Can I get SAUM help

Twist rate of barrel? How is your bullet stability? I doubt it’d have that big of effect unless the bullet upsets.

Whats your ES look like with respect to velocity?

10 shot string es was 26 fps

It’s a 1-8 twist

The only thing that is new to me is the xlr chassis it’s my first chassis and I’m not completely sold on it yet. maybe it’s screwing with me and parallax??

Rules that out.

I’m thinking I hit a false node or maybe the parallax on the scope it’s messed up

What was the velocity on the fliers? I have started using the garmin on every shot, and helps rule in or out at least one variable.

Also are the fliers random in the string? Or a hot barrel always?

Just built this 7 saum on a tikka action 20” proof I have several two loads I developed 165 gamechargers and 162 eldm at velocities around 2790s that shoot bugholes at 100 yards but I cannot get it to group @600 and out on several range trips and I know it’s not me I shoot a lot out to 800yrds. Any ideas where to start? already checked torque on scope and action screws. I have about 200 rounds on the barrel

What tikka did you use? I’m curious I have a 6.5 PRC tikka and was wondering how that would do?

Did you do your load development at 100m/yd? I find it's valuable to test my loads at 3-400m. That's the real truth teller. I dont think there's much value at doing your ladders at 100 unless you're in a hurry. Also, I've found that some loads don't look great at 100 but are super tight around 4 and the other way around. 100m is a liar sometimes
