From their chart, it's a 1 in 11" twist.
May like 175gr bullets better, but should still be good with the 165gr weight.
Interesting, had not considered the twist rate...

Getting a chronograph would probobly be the biggest difference maker to advance yourself.
Updated my post, #18, with some load data for you.
There’s one at the range, I was wondering if knowing the velocity will help with accuracy? Or am I looking for consistency?
If your brass is old it may need to be annealed . I've found old / mismatched brass makes more diff than I thought , I weigh my brass and group from light to heavy in the box
https://www.dropbox.com/s/m9ovokvfb6n8uys/cgnpic.jpg?dl=0You are looking for consistency. Low extreme spread and standard deviation numbers. You might have a load that looks great at 100 yards. But high numbers will make that load ugly at longer distance.
Also highly doubt you are having low pressure issues at around 43-44 grains Varget. Take pics if you can of the fired cases.
Ok, I was wondering what could cause the case to not seal in the chamber. Thankswith no spaces or " gives you:![]()

Looks like Dropbox doesn't like to link directly.
Do look under powered with all that soot on the necks. Brass not expanding to seal chamber.
I do take a min in between groups, but obviously not nearly what ur suggesting. It’s def no bull barrel, But if you do some reading on Sauer rifles, the German quality in barrels are working better than average after heating up. Don’t go off my results. They come with a sub moa 5 group guarantee from factory , taken with grain of salt, but I’m gonna stick with my 5 shot groups for now. I have considered barrels temp. All groups were .5 gr difference. I’m confident in the set up, this was literally only day one, thanks for the tipsYou have a hunting rifle with a noodle barrel lol. The first 2 or 3 shots are going to be the best in terms of accuracy and precision. I wouldn't stress about anything around 1.5" groups because that's probably the best you are going to get. My barrel is 1" in diameter and I can shoot quite a few rounds and shoot 5 round groups for load development with no change of point of impact on the target from the barrel heating up, where as you can probably shoot 2-3 before bullets start getting slung out like they are coming out of a 12 gauge shotgun. Just something to think about.
If I were to do load development with that rifle, I would be shooting 3 shot groups at .5gr difference, from an absolutely cold bore. Meaning its going to take a day to do a proper load development unless you are cooling it down in an air conditioned vehicle or something between groups. Varget, lighter bullets, and consistent brass is the best chance you have with that setup. I have found nodes in the 43-46gr range with varget in my 308's, but be aware Varget differs greatly from lot to lot, by as much as 150fps which translated to over 1.5gr difference in charge weight for my rifle. Wipe your chamber clean, monitor pressure signs, and try to get up around 44gr. And...… get a better scope.
