Twist for 7mm for 1,000 yard F-class ?

[Hammer]

Having a thousand yard F-class rifle built.

Using a 284 Winchester case.

Will a 33-inch barrel with a 9-inch twist suffice in keeping the VLD Bergers stable out to a thousand yards ?

A barrel finished 32" is common in F-Class. A 9" twist is more than enough for 180 VLD Bergers and adequate for 180 Hybrids.

I'm not sure that many are more qualified to answer your question than Steve. And I'm fairly confident those that may will answer the question similarly.

With that barrel length and and twist rate you should be able to stabilize 180 VLDs out to 1k easily.

You didn't specify what grain bullet so I'm assuming you're referring to 180 VLDs. However, most are shooting the 180 Hybrids.

In my opinion skip the 33". 30 " is plenty and anything from a 8.5 to 9 twist will work great.

9 twist is what I use in a 32" barrel with 180 Hybrids.

Haha. So speaking of...these guys are literally the top in the sport.
