Thread: Drop chart help

I’ve never had a Chronograph but am fortunate to be able to verify on a large plate at 565yds.

I zero at 100yds.

Gestimate velocity and put it into my app to get me onto the plate.

Tutu with the velocity to get the right dial up reqd to get on the bull and save it.

Drop chart done.

No reason you can’t do the same with 100 yd zero and verify at 320 on a tall target ? Unless I’m missing something.

assumably your load is "somewhat normal" off top off head 44.5grns will be below max but above midpoint..so SHOULD BE CLOSE TO the approximate many variables of the time this chart was made...if its hotish load it will be closer to the .30/06 150grn line
either way it shows how your 320yards its entirely doable WITHOUT PISSING AROUND.....
if someone dissagrees,feel free to post up two different curve picture drop charts with velocity at half way and max for approxamately that load..... difference in real world will be stuff all.
