Locktime

[Mike.m]

Hello can someone explain what locktime is

And what a short stroke will do ?
Many thanks Mike

Locktime is mainly used for powder burners- time between trigger being pulled and striking the cartridge, can be applied to a PCP as time between trigger and hammer striking the exhaust valve, don't think you can really apply it to a springer as the firing process starts as soon as you pull the trigger where the piston actually has the effect of moving the pellet is anyones guess.

Locktime is very relevant to spring powered air guns. It is the time from when the trigger sears have parted, the piston has been driven down the compression cylinder, the pellet starts to be driven down the barrel to when the pellet actually leaves the barrel.

Although I have no specific source of info, I had always thought the same a ukniel, however some interweb research turns up several different definitions (many of which would seem to be given with only one type of firearm in mind) and I suspect it is one of those terms that means exactly what you want it to.

FWIW in my opinion, it is only really meaningful if we accept ukniels definition (trigger release to projectile in free flight) since it can then me meaningfully applied to any firearm (even a flintlock or matchlock. crossbow). Can't see why anyone would be interested in how long it takes from trigger release to striking the primer - what use would this info be?

But it doesn't mean you have to relate it to a springer find another term for it. Lock is just that, the firing mechanism, not the time from trigger to projectile leaving the barrel. It's all milliseconds we're talking about but it came about from matchlock to flintlock to cartridge firing times which varied greatly as advances were made

If it's the time from the trigger release to the pellet leaving the muzzle then it might be more appropriate to call it an unlock time.

OK please explain locktime in relation to the function of a matchlock and a flint lock and a percussion lock. The timing starts when and stops when?

Locktime is a function of the firearm itself, what happens after the pin hits the primer is a function of the cartridge.

Very seperate issues

I've always preferred to use the term 'shot generation time' when referring to airguns.

Just saying.

But this relates only to cartridge guns. Do other projectile weapons not have a locktime?

I've always believed it to be the delay between pulling the trigger & the projectile exiting the muzzle.
With a springer it will cover the double recoil so I'd think it extremely important.
