If talking about shooting fast and accurately, especially from harder surfaces also?
Why do IPSC rifle shooters in the Standard class shoot from a magazine rest vs. mag off the ground?
Gives to a much more stable platform and less recoil.
But what do I know, I am an Open class shooter with bipod..
( Been on the National IPSC Open rifle team though almost every season since 2009 and seen plenty of Standard shooters also )
