Mike Wilson has just shot a potential World Record Light gun group and score. With a 1.068" 50 score with 5 X's. Congratulations to one heck of a good guy. It is well deserved.

Caliber is rumored to be a 6BRA which is a 6mmBR-Norma blown out to Ackley Improved with a 35-40 degree shoulder and less taper for more powder.  If I find out more, I'll post.  This is amazing.  He held .1 for 5 shots at 1k.  Taking into account all the variables, it's hella good shooting. 

Yes, I realize that this is a very specialized rifle with a 20 pound front rest and such, but it's still amazing.   I've seen wind blow 3 different directions over 600 yards so over 1k it's probably going 5-6 different directions on the bullets course.  Spin, drop, wind...  crazy.

That's insane accuracy.

Yes.  It really is.

That grouping took a lot of skill and concentration to produce, but I have to say, I think a little bit of good luck was involved too.  Like you said, a lot happens between the muzzle and the target out there 1000 yards away.

It takes skill to eliminate everything except luck.

Luck favors the prepared.  And the prep on the loading front alone is enough that I wouldn't/couldn't get near that.  I understand how meticulous these guys are.  And why.  

I think it's amazing.
