Same point of impact for 49 grain bullet and 33.95 gr JSB At 100 yards? Weird.

I was shooting upstate at my range this weekend. I pretty much only shoot JSB King Heavy 33.95 gr .25 cal out of my condor ss. My JSB pellet shoots about 875 to 865 FPS. At 104 yards I'm at my 5th mil dot. I was shooting at an aluminum square sheet about 2 feet by 18 inches painted black so the pellet strikes are clearly visible. I then decided to try my hunters supply 49 grain bullet. The impact was almost identical. I don't know the BC of the bullet but never imagined it would be that close.

more likely its slower velocity and a much better bc, so at 100yds they work out the same, but if you go to 125 the pellet would be lower and the even though the bullet started out slower it would now be going faster and not have as much drop. Of course the only way to verify this would be to put out a chrono and risk hitting it. Im told there is a way to use math at different distances, and known speeds to figure out what the bc is if hunters supply doesn't publish the numbers.

Thanks Dan. I have accidentally shot my crony too many times up close to trust myself at 100 yards. lol

Chairgun Pro App has a coefficient tool that is very accurate if used correctly.
