scopes and C4 combines the same glass but with a finger adjustable turrets and their funky but practical reticle.
For "tactical" scopes, or longer range scopes the possibilities are almost endless, budget will dictate what's best for you. But Vortex seem's to have the best value for money at the moment, but Nikon and Bushnell and others are not far behind.
If you can afford it IMO the best do everything scope will be something from the Leupold VX6 range.
