Brass shell length

That's about like shooting a .22 Short in a Long Rifle chamber.
If there is no taper into a forcing come, I can't see there would be any difference regardless of hull length.

I've wondered about that also, and my concern would be gas leakage in the 1/4 inch area of the chamber wondering about whether, or not, the wads would be able to make a seal in that area.
