You have touched on a subject that often gets overlooked when reloading for old English Double Rifles - BORE SIZE.

There is no doubt that there was some variation in bore size when they left the factory, but the ravages of time, corrosive primers etc, can result in even more variation.

Often, the rifling can look quite sharp owing to corrosion simply removing metal wholesale, not just showing up a pits, as is commonly assumed.

In .400 cal. I have seen bore diameters that run from .408" to .416", and there is no guarantee that both bores will be the same! One reason why some doubles just won't regulate (did you slug BOTH bores?).

Woodleigh make two bullet diameters for 450/400 to cover this (.408" and .411").

If you are looking for low cost "plinking" loads, have you thought of using .41 cal pistol bullets? Speer make 200&220 grain soft point (look a bit funny!), but I have got them shooting in a number of rifles, double and single.Point of impact is usually a bit high though.

With Cast Lead, you could start off simply with Wheel Weight alloy - usually works, although I have no personal experience with 450/400 to draw on.
