You're not bulletproof...

40mm Sub-Caliber insert insanity?

In regards to the “40mm Sub-Caliber Insert” post…

If you read the description completely, it is a cheap alternative. You can’t exactly buy 40mm high explosive shells at the nearest Wal-Mart. If you do locate some, you have to go through extensive NFA paperwork and the $200 tax stamp. This also doesn’t take into account that more than likely you will have to buy bulk surplus. If I remember correctly…if it is a high explosive round, the $200 tax stamp is for each round. So…if you want 6 shells, expect to pay whatever each shell costs + $200 for each of the 6 shells. Tell me how using a cheaper 20 gauge insert isn’t practical?

The purpose of the sub-caliber insert is very much the same reason why some old bolt-action rifles have a .22 LR insert and to some extent, why some handguns and rifles have .22 LR conversions. Cost. Ammo isn’t always cheap, especially if you shoot a lot.

I’m not sure what you’re train of thought is. Obviously if you needed a 40mm shell, then a 20 gauge loaded insert is not the same thing. Are you seriously thinking that someone is going to try and blow up a fortified position or destroy a light vehicle with a 20 gauge shell? 

The rounds below are 40mm High Explosive Practice rounds. These are specific to the MK19 and HK grenade launchers. There is a 40mm High Explosive Practice round for other 40mm launchers at a fairly cheap price of $425 per round. I don’t know about you but I’ll stick to the so-called “impractical” 20 gauge insert.
