Accuracy testing was done prior to the arrival of the Magpul PRS using an A2 stock.
Five shot groups were fired from a bench at 100 yards using front and rear rests and a Leupold VARI-X III set at 25X.
The best groups were obtained using Sierra 77 grain MatchKings and VihtaVuori powders.

A ten shot string of this load chronographed at 2638 fps with a standard deviation of 10 fps.

Using VV N140 the best 5 shot group measured .394".
A ten shot string of this load chronographed at 2643 fps with a standard deviation of 12 fps.

Thankyou for doing 5 shot groups!!!!!  Its gets old watching people post about their 3 round group that had a flier.  


Whats the chance on posting a pic of the weapon as well?



ETA-  What make of barrel?

The barrel is a Krieger stainless steel DCM HBAR.   Please refer to my other post on this rifle.  Lot's of pics.  For some reason I couldn't get everything to work in one post.

It sounds like you might appreciate some pics of 10 shot groups from this rifle.  These were fired from 100 yards using handloaded Sierra 55 grain BlitzKings.  (I haven't had a chance to do 10 shot groups with the 77 grain MatchKings.)  The groups measured .793" and .747" and yes the measurements included the "flyers".

And 20 shot groups (one mag) is what is king.

I did forget to add though. I'm not crapping in your thread. Excellent groups. Nice shooting.
