BR,
With your info the computer predicted max pressure is 50,232lbs. Max SAAMI pressure for the 6ARC is the same as the Grendel, 52K lbs.

This is Jager's recommended powder tweak for LT32, on the other forum.
[INDENT]LT-32:
1. Heat of Explosion / Potential = 3754
2. Ratio of Specific Heats = 1.2370
3. Burning Rate Factor (Ba) = 0.6545
4. Pro or Degressivity Factor a0 = 3.2400
5. Progressive Burning Limit z1 = 0.387
6. Factor b = 1.9175
7. Propellant Solid Density = 1.560
8. Load Density (calculated factor) @ 100% Fill Ratio = 0.880[/INDENT]
Don't take this as gospel - there are a lot of tweaks here and each can confound the final result like tolerance stacking. I used Grendel as the parent case, A2015 as the parent powder, and your water filled case capacity. If you go even further and match the load density with Jager's then the peak pressure is slightly lower at 49K lbs.
If you trust that the load was OK then the case coming apart was from something else, like insipid case separation - Too much headspace. 25 reloads and that case is doing better than most, but by then even if you sneeze it will come apart.
Do you measure headspace? The difference between headspace before and after firing?
