Tell me if my Chrono is off
Temp: 75

Starting to show slight signs of OP, any one shooting that type of speed/w 44grns of Varget. Everything seems consistent, but speed seems alittle to high, but it shoots fantastic. Just wondering if my chrono is TU, going to try and get out to shoot 500yds on Wed/Thur and do some
actual shooting to test my drops.

I can't say at 44.0gr, but at 44.5gr this is what I was getting:

Lapua brass - 3747 fps
Win Brass - 3671 fps

My elevation here is about 900 and the temp during my testing was 75 F (pretty similar to yours). If you're getting 3825 with 44gr, congrats. But is does seem a tad high.

I must say though that yesterday while groundhog hunting a lot of my shots were going high. Maybe yours is right and I need to check mine now
