Anyone have one? UPS just delivered mine, it has the correct part # on the package but it looks like I could shoot a 12 gauge slug through it. The boss with the muzzle break I have, has a crown screwed on the end roughly the same diameter as the bore. Also the cr is about 3/4" longer. This is for a 300 win.

I'm puzzled. Did they ship the wrong size?

I have both the CR and the ported BOSS for my 300WSM. Yep, they look much different, the dia. of the bore in the CR is big, really big. I dial my ported BOSS in when doing load development and screw the CR on just before hunting. My setting are identical, YMMV however.

Thanks Steve, that makes me feel better. It looks so different I was afraid to shoot it.
