The SPS tactical is a great little rifle and is capable of good accuracy It's two biggest faults are the wimpy Hogue stock and the crappy trigger.
With very careful stock placement on the rest and good handloads I was able to get results like these with a out of the box rifle.
I have since replaced the stock with a B&C tactical stock and a Timney trigger. The groups are getting smaller solid in the mid .3s this may be all that the rifle is capable of without some metal work or better higher power glass.
