A recent thread about a J-frame revolver showed some 38 Special loads with the hollow base wadcutter bullets seated backwards. I did this decades ago a few times for shooting out of my Blackhawk and just loaded them with the same data backwards as forwards. I am sometimes surprised I survived my early teens considering some of the things I did reloading. Should the charge be reduced due to the volume available for powder being smaller with the bullet seated backwards? I can see using the same charge of powder for double end wadcutters and hollow base wadcutters of the same weight seated hollow base first since the volume should be the same, but the hollow base bullets seated backwards should have much less volume for powder. I would think that could produce pressure problems.
