RE: 17. HMR
having considerable experence with the 17 HMR in a marlin bolt action with a3-9x redfeild scope i would say the maximum effective range would be around 200 yard max. 150 would be a goodrange to stick with because the little bullets tend to drop a good amount after that. If you pracitse at the rang a lot with your gun and find out where it hits at different ranges making shots out to, and beyond 200 yerds is not impossable.
