Rob, If the rifle is crossing the speed is too low! The bullets are staying in the barrels too long. You didn't say if this rifle is a S/S, or O/U, but both will cross if the speed is too low.

D1,
Sorry but I don't agree with that.
If the velocity is too low and the bullets stay in the barrel too long imo this will (usually!) cause the barrels to shoot APART not crossed.


Rob, drop the load and velocity a tad and try again and yes, do try the rifle with scope removed using the irons.

I should add that not all doubles do the same things when changes to the loads are made.
I have worked with a couple of doubles where even a minor change in the load can send the barrel groups in ANY direction!
That said I have a double here that will handle major load changes with little effect on point of impact or grouping.
