Yes, as long as you use data from a load recipe calling for the type of bullet you have, they are fine.
.001" of an inch makes absolutely no difference in pressure or safety, one way or the other with normal loads.
We commonly bounce around with the .45 Colt with bullets ranging from .451" up to .454" using the same powder charge. It all depends on which size best fits the cylinder throats.
To give another example, look at a .30 cal rifle.
The hole through the barrel is .300" with .004" deep rifling grooves. But you use .308" bullets.
SO, the bullet is actually .008" bigger then the the lands, and approximately 1/2 of it must be squeezed down .008" when it hits the rifling.
As you can see, .001" difference in a .45 bullet isn't very much in the grand scheme of things.
