Can anyone give an estimation of the time it takes from the release of the firing pin until the moment the powder charge is igniting and the bullet starts to move? - for an average .22lr target rifle.

I'm sure you can google that and find an answer. I don't know how long it is but it's millseconds.

Rob.

might be an idea to email Eley with regards to burn times of the propellant

200 milliseconds.

The time is determined on several factors one of them being the temputure of the power itself and this is always true of any inflamable material. The closer to its flame or flash point the faster it will ignite. And, of course the colder the slower it will ignite. Any fire person know this simple fact as it is taught in grammer school to most of us.

Now that's a big help.

Lock time for a target rifle is on the order of 1-4 msec.
Complete combustion of the gunpowder occurs in about 0.5 msec
Assuming a proper lubricant, temperature will have minimal effect on lock time.

I believe the question is the average lock time for a .22 cal target rifle.
Anschutz 1400 series is about 2.3 ms
1800 series about 1.7 ms
2000 series about 1.5 ms

Hope this helps.

Hey Chet, If your powder tempeture idea is so grammar school simple. Please explain why some Master shooters keep their ammo in cooler when the air tempeture is really high.

To the thread, I know I shouldn't post an answer to Chet, but I just couldn't help myself.
