You want to have your average...

load be up around 57 ish if you can manage that and assuming that your your variability is kind of small in the 500 to 750 psi range of course we can't measure that you have to be able to measure velocity and hope hopefully they correlate and in most cartridge cases they do correlate pretty well

So different bullet weight and construction, copper jacket, lead cord versus monolithic copper bullets, that affects the peak pressure.

No surprise there.

And the other thing that you need to worry about is you'd really like to have the powder completely burned out while the bullet's in bore to extract maximum velocity out of that powder.

And powder burnout affects muzzle flat.

Burned out's good, not burned out.

Adds to the flash.

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

Okay.

Firearms Radio Network (All Shows)

So are there any questions here?

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

Okay.

We will move on.

What factors increase peak chamber pressure?

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

Okay.

Firearms Radio Network (All Shows)

Increased powder charge.

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

No surprise there.

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

Use of identical charge weight of powder within an increased relative quickness.

Firearms Radio Network (All Shows)
Reloading Podcast 565 โ€“ Jeff from Bulletology

Again, no surprise.

Firearms Radio Network (All Shows)

Increased mass of the projectile.

Again, that bullet...
