Am I correct that a 900 can be shot with any caliber gun?
For example I have seen an announcement of a revolver competition that
will include a 900 and also a Distinguished Revolver stage.
Can I shoot a DR gun (i.e. .38) in the 900? I reviewed the NRA rulebook
and do not see any restriction as far as caliber for a 900 but thought
I'd confirm.
Thank you.
