Does the OAL have an impact on accuracy like a rifle? Anyone have any experience with this?

I happen to have an Oregon Trail reloading manual[no longer available] and their OAL for this bullet regardless of the powders they used was 1.250! As you're probably aware the OAL can have a significant affect on the resulting load pressure of a cartridge.
I suppose it could have some affect but I doubt that its anything like it can have in a rifle. I don't think pistols are made that have extended throats like some rifles and the amount of bullet jump affects accuracy.
Just my $0.02!
