Shouldn't a lower bc cause the bullet to drop more?. If a 6.5 creedmore has a bc over .5 it is much more efficient than a .243 win that is going faster at the muzzle but has a lower bc of some where in the low .4's depending on the bullet of course. That's why a 6.5 creedmore stays super sonic longer and is more effective at longer ranges.
Its a factor of both - MV is easy to measure, BC requires either Truing or specialist equipment to get the actual figures - in the video we are talking about truing it at a certain range
Great vid that will help a lot of people,
Thanks. I just bought the PARD DS35-70LRF - 850NM scope this evening so will be trying this out soon but with .25 pellets instead.
Same process
Ideally with chrono and tune with BC
I will do my large long range chrono at bit later
Takes a while to setup
what did you end up adjusting the BC to ?
Really only valid for our rifle and setup - velocity, twist etc all have effects
