proper drop for a 32 grain Blitking?

Hey guys,
I've been tinkering around trying to figure out how much these 32 SBK's drop at different yardages. At 100 yards it is set at approx .5" high of bullseye. When I shot at 200 yards, it was .5" low and at 300 yards it was about 4 inches low. Does this sound about right? Or should I repeat it?

I would come up a click or two at 100, Set it .75 to 1" high at 100. At 200 you will be right on, possibly .25 high. Then at 300 it should continue to be 3.5 to 4 inches low. Get a nice comfortable bench and shoot 5 shot groups at all ranges. Do a wipe down of the bore between each group. A boar snake or just a few dry patches to remove fouling. A good cleaning and then repeat the 3 group string. Take your time let the barrel cool a bit when working those groups.

You don't mention MV so I assumed 4000 fps. This is from QuickTarget. HoB is 1.5", zero is 200 yards.
·Yards fps in.
