I've got a 40x in 220 Swift. The chamber is throated so long that Berger and Sierra bullets are seated in the case less than .100" when touching the lands. I've measured with the Stony Point tool and the bullet slip method.
I have several loads that shoot consistently in the 3's and 4's @ 100yds.
These loads are jumping .090 - .100".
Is there a 55g bullet that would have such an ogive that the jump would be greatly reduced if they were seated just .200" in the case?
I would love to see how this gun shoots with bullets just touching the lands but that would probably require an 80 or 90g bullet and with the 14" twist I doubt they would shoot.......
