@@heinzlive I know, but perhaps somebody else with the right equipment and range can pick this up. Some longer distance tests have been done by user 'Yrrah' on one of the US forums I believe, but it's been a while.
@@mus1970 This was studied by Dr. Mann in the early 1900s and discussed in his book A Bullet's Flight. A pdf copy is here: duienforcers.wildapricot.org/Resources/Documents/BulletsFlightPowderTarget_Mann_MunnCo_1909.pdf Tests by famed barrel maker Harry M. Pope were also performed and agreed with Dr. Mann's results. In short deformations on the tail end of the bullet tend to cause greater error because of the asymmetric pressure load on the base of the bullet when it exits the muzzle. Deformations on the bullet's nose tend to cause smaller deviations - at least in the supersonic conditions that were tested. Dr. Mann also found that gyrations caused by imbalance of the bullet's mass about the spinning axis will also cause deviation and is quantified to some degree in his book.
@@ardentlieutenant3390 hello, yes you right... that's a strong point... but even so I would never shoot such pellets in my pistol. Don't you think that they could ruin the "rifling"? Would you use them?
@@NicolAeBartolomeo I think when shooting I am concentrating on other things so would likely miss them anyway. I note the author was happy to shoot them through the barrel of an expensive rifle.
@@ardentlieutenant3390 hello, your name make me guess you are from Ardennes... am I right? If so I would be in Marche en famenne for the BOA... if you will be there we could meet if you like.
Great work. Thank you.
Sir Please make a video on 10m Air rifle peep sight adjustments
Check my channel, you will find…
Interesting test. So for 10 meter shooting, it hardly matters. But what about (H)FT distances, or 50 meter benchrest?
…not my field of play

@@DavidBeerer Thank you very much for the link to the PDF! I'll be reading the book with great interest.
@@mus1970 hello, I'm interested in the argument and I ask myself if you still have that pdf link... thanks and happy shooting
Such pellets could even ruin your gun barrel... isn't that?
Lead is soft and the barrel hard.
