1) How high should I zero my guns at 100 before heading to the 300 yard range? START AT ONE INCH HIGH AT 100 AND ADJUST AS NEEDED.

2) What type of target at 300 yards? ANOTHER VOTE FOR REDFIELD TARGETS.

3) How much power do I need in a spotting scope to see holes at 300 yards? DEPENDS ON TARGET-USE SAME SPOTTING SCOPE YOU WILL USE IN THE FIELD AND SAVE MONEY.

4) 80 gr or 100 gr .243 bullets at 300 yards? 90, 95 OR 100 GRAIN FOR BIG DEER AT THAT DISTANCE.

BEST OF LUCK
