How do snap caps work if the inertia depends on recoil?

Best you do then in case you void any waranty.

The only purpose that a snap caps is needed for is if you are going to dry fire the action. Mechanical parts don't like being released without some sort of control resistance to cushion the stop impact. When the action is fired the primer in the cartridge absorbs the impact as does a Snap cap. It was the practice in the day of the military to practice pulling the trigger and it was referred to as dry Firing practice. Some people do it out of habit. I've seen people in gun shops do it. From a mechanical point of view it is wrong, putting a lot of damaging impact on the small working parts such as springs and firing pins. From a safety point of view it is a potential accident waiting to happen. There is a possibility that at some stage that dry Firing will coincide with a live round up the spout. I have been present on three occasions when Guns have been accidentally discharged. Two into the ground and the other up into the sky. Luckily no one was hurt in any instance. Apart from personal injury If it happens inside it is going to cost a lot to repair replace collateral damage. All three shooters and the people who were present were really shocked by the incidents. There is the old adage about, do not point a gun at something you do not intend to shoot.

Now as this benelli is quite unique and the manufacturer recommends it i do use snap caps on my 828u shot gun.on my other guns I don't bother

Whether or not you choose to use the bloomin things, please, please ENSURE that they remain in your cabinet when you take the gun out.

There handy for checking trigger pulls and suchlike, even dry practice BUT NEVER EVER leave them in the gun either in a slip or in a cabinet. The reason is one day it is possible whilst distracted to accidentally leave a cartridge in and on glancing whilst removing from cabinet assume its a snap cap. Barrels can and indeed must always be checked frequently as in every time you take hold of a gun, pass a gun, slip it or unslip it. This check is for an empty barrell, empty of anything. Hence snap caps for anything other than "testing" something is bad practice

as for snap caps I have never broken a firing pin in my life until I used them and have not used them since the idea of a spring either leaf or coil is to store energy you do not go out every night and jack your car up to take the load off the springs etc as an aid to trigger freeze just needs your mate to shout at you to let go the trigger or to collect £5 every time you do not let go wont take long to sort the problem

my 17 year old browning b425 never saw a snap cap and is always stored

with springs compressed, never had any issues
