Creedmoor shooter

Ok so I tried tweaking my load alittle tonight. I shot 42.1 and 42.2 grains. 42.1 opened up to .6 and 42.2 went to .9. So I'm going to try going the other way and go to 41.9 and 41.8 and see what happens.
View attachment 93446 View attachment 93447 Just a thought but I would be more worried about your es if you're wanting to adjust your load than going from .5 to .3moa.
Sometimes it's easier to get a better feel for how a rifle is shooting farther away once you're really tuned up.
I attached pics. At 100 it's hard to see what's going on, but rifles with a decent load shoot in a circle. Shoot 10 on a perfect day and exclude the outliers, examining the circle of bullet marks. A nice round circle indicates what a rifle is actually shooting in terms of Moa. The red plate is at 550 with my 130eldm. The 143eldx shoot darn near half that size out of the same rifle
I generally clean around 100 rounds or so.What is the cleaning cycle on this rifle? Do you clean it after every group?
If you have a bore scope, After the 4th shot check the bore it may be a problem with buildup somewhere in the barrel. Causing the 5th shot to go Oh S!!!
With a custom barrel this should not be a problem, But I have had to do a lot of lapping on factory barrels to get a rifle to shoot a consistent groups after about 3 shots they would start opening up and every shot opening the group bigger.
Just something to look at in your quest for consistent little group.
Now that you mention it they're generally low rightIs the flyer always low like that? In the first group you posted the flyer was low too....
I guess that could be possibly. But consistently the 4th and 5th shot?Maybe your getting a slow round every now and then? Ignition problem?
