I like .015" with many bullet types, but I've gone as far as .025". Much beyond that and you may start pushing the bullet back into the case.
That said, some reloaders deliberately seat very long,+.035), and let the lands seat the bullet. The concept is that this will provide the most consistent seating depth.
I don't want to suggest this is a definitive answer, but there's no reason not to try +.020 as it may work a little better. Be aware that, as you approach a hard jam, your start pressures can increase, so back off your load a bit first.
