Thanks guys!
Rm100guy, Not really, just noticed it for the first time since I don't normally look at the gauge when shooting. When I saw it, it made me wonder if maybe the reg was having an issue. Glad to hear this is normal. Mine is also set to around 135/140b. I turned down my HS thinking I might get better accuracy and shot count. I was shooting around 934 fps with a SD of 2.23. But I think I was approaching transonic speeds at higher temperatures here in Texas. I started seeing a few random POI shifts. So I have slowed it down via the HS to around 895 fps but my SD has increased to 5.0. Not the end of the world, but I am trying to always improve and find a sweet spot. I am still testing with the POI shift vs temperature (100 degrees +).
Centercut,
I knew you had replaced your .30 with the huma, read a few of your posts. Guess your still a fan of the Huma? Do you know what your velocity and SD numbers are running? Sounds like your reg gauge is doing the same thing as mine, just at different values. Good to know. thanks for the input.
