I have a 350mm 30cal with a valkyrie kit. I also have a Donny fl installed in some photo's as well. I haven't shot for groups as of yet but when the weather gets better I will.
@RonT
I haven't got out to shoot at all weather is bad in the east right now but yes I see other guys posting groups I can't wait to get out and see. I have my limited addition Delta wolf on order as well but looks like will be waiting a while before it's out.
@sonny it fits back into the factory box same size as the factory 350mm I just remove the moderator is all. Actual measurements I haven't done but it's the same I would say because it fits perfectly back in the box.
