This brings up an interesting point ...
A bill has been in the Maryland legislature for some time, requiring ammo microstamping. Many moons ago I trudged over to my state senator to talk about some of the issues that I had with the bill. Full disclosure - he supports the bill - I do not.
1. I asked why this bill when the law on the books in Maryland for 5 years/more or less, requires all gun purchases to have two spent shell casings from the weapon be sent to the Maryland State Police. Maryland's finest somehow created a database somewhat akin to a fingerprint information base about all sold weapons and their case marking. During this entire time that the law has been in force, the police have never even found one match from a crime scene. Nada. His reply was, along the lines of "well maybe this bill will improve that situation".
2. At the time, the tax was to be 50 cents for each cartridge sold, be it .22 or .50 cal, since then the bill has been reduced to 5 cents per cartridge. Did I do some good in complaining?
3. Reloading. Well, my friend, Democratic Republic of Maryland will treat you as a manufacturer. Get your microstamps on the casing as well as on the bullet. It would indeed be illegal in Maryland to reload a shell casing that had a microstamp.
I tried to argue but his comments we somewhat on the lines of "...some broken eggs to make an omlett".
3. What are about the tens of thousand rounds of ammo I now have? Reply was "the law will give you one year to use any ammo you have "stockpiled" and after that one year it will be illegal to own and you must properly dispose of it. He chided me for having such a large amount of ammo in my possession, albeit it was not against any law or regulation to own that amount.
4. The current bill requires that all handgun ammo be microstamped. Would that include .22 short, asked I? Emphatic yes. Resounding yes.
5. The current draft bill specificially excludes ammo for the M1 Garand. Does that really mean all 30.06 is excluded from microstamping or just those rounds you shoot from a Garand. How about some of the .308 Garands that have been manufactured/sold by CMP? The meeting ended at about that point.
I came away with the thoughts that they are after my guns. They want to take them away, all of them, and "they" will do just about anything to take them away or at a minimum make them unusable.
