I posted a little link to a printable 8X10 version of a B8 in my original post.
B8 is an NRA 25 yard timed and rapid fire pistol target.
Generally, if you can keep them all in the black of a B8 at 25 yards consistently, you have my attention as a shooter. It looks much easier to shoot than it is. Not only do you have to group well, but you actually have to hit what you are aiming at.
There is no time limit, so take your time. If the shot doesn't feel right don't take it. I tend to time my 25 yard groups from the draw, but that's just because I want to add a little pressure. I usually end up in the 35 second range to shoot a B8 at 25 yards. Remember at this distance sight alignment and trigger press are more important than sight picture. Don't get sucked into the "Now!" syndrome.
