Yes,16 inch . I don’t know from personal experience, but I have a friend that used the Winchester factory loads to take 3 deer this year . He says it’s as good as his 300blk and perhaps a little better. I know that you can’t use the Winchester brass with .357 bullets in my ruger ranch rifle , the neck area of the chamber is to tight to chamber a round when using .357 bullets. The starline cases have thinner necks and work fine. I bought the rifle to shoot suppressed 180 grain Hornady XTP bullets , and that’s all I’ve shot in it to date.I’ve taken 2 coyotes at around 75 yards and several hogs at close range. It’s had enough power to drop them very close to where they were shot. If I wasn’t so heavily vested in 300blk Supplies I’d likely get deeper into the 350 legend .
