The .410 shotgun is a very versatile gun, with a wide range of cartridges and loads, for pest birds, possums and rabbits. Even solid slugs are able to be used for close range shooting of larger pests. The Rossi .410 .22lr combo with interchangeable barrels is among my most favourite of survival/take-down rifles.
It’s important to understand that the .410 shotgun works best suppressed when using sub-sonic ammunition, and standard/hypers/magnum rounds will be around 35 to 50% louder, even suppressed. This is because the sonic crack occurs when the ‘shot/bb’s” or projectile overtakes its own sound at around 5 mtrs in front of the barrel, and no suppressor can remove this. See other menu listing for how I easily and quickly reduce the load of magnum cartridges to sub-sonic, and you then effectively load each round for the velocity and quietness required.
Below: A few of my .410 projects, this first one I made for Vaughan’s young son, with shortened stock, shortened barrel and compact/lightweight over-barrel suppressor (just over 300 grams).
