Boy, am I late to this party! hehe, better late than not at all. Yep, I have one on a Remy 700, Shilen 26" barrel, and is a switch barrel to a 358 STA. Right now I'm changing scopes and am having an adapter made so I can use my suppressor on it. (Somehow the brake has a strange threading.)
I will say that so far my rifle enjoys the 150 Swift Sciroccos. I was shooting 140 Acubonds and thought if you hit a deer with it, it was naturally going to run off a 100 yards and die. Kinda like my other deer rifles did.That was til I started using the Sciroccos. No matter how far, it either dropped them where they stood or flipped them to DRT. Could not believe the difference. I also haven't put the throttle to it, only running 3174 fps. But the deer are still DRT ! As soon as I can get the adapter I will make a run to the range and let you know what happens.
BTW, the 358 STA is great moose medicine!
