Concise and informative, thank you. Hearing that the correlations between wind deflection and velocity retention are linear is very helpful. I was surprised to hear that projectile weight has no bearing on BC calculations.
A real simple demonstration of BC is to take a sheet of A4 paper and try and throw it across a room . Se how accurately you can throw it and how consistently it travels in the air . Now take that sheet and crunch it up into a tight ball and throw that across the room . instantly you will see the difference . Both Projectiles are the same weight and the same material but the crunched up ball has the better aerodynamic shape and therefor the higher BC .
Mr Practical Tactical in one very short vid you have explained many hours of reading from books ( do u remember them ?) the concept of reloading for accuracy . Thanks very much . Cheers from New Zealand.
The number on the box is NOT marketing; the number correlates to the bullet profile under a controlled environment. When you're evaluating performance in real world settings, those values will obviously shift, but it's a reference point because you can account for different environmental conditions.

Very interesting... and easy to understand the somewhat confusing Science of Ballistic-Coefficient.
That was excellent, thank you.
Awesome video. Love this

Thank you Mark. I really appreciate the positive feedback.

Hi, what BC should one use for 1500 yards range, 7.62x39 mm, 123 gr, FMJ BT bullet?
sad to say 1500yds is a very tall order on a 7.62x39mm. Won't happen.
@@dimgl19can happen easy. Granted yes its a long shot for lil stubby.
@Daniel Nelson no, it can't "happen easy." Post a video showing you achieve it since it's "easy."
@@no-sway3709 Maximum range for flat base 7.62x39 bullet is over 2500 yards and BT over 3000 yards
@Ime Prezime max range for a point target or area target? And you said "easy" so post a video of it.
To much info. Looking for bc info only as your title indicates...
Are Canadians even allowed to say the word gun anymore?
Apparently after the liberals backed off on the hunting gun ban today, I think maybe we can.
Back in my day, Canada was the wilderness man’s dream. Now wow!

Sounds like you are new to long range "precision" shooting. Work on it for 40 years and get back to me.
This video is My last hope of understanding BC!!! If I don’t get it by the end of this video I’m giving up.
