The shorter stiffer barrel probably has a tendency to shoot better. Especially if shooting more than 10 shots per string, like when varmint hunting..
That makes a lot of sense. Also consider these barrel all free float and tinkering with bedding or pressure points is not an option. My gut feeling is same as yours. I really like that it is not a full blown gut busting 'varmint' barrel.
This seems like somebody gave the Predator a lot of thought. I feel the same way about the two standard offerings with lighter 18" or 22". Somebody or bodies got it right with the American.
There is a lot of years ahead for this. Maybe a nice wood stock. Or a 17 WSM. I never had a 17 anything. For 3000 fps, I might take the plunge. Not interested in a 77/17. I could almost splurge on a 77/22 if that gun got the American type trigger. As it is, not interested.
They still need to do a lefty for that neglected 5%.
