OK. I pulled a bullet from a PPU Factory Load and reseated it to 3.06"
Works as it should.
Barnes bullet at 3.06" hits obstruction.
It seems in this rifle (1903 Take Down) the difference between 3.060" and 2.960" is critical.
In the 1903 Stutzen the factory loads at 2.960" OAL feed perfectly.
Unless I can find a .264" round nose mono metal California is out of the picture.
Thanks all, for the help.
