Stay away from the fast twist stuff. If you are varminting, that is what the round was developed for and have fun with it. I would suggest that you look at the Vmax 50 grain bullet. It too will shoot very well and out of a 26 inch barrel, it will be a Laser.
I don't own a Swift but if I were to get one I'd do exactly this^^^^^^^
Long Barrel.....12/14 twist....50/52gr bullets....
