Pressure signs question

[Garmil]

I made a new load and tested it in my cz ts and the primers looks a little crated with a small amount of flow. The same load in my glock 24 has a perfect looking strike. Is it safe to assume the round is not over pressure ? The difference in the guns could be making the primers look different?

The primers DON"T lie. What is safe in one gun may be approaching unsafe in another gun. All guns ARE NOT created equal. Pay attention to the overpressure signs!

What's the velocity and bullet weight?

Any sign of bullet setback in your CZ?

[Garmil]

155 gr. Xtreme rn fp

1.135

5.4 gr. commercial #5

1100 fps average

No setback

That's a lot of Commercial #5 for that case size. I've never loaded a bullet that light for 40 cal. I get 1000 fps out of a CZ Tactical Sport using Bayou 175 gn bullets at a 1.15 OAL. I wouldn't be at all surprised if you are pushing the pressure envelop.

With how much powder?

4.75gns With a Bayou 180, I get 175 pf with 4.7.

That sounds about right compared to where my load is. Csb-5 has came close to titegroup data for me. And titegroup data for our 2 bullet weights is right about where we are both at.
