A6E,
Thanks for the info on that other article. I happen to own a 1517 MPR and am not surprised by the reported accuracy. I have shot a 50 yd 3 shot group in the .10's (my best to date) and average in the .30's. I am going to have to clear some more brush out of the backyard to extend my range to 100 yds.
An interesting note on the original article you inquired about. That 0.8 in avg was shot with a 6 power scope. I wonder how much better it would have been if he stepped up the power a bit.
