I only made it out for the Garand match this month, a cold kept me home from the Service Rifle match. It was beautiful, sunny and in the mid 60’s for the first relay. The fall sun made for some challenging conditions. There was an significant glare off my rifle, it was a challenge to keep on target. There was a an abnormal amount of smoke on the range as well.
Factoring the conditions I was happy with my performance, I dropped a 5 in rapid prone and a miss in off hand but I went home satisfied.
As far as the conditions go, I my opinion it’s just part of the game, sometimes it rains, sometimes it’s hot, cold, sunny, dark. I think these conditions underscore the need for a good natural point of aim. With a good NPOA it’s easier to keep rounds on target even if seeing the target is a challenging.
