Seating Depth and Tuning 6BR

[Link]

I'm not sure of what to think. 6br 1-8 / 100 rounds on barrel. Varget 29.7gr br4s -+108 bergers - This load shot a .118'' at 100 = 2.758''
200 yards - NO WIND not a breath of a breeze 80 degrees\

light touch is 2.753 - just a hint of a mark.

Top left 2.755
m 2.758
bottom left 2.761

Top right 2.764
m 2.767
Bottom - 6 shots 30br 35gr h4198 BiB 112s 6shots

Try touch and work back .003

How many flags did you have out?

 

[Jud96]

You have to have flags to shoot small. Having said that, do as @L.Sherm recommended. You may also have to adjust your powder charge

 

[L.Sherm]

I would also test at your max distance you plan to shoot

3 flags all were dead, no movement. I couldn't believe it.

I would test from touch to .030 jump in .005 increments, if you can get them to respond switch to varget.

The reason I wanted to start at touch and inti jam is because of Barts video where he goes into jam. That might not work in my new barrel.

Those are a VLD design if I’m not mistaken, where the Berger 108 is a tangent ogive.
From experience shooting the 108’s most have like a bit of a jump.

shooting 108s.

Just a thought. I do not have experience with that barrel.
I find neck tension is a critical thing. Too much and my groups widen. I shoot hot loads also.

TG ejector? Are you measuring pulling the firing pin with Alex Wheelers method ?

 

[BuffaloBill]

I had troubles getting a build I did a couple years ago to shoot small. I finally took off my GE and put a different scope on it, and suspiciously shot a one-hole group. Vortex could find nothing wrong with the GE. I have it still and plan to give it another try, but my confidence in it has been shaken.

Just to rule it out, you may want to try a different scope, etc.

Shooting over flags is a necessity and having said that not a single person that has shot over flags KNOWS flags will lie to you at any time!

Every time I read a post like this where seating starts at touch and backs into jumping I shake my head and laugh. It's like buying a pie, cutting it in half and throwing half away and only eating half.

I guess I got caught up in Barts video where he said he always jams. I have some rounds loaded starting at touch and going into jump. I also have some VLDs loaded to try - when the weather clears ;{

could you please explain this ?

Not speaking for another man but I believe Jeff is suggesting starting at a jam and work out.
Example would be .030 jam to .030 jump.
