Sorry to hear of your choice, my Faxon 16" barrel was terrible quality, torn and galled rifling, some of the first batch ...but most early ones were that way... a waste of time and components.
The 3 twist is very limiting, and unusable for lead supers. And adds no practical value, but detracts from the cartridges potential.
I purchased a 6.5 twist McGowen with varmint contour and chambered it for the Rem 700, and left it 24"
It will complete with the 338 Federal, with supers, and shoot subs in the form of 300 gr match bullets very accurately.
No downside, no worries about bullet blow up as with the 3 twist.
With the 6.5 twist and long barrel one can achieve over 3000 ft/lbs of muzzle energy for hunting with cheap lead bullets.
200 grs at 2612 fps, 225 grs at 2481, 160 gr Barnes at 2800 fps.
There are better choices than the Faxon 3 twist...been there.
