    Second time around as good as first

    This is my second one of these. The fact that I repeated should speak for itself. Shoots high speed ammo and ultra high speed flawlessly from the get go. With federal high speed match got 10rd 3/4" group at 50yds first try out of box. With SK match got 10 rd 1/2" group at 50yds on first try. With subsonic SK had to reach up and gently"bump" the bolt with my finger to finish reloading cycle but after figuring that out had no problems. I'm as pleased with this one as much as my last one. Practice, practice, practice.
