That is asking a lot from a lite contour barrel. I shot 10-15 shots out of my CTR 260 barrel in local club matches in under 2 minutes and it was under 1 moa. I have a lite contour from McGowen in 6 Creed for coyote calling. Very accurate, but the most I have shot on one stand is 3-5 shots in 2-5...
I will second this on the Berings being good in high humidity. I hunted a few weeks ago in 90% humidity and frost forming on the gun, call, and tripod. Didn't not any difference in visibility at all.
I bought a Hogster 35 for a scanner and a Super Yoter for my main scope last year. I picked up a $16 selfie stick with an internal battery off of Amazon, tapped a cheap piece of pic rail, and use the 35 on it. You won't have to worry about battery life.
I have put the 35 on an AR and my son...
