It may depend on how tight the throat is. On my 223, 6.5x284 , 308 and 8x57 the bullet seems to hang up in the throat and not on the rifling. I get a shiny ring all the way around the cartridge.
I know that an oversize (on diameter) throat is a killer with boat tail bullets and since all the above are set up for high BC bullets perhaps it is just "tight" in the throat ? All are new and possibly it will loosen up as the round count goes up.
I for sure will extract the bullet from the cartridge with as little as 0.004" jam in any of the above.
