i have a savage model 12 varmint rifle with a nikon 6-18x40sf fine cross hair with dot. at this time just getting started with it, so I have Remington 45g JHP around 4000fps. I went to Nikon spot on ballistics table. I thought about sighting in to be dead on at 200y. Question is would it be better to leave it as is and dial up to the dials to range or sight in for point blank range? Which is about 313y, or Does it matter either way, or easier with the point blank sight in? At this time not hunting just learning to to shoot LR with lighter and least expensive with some reach. Will reload in future Some suggestions at this time would be great. I realize heavier bullets would be better, but its all I got at the moment, gonna go shoot with the kids this next week. Happy Fathers Day to all.
