I am building my first long range rifle, and the time has come to buy a scope. I am on a pretty limited budget, as a poor college student. Right now I am looking at the Vortex Viper HS-T. My question is, what would I gain by going with a FFP reticle? Would it be worth the extra $2-300? The rifle will be used for long range target shooting, and deer and elk at all ranges. Thanks in advance for your help.
