Thread: 22-250 twist rate

Back in the day tracer was brilliant at showing up stabilsation issues. I loaded some tracer projos out of SS109 rounds, and reloaded them into my .222.

They would arc gracefully away about 200-250 m away, and then begin scribing a massive corkscrew pattern about 50m in diameter, all the way out to tracer burnout. Almost looked like a guided missile.

Most likely cause was the tracer not the rifle. Tracer is long for weight due to the compound being lighter than lead this can lead to marginal stability which only gets worse as the bullet slows. As it burns the centre of gravity changes and a real wobble sets in, quite spectacular to watch really
