In my opinion a 1 in 8 or 1 in 9 would be better.
The really fast twist barrels are hard on bullets (They have to start very fast and can engrave
poorly). if you want to end up with a very fast twist rate you might look into a gain twist barrel.
For accuracy most bench rest shooters go with a slower twist to get cleaner engraving of the bullet.
If you were shooting something very slow like a subsonic the 1 in 7 would work.
Most of the 223 rem shooters tried the 1 in 7 and even the 1 in 6 and went back to 1 in 8 for the best accuracy.
Just my opinion
