I decided to save a little money on scope bases and rings when I bought my Savage 12FV in .223. My father told me that the bases really won't make a difference as long as they hold everything securely. I spent about $25 all together on the bases and rings. The rifle will consistently shoot 1" groups at 100 yds (I know it's capable of better but i tend to shake a little.) My question is, should I sink the extra cash and replace the cheap bases or will the ones I have be ok? Do expensive bases and rings really affect the scope holding zero that much?
