Went out today to shoot the Optima with the new glass. Had no luck at all! It was 90* in the shade and after a few shots, i decided to see how long it took for the barrel to cool down enough to where it was barely warm.... 23 minutes. Took my final shot and said screw this, i'll come back out this LATE evening when its somewhat cooler. The ways its been, i'll soon be setting up a flash light near my target and shoot around midnight when its in the low 70's .

You can barely see the fine cross hairs due to me resizing the picture, but i really liked the fine cross hairs today as it does not cover the 1" orange dot.
Optima in the shade cooling down,
I found that it really makes for a solid rest when i put my 4lb sock/bean bag under the rear of the stock.
