I have a Mossberg, bolt action, 410 I got as a young lad in 1965. I will not be using it for hunting. I have been thinking about cutting the barrel and stock down, but since it is bolt action don’t know is this is a good idea.
What do the experts here think?
A gun like that may be more valuable if left intact. I would just go buy a new pump shotgun with a pistol grip, and leave the old-timer as is.
A barrel can be no shorter than 18” (muzzle to closed breechface) and the overall length cannot be less than 36” without running afoul of the NFA (National Firearms Act of 1934). If you wish, cut the barrel to 20” and leave the stock alone.
Look into Winchester PDX .410 ammunition.
