I have the STR desert tactical in .300 win mag with an IOR crusader scope to help with the long shots. Great rifle at a sensible price that weighs a tonne, but that helps to give it rimfire recoil. The bolt was a bit rough at new, but I gave it a good oil and after some use it is now nice and smooth, the trigger was superb for me out of the box, and the old addage of if it works don't fix it comes to mind.
