So that's the tradeoff.

No, I think the better solution is to limit the number of times you bulge bus.

I suppose you can't really anneal up to the web.

No, don't do it.

Are we ready to move on?

Yep.

Okay, so this is a little graphic I put together that shows the different propellant geometries that are available to us as reloaders.

Going from left to right, we have flake, sphere, cord, single perf, and a type of propellant that still hasn't kind of muscled its way onto the stage yet, but I've had a little bit of experience with, called C4.

Basically, C4 is a cube propellant.

with four perforation.

And the C4 was interesting because we did a big, it's called the design of experiments, trying to figure out what combinations of things work best to get the group small for sniper ammunition.

I was working with Lake City and the C4 did a great job in terms of getting the group small, but it had issues

with the primers that we were using in terms of muzzle velocity variability, the muzzle velocity standard deviation for the C4 was, you know, kind of up in the, um, double digit range and they were looking to get down in the single digits.

And, um, for whatever reason, the C4 didn't like the primers that we were using and we didn't, we didn't have a particularly large, um, um,

selection of primers that we were playing with.

So, um, for, for whatever reason, the primers we were using it, it didn't particularly care for in terms of velocity variability.

Okay.

Um, uh, cord, um, cord powder is used from what I I've got that listed as typical use for rifle as rifle.

Um, I've since learned that that's actually should be pistol.

I know Vita Vori makes a cord propellant for pistol applications.
