Airgun shooting in strong gusting winds at 425 yards using ATP Super King slugs RU-vid Audio Library : Echinoderm Regeneration by Jingle Punks from RU-vid Audio Library Pentagram by Audionautix
twist 1:12 is enough to stabilize them, but it makes the BC a little worse (barrel 1:12 is just used in the video) A twist of 1:10 would be fully optimal
Thank you, energy of 143J (.22) can be achieved with a 755mm barrel, which is a speed of around 256 m/s with these 67gr. Airgun with higher pressure can also achieve higher velocities that this.
