well, so what if gun is out of proof...unless you plan to export it from the good old usa back to england...
what is more important, are the barrel wall thicknesses, particularily in front of the chambers...
and of course the ammo you plan to shoot...
but then, if you dont mind being ripped off by the purveyors of 2 1/2" shells or making your own reloads, then go ahead and pursue these more costly alternatives...
as for value of altered guns, some collectors may want guns to be as original as possible...
and some shooters like guns with chambers safely altered to shoot a variety of readily available ammo...
like some other questions, there is no one answer to this one...
