At risk of repeating myself or somebody else, I THINK an 8 twist would be adequate for a 90 gr Swift, surely for some of the 82 grain bullets coming out now. Berger recommends a 7 twist for their 90 grain bullets but that is in something like a .223. You might should actually talk to somebody at Berger to get the straight scoop.

Added barrel length will get you a little free velocity and move the muzzle blast that much farther from your ears. It will not affect the shooting otherwise. I have a couple of 28 inch barrels because the first was what Krieger had in stock and the second was the longest Pac Nor makes without charging extra per inch. No stronger reason. Palma shooters typically use 30 inch barrels on their overloaded .308s.

If you are going to stick to the factory Ruger stock a 26-28" medium heavy would be about right. I think the 77V Swift has a 26" barrel, the sporter 24"
