I just bought an H & R Handi-rifle in .44 Rem Mag. I need some suggestions on how to zero the scope to be in the kill zone on southern whitetails out to 150 yds or so. I'm using 250 gr. Winchester Platinum ammo. I zeroed my Rem .270 BDL about 1" high at 100 yds and I've had good luck withit out to about 200 yds. I've checked several ballistics tables and there is very little agreement between these tables and they make no distinction between handguns and rifles.
