I am thinking about buying a set of the Burris Zee rings. This is for a varmint rifle in 223 Remington cartridge. The rifle will not see heavy duty use. It will be used for ground hog hunting only. The rifle is a Savage Model 12 VLP-DBM. The scope is a Swarovski 6X18 power A line scope. What do you guys think about these rings for the usage I described?? Thanks, Tom.
