In my 270 the jam point is .285" further out than factory ammo seating depth.
I gained nothing in accuracy by seating 140 AB's .015 - .020 off the lands and think like other posters have written that I should go to factory length as a start point.
From what I have read the bonded bullets are better with a .050 jump and the non bonded bullets .010 ish. Makes it confusing.
I have found AB's to be great bullets, always a pass through with a big glob of blood on the ground. The animals will often run a few metres with blood pouring out but I have never lost one. The AB's open fast and the wound looks like it's been cut with a hole saw.
There is a bloke on the forum @Pongo who probably shoots more deer than anyone here and he uses the 168 Berger in a 7mm Saum or WSM near and far.
