Captive piston ammunition under HPA

Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

Captive piston ammunition under HPA

Post by gixxerpilot750 »

From what I've seen to date the reason people don't generally experiment with or shoot captive piston ammunition in the USA currently is each round must transfer as an NFA device. If the HPA goes through in the first 50 days of the new presidency as has been suggested, I would think that a person would be able to load this type of ammunition. The brief amount of reading I've done has suggested that all of the russian captive piston rounds used steel cases. Is this because it's russian ammo or because it's a design requirement? I'm trying to determine what in terms of equipment and supplies would be required for an individual to load this type of ammunition after the HPA has passed on the premise that doing so will be legal for the individual. If each round is registered as a firearm rather than an NFA device my understanding is that an individual could manufacture their own captive piston ammunition as long as they are not selling or otherwise transferring it to others.

I would think all that would be required would be more or less standardized chambers/reamers, the heavier walled possibly steel cased cartridge cases, loading/case forming dies, and the pistons themselves.

Does this all sounds right?

Thanks and happy holidays

Sounds reasonable, not legal advice.

Also sounds unlikely, devices removed from NFA will likely be specifically named if removed at all.

You may still need a captive piston weapon to take full advantage of captive piston ammo.

My understanding is that the firearm is not the restricted part of this equation, the ammunition is. In Paulson's Silencer History & Performance Vol 1 Arms Tech's 6mm Hazmat is mentioned on page 63. The same cartridge and the two barrel derringer type pistol chambered for it is pictured on pg 65 of Vol 2. The American Derringer Corp DA38 seems to have been the host firearm for the 6mm Hazmat. The Russian S4M or MSP (not sure which is the correct name, it's listed as both in the link below) looks really similar to a DoubleTap Defense two shot pistol, and given the fact the Doubletap has been chambered in 7.62x39 and 223, I'm sure it wouldn't be a stretch to have another set of barrels made. Otherwise take a look at American Derringer Corp's LM4, it looks almost identical to the SM4.

(Mods, if linking to another site is frowned upon please feel free to remove the link, my only intention was to include it so that people could see what makes up these rounds to be able to further discourse) Some cutaways of the various rounds can be viewed on this thread:

Nothing in my response said the weapon was restricted.

discuss? not discourse? potato ... potahto maybe ...

your post is not unique and there are quite a few threads on this site about captive piston technology already ... all the way back to 2005
