Thread: 308 twist rate

I saw those videos regarding the q rifle and the 8.6 creedmoor ( more or less a 338 whisper or br which out the trade name ).
Ask @Wingman what was the twist rate of his 338br and what projectiles he was shooting subsonic and how they where flying.
For the majority of what we are doing , I don't think that super fast twist are of any use.
Overstabilising at a rate of 1 in 5 twist might cause some failures in conventional cup and cord projectiles specially if flying at supersonic speed.

When I started f class shooting in early 2000, I remember very well the competitors having the old 7mm a-max exploding in mid air when launched from a 1 in 8 twist with a fast 284 win or a magnum. Not all of them but 1 or 2 out of a series of 12 or 15 was enough to make it to the bottom of the scoring board.

The 6mm ppc and 30 br and their wildcat cousins still win matches with 1 in 14 and 1 in 17 twist respectively.

Why is the venerable 22 lr still flying so well in 1 in 16" twist?
