Both rifles are chambered for 105 gr class bullet.
I'm shooting the 80's in my Factory Savage F-Class 6MM BR rifle.
The 90's in my Custom 6MM BRA Kreiger barrel Fire Forming the Brass.

Amazing how well the 90's shoot fire forming. My initial test @ 100 yds ,2 shots into the same hole.
This was with the bullets .009 ITL's. Since the initial load / seating test. I have shot 1 "UBR 243 Target" at 100 yds. shooting in 6-10 MPH winds. I was able to shoot a Score of 60 w/4X's. This is just a Local club shooting centerfires for some bragging rights.

Just ran 3 powders through GRT.
SWP, N140, IMR4166

BC, Curious as to what the data was on the SWP. Would you care to share? I have a lot of it ( SWP ). I don’t have a computer just IPad and IPhone or I would do it.

Nice Grp. Curious, Do you know how far off the lands / in the lands your bullet is?

 

[Bc'z]

Touch was 1st 2 shots .003 off for everything else.
I'll fine tune seating after I evaluate neck tension and charge, but for now I know it's shooting well enough to read what it's printing on paper.

No velocity report yet, let me address neck tension and charge 1st.

Now where's the fun in that??
I'm doing bushing test next, I wanna know if it's gonna like more tension before I stand on it.
If it looks good tomorrow I might just shoot it Saturday club match.

Fir pure accuracy, none of the 80 or 90 grain bullets will stand with the Barts 80 grn Dominator. It’s a true custom Benchrest Bullet.

In my 6BRA, which has a .103 Freebore, I shoot the Barts 80 at 3450 fps with 33.7 grains of H4895, with great accuracy at 200 yards. I also have a load of 32.3 grains of N135 that shoots quite well. I shoot 1-12 twist Bartlien or Krieger barrels.

I am jumping them just a little, probably .010.

Looks club match ready…

Put an aluminum collar around it..w/ o-ring on each side to hold collar in place….

This was this morning. 20” 10 twist Remington Varmint on my little hunting rifle with my new 2-16 z8i.

Dominators and N135. I found my seating depth between .004 and .008 off but it shot well to .012 off (wheeler method.) I’m using 205Ms. It’s averaged .270 for 5 shot groups for quite a while. Coyotes hate it.

Sorry about the bad pics. There’s water in my camera.

Is the Bart's 80 grain Dominator a boattail or a flat base bullet?
