Unfortunately, aligning different bores is very difficult. Putting them in the same chunk of steel prevents them from diverging over time, at least, but doesn't solve the original issue.

They'll diverge as the gun heats up and the inner bores stay hotter than the outer ones. Both short term as you use the gun and the barrel warms up, and long term, when the bores wear differently for the same reason.

Good point! Hadn't thought about the bore wear - if they don't force successive shots to cycle through the barrels, that would be a huge issue.
