Lets just say his hand load is a 140 gr sst
and
lets just say he's just over 2700fps
If this is the case or close and he's 6 inches high at 100yrds he'll have roughly a 350yrd zero which will put him just over 8" high at 200 yrds.
Even if he's using a standard interlock type 100fps slower he's still zeroing about 320 yrds and at 6" high at 100 puts him over 7" high at 200
