Krieger barrels have a little bit smaller bore and cut rifled.
They're hand lapped also.
It's a fast barrel.
I'm going to try some XBR8208 next.
I turn the necks on my brass to .013 thick to use more powder with the tight chamber to reduce pressure and get more consistent neck tension.
I've been impressed with the barrels accuracy.
It shoots bugholes when I do my part right.
My 65grendel barrel hangs right with it after using the tubb's final finish kit on it.
Tried XBR with the 95 tmks and got same velocity.
Very good accuracy.
Tried them with 2000-mr and hit 2980 fps with good accuracy.
Got over 3000 fps but accuracy started getting worse and pressure was more than wanted.
Best accuracy came at 28.5 with XBR and 32.5 with 2000-mr.
They seem to be easy to get a good load with any usable powder.
I got 108 ELD's up to 2820 fps with good accuracy and low ES using 2000-mr in hornady brass but it's softer than Lapua and doesn't look to hold primer pockets for long.
