Last weekend I popped out and zerod my 308 with its new scope. Over the chrono a 5 shot string averaged 2750 fps there was a 40fps spread over the 5 shots lowest 2725, 2734, 2752,2763, highest 2765. That was a 150 gameking with 45 grns varget. I also tried 45.5 and 46grn loads. Now the 45.5 shot under an inch group so I decided to run my last 2 over the chrono. Now I know 2 shots will not give an average but I was surprised when the 1st was 2750 and the other 2711. What do you believe could be the cause of the poor speed load??
Now before I get lynched asking about speed Ive Swaro Z3 with a brx reticle. So I believe an acurate average is well worth knowing..
