Contender 300 Whisper twist?

WarGames

What is the factory TC twist?

WarGames,

It's supposed to be 1:8" if I recall correctly. This is to stabilize the very heaviest 240 gr. Sierra Match Kings for subsonic velocities and the ability to suppress the sound.

Best.

ADDED:

I went back to check this against my notes and the older factory barrels do indeed have a 1:10" twist rate. But to handle all of the heaviest bullets, the 1:8" is required.

Best.

1 in 10 inch unless they changed it later Dave this is from sierra 50th anniversary ed midway has barrels for 300 whisper 1 in 10 twist Dave

All I can find is 1/10.
Doesn't make sense to me.

Looks like a custom barrel is needed for the correct twist.

The big complaint with the TC and 300 Whisper is the lack of a 1:8 twist barrel.

Like the others have said if you are wanting to shoot the 200gr + bullets you will need the 1:8. There are people that do load supersonic light bullets in their .300 Whisper but it makes no sense to me since it takes the Whisper out of it.

While the 240gr SMK's are a great bullet I am shooting the Hornady 220gr RN since they are just under 1/2 the price and I still get MOA accuracy out of them.

I know in AR barrels there are a few companies make 1:8 twist barrels. I had a custom barrel built for mine because I got exactly what I wanted.
