Tonight was our second annual night match.Last year i thought the lesson was to use a light with more lumen among other things,which i did but now i'm not sure.My set up this year was a jp 18" W/cooley comp and a surefire M4 devastator W/the 350 lumen lamp in place at a 2 o'clock position,and for optics a TA31.The weather was raining and around 40 degrees.The problem was it was like shooting black powder where you cant see the target right after a shot because of the smoke.After each shot your scope would white out as best i can describe for a moment making you blind untill the flash,steam,smoke,or what ever would drift away,even though we are talking micro seconds it would distort ,confuse,and lose your sight picture/nexttarget ,besides making you blind especially on the shorter stages with multible closer together targets.It was horrible.whats the lesson this time?Different optics,no magnification, less lumens,or a flash hider instead of a comp.One thing is for sure,i would never want to engage multible threats coming in fast with what i used tonight when its wet cold and dark.Whats the deal?
